A duct joint Is blowing air on the back side of the duct causing the whine. Engineer to review and advise. c) All of the VAV boxes are indexed to the warm-up mode if their respective AHU is in the heating mode. However the BAS point that the VAV control logic references indicating the AHU is in the heat mode was actually the boiler room hot water availability signal and not the AHU heating mode point. This would allow the VAV box to go to max heating airflow when the AHU was not in the heating mode and cause the zone to become cold, Item corrected on site. d) The warm-up mode sequence for all of the VAV boxes is not as indicated in the approved sequence of operation. All VAV boxes are programmed to index the volume damper to provide a warm-up airflow equal to 50%of the cooling airflow for the box. The approved sequence of operation indicated that when the VAV box is in the warm-up mode, the damper shall be positioned to the max airflow position.

However, engineer to verity It compliant with Massachusetts code. j) The DAT reset schedule and operation is as follows: it the space temperature is below 68°F the DAT shall be asset up from 66°F (occupied heating setpoint) to 85'F, i`the space temperatur©is above 74°F (occupied cooling setpoint), the DAT shall be reset from 66°F down to 55°F. All reset DATs are driven by PID logic. A DAT high limit of 85°F is programmed for the control of the hoating valve. Engineer to verity if acceptable. k) Due to seasonal weather conditions, it was not possible to test the control of the chilled water sequence. 1) The defrost sequence is controlled by the unit mounted Honeywell proportional temperature controller and not the BAS.The temperature controller was found set at 25°F. The controller temperature setpoint was changed while on site. The operation of the temperature controller is as foiiows:the controller setpoint is set to 36°F with a 5' proportional range, i.e. controller will modulate open the bypass damper at -33.50 and modulated closed at -38.5 11close. There is no 30 minuto time delay associated with the operation of the temperature controller. Engineer to verify if acceptable. m) The fan failure sequence does not operate per the approved sequence of operation. It is recommended that all fans are shut down and all damper return to their fallsafe positions to prevent possible freeze up of the heat exchanger in the event of an exhaust fan failure. Engineer to review and advise. n) only one dirty filter sensor has been installed at the outside air intake filters on the unit. No sensor has been installed on the return air filter, Engineer to review and advise. o) The OA dirty filter DP setpoint was found at 2" and was adjusted to 1.0" while on situ. Item corrected on site, p) The occupied heating and cooling setpoints are as follows: 68°F heating and 74°F for cooling. q) The condensate drain pan after the heat exchanger and upstream of the dual temperature Coil does not have a trapped drain pipe installed and air is being drawn into the unit.

The status of these items remains open until notified of their corrections. 1. General: a) The zone temperature sensors for the HRUs and constant volume AHUs are flush mounted sensor typically installed on block wall surfaces. The sensors have been installed with a gasket material between the sensor and the wall surface, however, the sensors lag behind the actual space air temperature by a few degrees. In many instances this is causing the space to overheat or overcool while the sensor'catches" up to the actual space temperature. Engineer to review and advise. b) On all of the outdoor HRUs a weather housing is used to cover the externally mounted bypass damper actuator and defrost temperature controller. This housing is open on the bottom and does not totally enclose these devices. The devices appear very weathered. Engineer to verify If devices are rated for outdoor use. 2. HRU-1: a) Supply fan motor efficiency 89.5% vs.the minimum required efficiency of 91%. Supply fan efficiency does not meet the MECo MRD per the energy efficient motor schedule on drawing M4.02. Engineer to review and advise. b) Return fan motor efficiency 87.5% vs.the minimum required officlency of 89.5%. Return fan efficiency does not meet the MECo MRD per the energy efficient motor schedule on drawing M4.02. Engineer to review and advise. c) A face damper has not been supplied with this unit, only a bypass damper is installed. Air is passed through the heat exchanger at all times and temperatures including the defrost mode. Engineer to verify if acceptable. d) The OA cartridge filters are missing from the outside air filter rack. Cartridge filters should be installed. Owner to review.

This scenario is typically found on all other VAV systems. Engineer to review and advise. u) The minimum outside airflow cannot be reliably maintained throughout the full range of the unit with the return air damper locked in the full return position and the return fan off. This is due to the OA damper not being able to reliably control OA airflow at the partially closed damper positions. Engineer to review and advise. v) The duct static pressure setpoint was found at 1.75". This setpoint was reduced to 1.25" and all boxes were able to maintain design max airflow at this static pressure. Item corrected on site. w) The DAT is not being reset based on return air temperature as indicated in the approved sequence of operation, but rather based on the number of zones calling for heating or cooling and for how long they are calling. Engineer to review if acceptable and for compliance with MECo MRD. x) The outside air temperature setpoint at which economization is permitted has been set to 70° F from 65°F this has been changed by the Facilities staff to minimize the operation of the chiller. In the economizer mode,the OA dampers control to a low limit of 55°F DAT setpoint. When the min OA damper reached a 90% open signal, as commanded by the economizer sequence, the two- position max damper is opened. This causes the DAT to rapidly drop below the heating coil low limit of 50°F causing the heating valves to open reheating the air stream. The max OA damper then closes due to temperature overshoot and becomes cyclical. This is wasteful of energy and the sequence and the damper control should be modified to allow for proper modulation of the dampers for better control. Engineer to review and advise. y) Due to seasonal weather conditions it is not possible to test the chilled water control sequence. The control logic has been verified in the BAS. z) Dirty filter DP is piped across both pleated and cartridge filters on the unit. This is not consistent with the other AHU in the facility. Engineer to review and advise. aa) A duct static high limit sensor is not installed in this VAV system. None was called for in the approved ATC submittal. However it is recommended that a safety high duct static sensor is installed to protect the ductwork in the event of a fire damper closure or failure of a the static DP sensor.

This sequence is redundant to the morning warm-up sequence mentioned above. However, because the optimal start sequence is a"smart",this sequence will take precedence over the warm-up sequence above and is the only sequence that will ever operate. It is recommended that the one or the other sequence is left permanently programmed in the BAS and the other removed for simplicity and"house keeping" purposes. Engineer to review and advise. o) Morning warm-up setpoint is set to 69°F. p) The minimum outside airflow setpoint in the BAS was found set at 2700 cfm. That was adjusted to the design value of 2500 cfm while on site. Item corrected on site. q) The return fan was found locked out on the unit, the relief/return dampers have been locked in the full return position, and the min OA damper has been set up to modulate to maintain the min OA airflow. As stated by the ATC contractor,this had been done in conjunction with the balancer due to the negative space pressure and the inability to bring in the proper amount of outside air. The return fan and return/exhaust damper overrides were removed and the unit was tested at 100%speed ion the fans with all VAV boxes to max cfm position. In this mode the OA airflow was measured at 2482 cfm vs. the design OA airflow of 2500 cfm. The modulating minimum OA damper was in the full open position. The return fan airflow was measured at 13,543 cfm vs.the design if 12,500 cfm. Because the return fan and the supply fan are operating on the same speed signal, it is not possible to properly control the return airflow for proper OA and return airflow. Engineer to review and advise. r) Per the ATC contractor the modulating damper actuator that was on the max OA damper has been swapped with the two-position actuator that was on the min OA damper/airflow station (AFS). It appears that this has been done to allow the min OA damper with the AFS to modulate in order to control to the min OA setpoint. However, when the damper begins to modulate closed, the accuracy of the airflow station begins to decrease drastically. In this current operating state is not possible to reliably maintain the proper amount of outside air and return air for efficient energy use and reliable ventilation. Engineer to review and advise. s) When the would enter occupied mode, the PID loop controlling the min OA damper would wind up too quickly causing the min OA to modulate to quickly in order to satisfy the OA requirement. This was causing the unit to hunt excessively to meet the min OA. A time delay was added to the BAS to allow the OA AFS to read airflow prior to commanding an immediate damper position change. Item corrected on site. Upon completing the testing the return fan was placed back into lockout and the return/exhaust damper override back to the full return position. t) The unit was released from operating the supply and return fans at 100% full speed, the VAV boxes were released to normal control, and the minimum OA damper was allowed to modulate to control to the minimum OA setpoint. In this scenario the system airflows were to measured to verify how the system would operate. The following data was recorded: Supply airflow measured 5123 cfm. Return airflow measured 7083 cfm. Outside airflow measured 2554 cfm. Exhaust air measured 4745 cfm.

Item corrected while on site. BAS read an average value of 2550 cfm vs. the measure 2464 cfm. f) The airflow station has some fluctuations in the readings due to the location of the sensor tubing. The return air damper is aimed directly at the min OA damper where the AFS sensor tubing is located. This is causing some turbulence at the tubing and resulting is irregular fluctuations of OA airflow readings. g) The current occupied schedule is 7:13 am to 1:30 pm. Monday through Friday. All other times are unoccupied. h) The exhaust damper is slightly open in the unoccupied mode, however it is not possible to access the exhaust damper linkage to adjust it without removing the RA damper. Damper position should be adjust for full closure of the exhaust damper. Engineer to review and advise. i) Night setback setpoint for all of the zones is set to 55°F. A night setup setpoint of 90°F was found programmed in the system. Night cooling sequence is not an approved sequence per the MECo MRD. As stated by the ATC contractor,the night cooling routine could not be eliminated without cumbersome programming changes. However the setpoint was increased to 100°F to prevent the sequence from ever occurring. Engineer to review. j) Night setback mode is enabled if 3 of the 11 zones are calling for heat and the RAT is less than 66°F. Per the ATC contractor, this was done at the request of the City of Northampton to reduce nighttime operation. The unit will come out of night setback mode and shut down when less than 3 zones are requesting heat or if the return air temperature goes above 66°F. The return air temperature feature will prevent the spaces from reaching the night setback temperature and prematurely shut the unit down. The RAT setpoint feature to control night setback was removed while on site. Item corrected on site. k) It is desirable to have night setback mode enabled when any one zone calls for heat. However, because the same routine is used for heating in all modes, when the unit is in normal occupied mode, and a single zone is calling for heat the unit would be placed into heating mode and would cause the other zones to overheat. This sequence could not be changed without adding additional routines to control separately for night setback. Engineer to review and advise. 1) The DAT was found resetting based on the number of zones calling for heat with a high limit setpoint of 85°F. This was changed to a fixed DAT of 90°F to quickly heat the space up to the setback temperature and reduce the operating time of the AHU during night setback mode. Item corrected on site. m) Morning warm-up is enabled between the hours of 6:00 a.m. and 8:00 a.m. Morning warm-up was found programmed as follows: if more than 3 zones are calling for heat and the RAT is less than 66°F the unit will go to morning warm-up mode. In morning warm-up the heating valves were found to fully open until less than 2 zones are calling for heat and the RAT is greater than 75°F. With the heating valves full open, the space will overheat. The heating valve control was changed to control to a DAT setpoint of 90°F in the warm-up mode. Item corrected on site. Engineer to verify if acceptable. n) An optimal start sequence is also programmed in the BAS. The optimal start sequence resets the zone temperatures up continuously on a range of 10°F/hour until the occupied AN BVH Commissioning Notice Page 15 50 Griff in Road South Bloomfield,CT 06002 mm y_, Tel: (860)286-9171 111te�Tat Fax: (860)242-0236 services www.bvhis.com economizer sequence, the two- position max damper is opened. This causes the DAT to rapidly drop below the low limit of 50°F causing the heating valves to open and reheat the air stream. The max OA damper then closes due to temperature overshoot and becomes cyclical. This is wasteful of energy and the sequence and the damper control should be modified to allow for proper modulation of the dampers for better control. Engineer to review and advise. x) In the present condition with the return/exhaust dampers being lock in the full return position, when the unit enters full economizer mode, no air is being relieved from the space. This will cause the space to be over pressurized. Engineer to review and advise. y) Unable to verify the operation of the chilled water control due to seasonal temperatures. z) Dirty filter DP was found set at 1.5". This was adjusted to 1.0"while on site. There are both pleated and cartridge filters installed in this unit. The DP sensor is installed across the pleated filter only. Engineer to verify if acceptable. aa) Coil water flow was verified. Coil design for cooling is 25 gpm and heating is 10 gpm. Actual measured coil flow rate for heating is 20.4 gpm (1/3 valve) and 23.5 gpm (2/3 valve). Total flow of 43.9 gpm. The final water balancing report indicated the 1/3 valve flow of 13 gpm with at a balancing setting of 1.0, and the 2/3 valve flow of 17 gpm with a balancing setting of 2.7. The actual settings observed were 1.0 on the 1/3 valve and 2.6 on the 2/3 valve. Engineer to review and advise. 10. AHU-8: a) Trane Climate Changer AHUs contain Square D VFDs. Manufacturer's approved submittal data does not indicate VFD efficiency. Documentation is required from manufacture to verify conformance to MECo MRD requirement.

Manufacturer's approved submittal data does not indicate VFD line reactance. Documentation is required from manufacture to verify conformance to MECo MRD requirement. Commissioning agent has contacted the manufacturer requesting the documentation. c) The duct static pressure sensor was found configured to operate in a scale of 0 to 1.25". The sensor scaling configuration was corrected to 0 to 2.5" while on site. The sensor required calibration. Item corrected on site. d) The following performance data was recorded with supply and return fans operating at 100% speed, the minimum OA damper open, and all VAV boxes on this system commanded to the max design cfm: Supply fan: Total airflow measured 16,435 cfm vs. the design of 15000 cfm. TSP measured 2.16" and the duct static pressure measured 0.71". Return fan: Total airflow measured 13534 cfm vs. the design of 12500 cfm. TSP measured 0.8" and the return duct static pressure measured—0.58". e) The outside airflow station installed in the unit is a factory installed Trane static track stations. The BAS and measured outside airflow measurements were not corresponding. It was discovered that the integral outside airf low station controller was providing an airflow velocity value and not an actual airflow value. An area value, and a correction Nth BVH Commissioning Notice _1�w Page 14 50 Griffin Road South Bloomfield,CT 06002 1-, Tel:(860)286-9171 integrated Fax:(860)242-0236 SePY1CeS www.bvhis.com open position. The lack of outside airflow is due to the supply and return fan providing the same airflow. Because the return fan and the supply fan are operating on the same speed signal, it is not possible to properly control the return airflow for proper OA and return airflow. The return fan airflow was measured at 2608 cfm vs.the design if 2500 cfm. The supply fan airflow was measured at 2642 cfm vs.the design if 3000 cfm. The low supply airflow at this operating point is due to the return fan not being properly sheaved. Engineer to review and advise. p) Per the ATC contractor, the modulating damper actuator that was on the max OA damper has been swapped with the two-position actuator that was on the min OA damper/airflow station (AFS). It appears that this has been done to allow the min OA damper with the AFS to modulate in order to control to the min OA setpoint. However, when the damper begins to modulate closed, the accuracy of the airflow station begins to decrease drastically. In this current operating state is not possible to reliably maintain the proper amount of outside air and return air for efficient energy use and reliable ventilation. Engineer to review and advise. q) When the would enter occupied mode,the PID loop controlling the min OA damper would wind up too quickly causing the min OA to modulate to quickly in order to satisfy the OA requirement. This was causing the unit to hunt excessively to meet the min OA. A time delay was added to the BAS to allow the OA AFS to read airflow prior to commanding an immediate damper position change.

The control logic has been verified in the BAS. t) The duct static pressure setpoint was found at 2.0". This setpoint was reduced to 1.5" and all boxes were able to maintain design max airflow at this static pressure. Item corrected on site. u) The duct static pressure was hunting rapidly. The BAS signal to the speed drive is based on a 2 to 10 volt signal corresponding to 12Hz (min)to 60Hz speed on the drive. The BAS was found to have a 10% minimum speed signal in addition to the min voltage signal was not allowing the VFD to ramp down low enough to control to the duct static pressure setpoint of 1.5". The 10% minimum was removed BAS and the PID loop was tuned allowing better control of the VFD. A DP signal "filter' must be added average out the rapid fluctuations in the DP feed back signal to the BAS. ATC contractor to correct. v) The DAT is not being reset based on return air temperature as indicated in the approved sequence of operation, but rather based on the number of zones calling for heating or cooling and for how long they are calling. Engineer to review if acceptable and for compliance with MECo MRD. w) The outside air temperature setpoint at which economization is permitted has been set to 70° F from 65°F this has been changed by the Facilities staff to minimize the operation of the chiller. In the economizer mode, the OA dampers control to a low limit of 55°F DAT setpoint. When the min OA damper reached a 90% open signal, as commanded by the BVH Commissioning Notice Page 13 50 Griffin Road South Bloomfield,CT 06002 EW Tel: (860)286-9171 pa Fax: (860)242-0236 lnte www.bvhis.com services could not be eliminated without cumbersome programming changes. However the setpoint was increased to 100°F to prevent the sequence from ever occurring.

Per the ATC contractor,this was done at the request of the City of Northampton to reduce nighttime operation. The unit will come out of night setback mode and shut down when less than 3 zones are requesting heat or if the return air temperature goes above 66°F.

Engineer to review and advise. k) The DAT was found resetting based on the number of zones calling for heat with a high limit setpoint of 85°F. This was changed to a fixed DAT of 90°F to quickly heat the space up to the setback temperature and reduce the operating time of the AHU during night setback mode. Item corrected on site. 1) Morning warmup is enabled between the hours of 6:00 a.m. and 8:00 a.m. Morning warm-up was found programmed as follows: if more than 3 zones are calling for heat and the RAT is less than 66°F the unit will go to morning warm-up mode. In morning warm-up the heating valves were found to fully open until less than 2 zones are calling for heat and the RAT is greater than 66°F. Commanding the heating valves full open during the morning warm up will cause the space will overheat. The heating valve control was changed to control to a DAT setpoint of 90°F in the warm-up mode. Item corrected on site. Engineer to verify if acceptable. m) An optimal start sequence is also programmed in the BAS. The optimal start sequence resets the zone temperatures up continuously on a range of 10°F/hour until the occupied heating setpoint is reached at the occupied time. This sequence is redundant to the morning warm-up sequence mentioned above. However, because the optimal start sequence is a"smart",this sequence will take precedence over the warm-up sequence above and is the only sequence that will ever operate. It is recommended that the one or the other sequence is left permanently programmed in the BAS and the other removed for simplicity and "house keeping"purposes.

This causes the DAT to rapidly drop below the low limit of 50°F causing the heating valves to open and reheat the air stream. The max OA damper then closes due to temperature overshoot and becomes cyclical. This is wasteful of energy and the sequence and the damper control should be modified to allow for proper modulation of the dampers for better control. Engineer to review and advise. y) In the present condition with the return/exhaust dampers being lock in the full return position, when the unit enters full economizer mode, no air is being relieved from the space. This will cause the space to be over pressurized. Engineer to review and advise.

This sequence could not be changed without adding additional routines to control separately for night setback. Engineer to review and advise. k) The DAT was found resetting based on the number of zones calling for heat with a high limit setpoint of 85°F. This was changed to a fixed DAT of 90°F to quickly heat the space up to the setback temperature and reduce the operating time of the AHU during night setback mode. Item corrected on site. 1) Morning warmup is enabled between the hours of 6:00 a.m. and 8:00 a.m. Morning warm-up was found programmed as follows: if more than 3 zones are calling for heat and the RAT is less than 66°F the unit will go to morning warm-up mode. In morning warm-up the heating valves were found to fully open until less than 2 zones are calling for heat and the RAT is greater than 66°F. Commanding the heating valves full open during the morning warm up will cause the space will overheat. The heating valve control was changed to control to a DAT setpoint of 90°F in the warm-up mode. Item corrected on site. Engineer to verify if acceptable. m) An optimal start sequence is also programmed in the BAS. The optimal start sequence resets the zone temperatures up continuously on a range of 10°F/hour until the occupied heating setpoint is reached at the occupied time. This sequence is redundant to the morning warm-up sequence mentioned above. However, because the optimal start sequence is a"smart", this sequence will take precedence over the warm-up sequence above and is the only sequence that will ever operate. It is recommended that the one or the other sequence is left permanently programmed in the BAS and the other removed for simplicity and "house keeping" purposes. Engineer to review and advise. n) Morning warm-up setpoint is set to 69°F. o) The return fan was found locked out on the unit,the relief/return dampers have been locked in the full return position, and the min OA damper has been set up to modulate to maintain the min OA airflow. As stated by the ATC contractor, this had been done in conjunction with the balancer due to the negative space pressure and the inability to bring in the proper amount of outside air. The return fan and return/exhaust damper overrides were removed and the unit was tested at 100% speed ion the fans with all VAV boxes to max cfm position. In this mode the OA airflow was measured at 566 cfm vs. the design OA airflow of 1500 cfm. The modulating minimum OA damper was in the full open position. Because the return fan and the supply fan are operating on the same speed signal, it is not possible to properly control the return airflow for proper OA and return airflow. The return fan airflow was measured at 4190 cfm vs. the design if 3500 cfm. The low outside airflow at this operating point is due to the return fan not being properly sheaved. Engineer to review and advise. p) Per the ATC contractor, the modulating damper actuator that was on the max OA damper has been swapped with the two-position actuator that was on the min OA damper/airflow station (AFS). It appears that this has been done to allow the min OA damper with the AFS to modulate in order to control to the min OA setpoint. However, when the damper begins to modulate closed, the accuracy of the airflow station begins to decrease drastically. In this current operating state is not possible to reliably maintain the proper amount of outside air and return air for efficient energy use and reliable ventilation. Engineer to review and advise.

The sensor scaling configuration was corrected to 0 to 2.5"while on site. The sensor required calibration. Item corrected on site. e) The following performance data was recorded with supply and return fans operating at 100%speed,the minimum OA damper open, and all VAV boxes on this system commanded to the max design cfm: Supply fan: Total airflow measured 4851 cfm vs.the design of 5000 cfm. TSP measured 3.2"and the duct static pressure measured 2.08". Return fan: Total airflow measured 4190 cfm vs. the design of 3500 cfm. TSP measured 1.1"and the return duct static pressure measured -0.48". The return fan is 120% of the design. Engineer to review and advise. f) The outside airflow station installed in the unit is a factory installed Trane static track stations. The BAS and measured outside airflow measurements were not corresponding. It was discovered that the outside airflow station was providing an airflow velocity value and not an actual airflow value. An area value was included in the BAS programming while on site and the airflow station read properly. Item corrected while on site. At the low end the BAS read 610 cfm vs.the measure 592 cfm. At the high end the BAS read 1525 cfm vs. the measure 1518 cfm. g) This unit is currently scheduled for occupied times of 7:15 am to 2:00 pm Monday through Friday. All other times are unoccupied. h) Night setback setpoint for all of the zones is set to 55°F. A night setup setpoint of 90°F was found programmed in the system. Night cooling sequence is not an approved sequence per the MECo MRD. As stated by the ATC contractor, the night cooling routine could not be eliminated without cumbersome programming changes. However the setpoint was increased to 100°F to prevent the sequence from ever occurring. Engineer to review. i) Night setback mode is enabled if 3 of the 7 zones are calling for heat and the RAT is less than 66°F. Per the ATC contractor, this was done at the request of the City of Northampton to reduce nighttime operation. The unit will come out of night setback mode and shut down when less than 3 zones are requesting heat or if the return air temperature goes above 66°F. The return air temperature feature will prevent the spaces from reaching the night setback temperature and prematurely shut the unit down. The RAT setpoint feature to control night setback was removed while on site. Item corrected on site. j) It is desirable to have night setback mode enabled when any one zone calls for heat. However, because the same routine is used for heating in all modes, when the unit is in normal occupied mode, and a single zone is calling for heat the unit would be placed into BVH Commissioning Notice Page 8 50 Griffin Road South Bloomfield,CT 06002 Tel:(860)286-9171 integrated Fax: (860)242-0236 services www.bvhis.com a) Outside air ductwork has not been insulated as per the specification section 15250, page 8.

Engineer to review and advise. v) Humidifiers were found shut off. As informed by the facility staff, the units were shut down due to a faulty airflow switch that enables the humidifiers to operate with proof of airflow. The staff stated that the switch has failed in the open position and would allow the humidifier to run with the AHU off. Unable to get the humidifier to operate after energizing the units.

The night setback operation was programmed such that if any 2 zone's temperatures fell below the setback setpoint the unit would call for heat and start the AHU. In the night setback mode the supply fan VFD controls to the duct static pressure setpoint and the heating discharge temperature was found to reset from 60°F linearly up to 85°F base on the space temperature. The discharge air temperature setpoint was changed to 90°F while on site. This will allow the space to heat up to the night setback temperature quickly and minimize run time of the unit. Engineer to verify if acceptable. j) Morning warm-up is based a request for heat from the 3 zones served by the unit. The zone warm-up setpoint is 69°F. The unit will enter morning warm-up mode if 2 zones are calling for heat. If only one zone is calling for heat the unit will enter occupied mode and the OA damper will open and the unit will go directly to the occupied mode. Engineer to review. k) The return and relief damper actuators were found spinning on the shafts and not driving the dampers. Item corrected while on site. 1) The relief damper was found wired backwards and not driving the damper. Item corrected while on site. m) Minimum OA airflow per the schedule is 13,200 cfm. However the unit has not been set up to properly track for minimum outside air flowrate. The return and mixing dampers have not been properly setup to allow the correct amount of return air to the unit and were found over pressurizing the mixing plenum preventing the unit from receiving the correct amount of outside air. This in turn causes OA dampers to open fully which are controlled by the OA airflow station trying to meet the min OA setpoint. Additionally, the poor location of the OA airflow station is making accurate airflow measurements difficult. Engineer to review. n) In order to achieve the min OA airflow of 13,200 cfm, the return and relief dampers were modulated in unison to achieve a calculated mixed air temperature of 58°F based on an OAT of 41.7°F and RAT of 69°F. This corresponds to a return airflow of approximately 11,800 cfm and 8200 cfm of exhaust, with a 25000 cfm supply airflow. The corresponding damper voltage of 5.0 volts for the return and relief dampers was used to set the damper position to assure the minimum outside airflow is maintained.

Additional Items Requiring Attention: a) The Viesmann hot water boilers presently use outdoor air sensors that have been mounted in the courtyard area on an Easterly exterior wall. The Viesmann boilers use this sensor to reset the boiler water temperature. The outdoor air temperature was measured at 28 degrees and the Viesmann boiler controls showed an Outdoor air temperature of 34 degrees. The sensors are recommended to be either relocated to an appropriate wall or have a sun shield installed to avoid incorrect temperature measurements. Engineer to review and advise. b) The Viesmann Representative was contacted and asked to meet with us during our site visit last week. The boiler water temperature was adjusted so that 180 degree water would be discharged from the boilers. As the discharge water temperature approached 170 degrees, the relief valves at the boiler began to lift open. Pressure in the boiler was approximately 26 psi. Relief valve settings were 30 psi. The following should be checked: i) Fill pressure and cold water make-up valve should be checked for proper settings. ii) Check expansion tank. Has expansion tank been properly charged? iii) We understand that the relief valves were discharging regularly during construction. (four total)The springs within the relief valves maybe"tired" and may have to be looked at for replacement. c) The Viesmann representative (Paul Ross) reset the slope adjustment from 2.0 to 1.8. This affects the hot water reset schedule. The slope adjustment to 1.8 would run the boiler water temperature lower than the 2.0 slope. The 2.0 slope would run the boiler water temperature well over 200 degrees at an outdoor air temperature of 5 degrees. Item corrected on site. d) Found the secondary dual water temperature pumps set to maintain a differential pressure setting of 32 psi. Original water balancing report indicated that the DP sensors were set to maintain a 6 psi differential. This needs to be clarified by the Water Balancing Contractor and the ATC Contractor for proper setpoint. e) Found all the variable frequency drives for the dual water temperature pumps set in the "Hand" mode of operation. Pump P-4 was set at 50%, pump P-5 was set to 30% and pump P-6 was set to 30%. Pumps were set back to the "Auto" mode of operation while on site. f) Pump P-6, when operating above 30% speed, is abnormally very loud. We strongly recommend that the pump be checked by either the mechanical contractor and/or the manufacturer representative for proper operation.

Therefore no heat is provided to the band room in the night setback mode. Engineer to review and advise. f) The morning warm-up setpoint was found programmed at 55°F. This setpoint allowed the outside air dampers to open when the space was at 55°F preventing an optimally efficient warm-up strategy. This setpoint was changed to 68°F while on site. Item corrected on site. Optimal start routine has also been programmed for this unit for morning warm-up sequence. g) The discharge air temperature low limit setpoint for economization was found set at 60°F and not 55°F as indicated in the sequence of operation. Additionally, due to EF-5 being disabled, and the OA damper being positioned fully open in order to achieve the minimum outside air, modulating the dampers for full economization has been locked out. Engineer to review. h) The relief air damper has been locked closed due to EF-5 being disabled. Engineer to review. i) Operation of the change over to chilled water could not be verified due to the seasonal weather conditions. j) Operation of the dual temperature control valves in chilled water mode could not be verified due to the seasonal weather conditions. k) Prefilter DP setpoint was found at 1.0". Changed setpoint to .5"while on site. There is no final filter DP sensor. None was called for in the sequence of operations. Item corrected while on site. 1) Coil water flow was verified. The automatic control for these valves is as follows: the 1/3 valve shall modulated to maintain the discharge air temperature setpoint. If the 1/3 is fully open and unable to maintain the setpoint the 2/3 valve shall modulate open. Coil design flow rate for cooling is 39 gpm and heating is 37 gpm. Actual measured coil flow rate is 21 gpm (1/3 valve) and 39.5 gpm (2/3 valve). Total flow of 60.5 gpm. This unit is receiving greater than design water. It should be noted that the balancing valve setting for the 1/3 valve as observed during the commissioning did not match the setting as reported in the water balancing report. The balancing report indicated a setting of 1.5 for the 1/3 valve vs. the observed setting of 3.0. Engineer to review and advise. m) Coil freezestats have not been specified. The dual temperature system has a 40% glycol mixture specified. n) The outside air ductwork from the louver to the unit is not insulated. Per the specifications section 15250, page 8, all plenums and main ducts from the outside air louver to the AHU shall be externally insulated. Engineer to review and advise. o) The exhaust air ductwork from the exhaust/return fan to the louver is not insulated. Per the specifications section 15250, page 8, exhaust ductwork from the return/exhaust fan to the exhaust louver shall be externally insulated. Engineer to review and advise. p) Duct access doors have not been installed at the relief damper from EF-5. Per the specifications section 15880, page 18, duct access doors shall be installed at each control device location and at each location where equipment is installed in the duct.

The status of these items remains open until notified of their corrections. 1. AHU-2 & EF-5 a) The return fan EF-5 was found shut down upon arrival. Based on the information from the operating staff, EF-5 was shut down due to a negative space pressure issue. With the return fan off, the supply fan airflow was measured at 5220 cfm vs. the design value of 5000 cfm. The balancing report indicated a supply airflow of 5195 cfm. In this state the unit was achieving the minimum outside airflow and return airflow without the return fan operating. EF-5 was energized and the return airflow was measured at 5462 cfm vs. the design value of 4000 cfm. The air balancing report indicated a balanced return airflow of 3910 cfm. Based on this information it is obvious that the space was negatively pressurized. Additionally, the return fan was found pressurizing the mixing plenum preventing the proper amount of outside from being brought into the unit. Engineer to review. b) Return dampers were found unable to close 100% leaving approximately V gap in the damper blades. Damper linkage was corrected while on site. Item corrected on site. c) With unit at 100% outside air, airflow measurement was 5220 cfm vs. the BAS reading of 3577 cfm. This OA airflow station is a Trane static track station with its own controller which is calculating the airflow and providing a signal to the BAS. This unit requires calibration by Trane. The location of the outdoor airflow station is in a location that is prone to turbulence. It is recommended that the OA intake is located higher on the OA plenum, permitting a longer duct drop to the unit. Recommend locating the flow station in the longer drop or set the damper to a min position. Engineer to review and advise. d) The occupancy schedule for this unit was found as follows: Occupied time 7:12 am to 12:30 pm Monday-Friday. All other times are unoccupied. e) The night setback mode for this unit consists of providing heat from fin tube radiation only in the space and not running the AHU.

REAR CYCLORAMA- We suggest installing a full-length white cyclorama curtain on the two scenery battens preceding the last batten (holding the back masking curtain.) This curtain should be made of white muslin sewn flat with tie lines on both the top and bottom. By utilizing two adjacent scenic battens, this curtain can be flown out of the stage space entirely. This curtain will provide a plane to project images during stage and concert production. It is a standard addition to any stage softgood set. 636 DANIEL SHAYS HWY. • BELCHERTOWN, MA. 01007 VOX(413) 323-7803 www.theatflx.net FAX(413)323-7805 have to be achieved using a balcony rail or tormentor position. These are generally very inadequate lighting positions due to their low angle of incidence. Maintaining the architectural integrity of the space should be balanced with ensuring the ability to effectively utilize the auditorium for its intended purpose. Today's modern lighting technology and requirements necessitate the addition of this lighting position. 6. Softgoods 6.1. It should be noted that either through intentional or accidental omission, the renovation specifications do not mention curtains of any type for the stage. Because of this, we have prepared the following list of our suggestions for softgoods on the stage. All curtains would be attached to moving battens making their removal and attachment easy for cleaning, maintenance or staging requirements. 6.1.a. FRONT TRAVELER &VALENCE - We suggest a front traveler attached to the existing track. The existing track having been maintained and moved to the old fire curtain line set. The main traveler can be made in your choice of color. We would suggest using polyester velour for strength and stain resistance with a permanently flameproofed treatment. The curtain should be made with 50% fullness and a matching valence installed in front of it. 6.1.b. MID STAGE TRAVELER - We suggest a mid stage traveler attached to a new track flown from one of the available scenic battens. The curtain should be made of 16oz black commando cloth with 50% fullness. 6.1.c. REAR MASKING CURTAIN - We suggest a rear masking curtain attached directly to the last scenic batten. The curtain should be made of 16oz black commando cloth with no fullness (sewn flat). Due to the proximity of this curtain to the rear wall and the lack of any doors on the rear wall, it is unnecessary for this curtain to travel. 6.1.d. BORDER MASKING AND LEGS - We suggest three sets of border masking and leg "portals". This arrangement is made up of a border (or teaser) running horizontally along the stage ceiling with a set of vertical legs hanging down on either side. This provides masking for the light battens and stage wings while creating masked entrances to the stage on either side. Two of the portals should be hung from the scenery battens that precede the lighting battens with the third set being able to be moved around to provide the most effective masking from production to production. - 636 DANIEL SHAYS HWY. • BELCHERTOWN, MA. 01007 VOX(413) 323-7803 www.theatrix.net FAX(413)323-7805 be maintained and reused in position 2 as outlined in the above paragraph. 5.1.c. Position 5 - Electric#1. The current fly system in place for electric #1 is a worm screw, wall-mounted winch and is inadequate for electric batten use. It is flown from 4 points with the points being chain pulley blocks mounted to the overhead concrete ceiling, not from the main I beams. There is no counterweight. Due to the anticipated load of today's modern electric battens it is recommended that a chain motor hung, engineered lighting truss system be installed. This system would provide a box type, aluminum truss, flown from a chain motor on each end controlled by a key lock switch panel. This system provides for larger weight loads, an integral place to mount the electric connector strip and a very high degree of safety. This type of flying system would be used for all of the three electrics to be mounted on stage. 5.1.d. Position 6 through 10 - Scenic battens. These positions should be maintained and refurbished in the manner outlined under section 3, General Renovation Suggestions. 5.1.e. Position 11 - Electric#2. This position should be renovated in the manner outlined under paragraph 5.1.c. 5.1.f. Position 12 and13 - Scenic battens. These positions should be maintained and refurbished in the manner outlined under section 3, General Renovation Suggestions. 5.1.g. Position 14 - Electric#3. This position should be installed new with the same inclusions as outlined above in paragraph 5.1.c but noting that there is currently no flying position in place here. This will permit the proper placement of the upstage electric in relation to the last three, upstage fly's without encumbering the rear, stage left exit door. 5.1.h. Position 15 through 17 - Scenic battens. These positions should be maintained and refurbished in the manner outlined under section 3, General Renovation Suggestions. 5.2. Front of House Electric (Electric #4) 5.2.a. It is recommended that the fourth electric position scheduled for installation in the auditorium be installed as a dead-hung, ceiling mounted lighting batten located over the extreme edge of the orchestra pit where it meets the audience floor seating and placed such that it permits the easy and occasional use of a man lift to maintain and focus the lighting instruments it holds. This lighting position is necessary to permit the proper lighting of the stage with the correct beam angle. Without this position, all front lighting will 636 DANIEL SHAYS HWY. • BELCHERTOWN, MA. 01007 VOX(413) 323-7803 www.theatrix.net FAX(413)323-7805 loads, integral electric wiring points, highly flexible lighting instrument mounting positions, scalable point spreads, easy service and maintenance and keyed switch use. Due to the lack of a loading gallery, the use of chain motors to raise and lower the electric battens is virtually a necessity. Using a counterweight system, the electric battens would need to be raised and lowered each time a single lighting instrument is added or removed to add or remove a counterweight on the arbor to ensure even the smallest amount of safety. It is our experience that this technique is rarely, if ever practiced. It is far too easy to forget about the weight changes when the batten is in its lowered position to remove multiple lights. After removing the lights, the operator will invariably proceed to pull the rope lock handle, forgetting that he or she is now hundreds of pounds out of balance therefore sending the light batten rocketing to the ceiling while the now-overloaded counterweight arbor comes plunging downward, directly over their head. This is a dangerous situation, which must be avoided. Lighting battens with their associated cabling, connector strips and accessories are far too heavy to be moved without motorized assistance, especially in the absence of a loading gallery. Hand crank winches are slow and are only as structurally safe as their points of attachment. They are rarely specified and when used, are utilized in very small load applications. 5. Itemized Renovation 5.1. Following is a list of each position with a recommendation for its continued use and refurbishment. The listing starts at the extreme downstage position and moves upstage. 5.1.a. Position 1 & 2 - Fire Curtain. Two arbor flying system designed for a Braille curtain. The redesigned auditorium is being furnished with a sprinkler system therefore eliminating the need for a fire curtain. We recommend the maintenance and refurbishment of the fire curtain line set and counterweight for use with the main valence and traveler. This line set is designed standard as a fire curtain system, separate from the all other line sets, with a lattice track arbor guide. Utilizing this set for the main valence and traveler would provide the lowering of these softgoods to stage floor level providing easy removal and re- hanging for maintenance and cleaning. 5.1.b. Position 3 & 4 - Main Valence & Traveler. Each position is a single, dead-hung, 1%" black iron pipe. These positions should be removed to increase available space for Electric#1. To avoid fly position number shifts, these position numbers should be deleted (skipped). The main traveler track appears to be in adequate repair and should • •' ., 636 DANIEL SHAYS HWY. • BELCHERTOWN, MA. 01007 VOX(413)323-7803 www.theatrix.net FAX(413)323-7805 4.4. The project architect should review the weight loads being applied to the roof I beams (see table E in specification) and have a qualified structural engineers approval before proceeding. We don't anticipate any problem with the load presented as we have actually de-rated the normal loading by 50% but structural evaluation is beyond the scope of this report. 4.5. All scenery battens are currently 11/4" black iron pipes flown off 4 points with a distance of 15 feet between points. The current USITT standard for point spread on 11/4" black iron pipes is 10 feet. All scenery battens should be replaced with iron truss battens. These truss battens resemble a horizontal ladder with one side attached to the points and the other hanging directly below it. The batten's construction makes it extremely rigid for its size. This would permit greater distances between points because of the inherent rigidity of trussing, thereby permitting the use of the current point spread and preventing the need for the use of bridal attachment points. Bridals are upside down "Y" shaped cable arrangements, which provide two attachment points from a single fly rope. Bridal attachment points would reduce the overall flying height by 5 to 6 feet; an undesirable effect. 4.6. All scenery batten positions are currently rigged with a wire guided, counterweight arbor with an individual, adjustable combination floor block. The entire system should be replaced with a wire guide rail with locking rope locks. The rail system would help to enclose exposed moving parts, increase stability to the wire guide system and provide integral key locks that prevent the unauthorized use of any fly position that is locked. 4.7. All wire rope should be replaced. All hemp pull ropes should be replaced with multi-line 2 or stage set X rope. 4.8. All positions should be adjusted to reflect a final stage trim height of 20 feet, stage to batten. 4.9. As stated, the current renovation specifications call for the continued use of the two existing hand winches for the electric batten positions. The specifications also call for two additional electric positions on stage. In our opinion, three electric battens on stage are sufficient, (and standard for the stage size) and the fourth electric should be moved to a front of house position. (See section$2 below) The current hand winch positions should be removed in their entirety and replaced with a box truss, chain motor system. This system removes any and all danger of counterweighing systems from the light batten positions.

The winch system requires the operator to crank an open worm gear, which can easily trap hair and clothing. One of the winch positions is mounted 6' from the stage floor, over a door opening, thereby requiring the operator to stand on a ladder. Current specifications for the auditorium and stage renovation call for the reuse of these winches. This is not advisable and would not meet USITT acceptable standards. Beyond the mention of the two existing winches, there is no other reference to stage rigging systems within any of the renovation specifications. 4.2. The original fly system construction did not include a counterweight loading gallery. A loading gallery is a railed walkway, or perch, located high along the stage wall running parallel to, and directly over the fly rope pin rail. The gallery provides a place to store, load and unload the counterweights which are placed into the arbors that balance off the changing loads of lights and scenery suspended from the battens. With the use of a gallery, weights may be added or removed as required while the scenery or lights are being added or removed from the batten without having to run the arbor up and down. Thus, the entire fly position is kept in constant, relative balance. Without a gallery, the batten (and therefore the arbor) must be run up and down repeatedly during the change. In the case of large scenery changes where the entire piece must be removed or attached at once, the result is having to apply enough human resistance to the arbor rope to balance the weight of the loaded or unloaded scenery. This is an inherently dangerous situation and should be avoided. However, small pieces of scenery may be safely handled. The current system, after renovation, should be derated to only permit smaller loads. This can be accomplished by: • preloading the arbor with enough weight to balance the empty batten itself • attaching wire locks that prevent the removal of the basic counterbalance weights, and • reducing the arbor's overall weight stack area to restrict the amount of weight allowed 4.3. Deration of the permissible load would also address a second issue. The existing head blocks contain 8" pulleys, however, the existing under hung loft blocks are 6" in diameter. Lowering the permissible weight will allow the use of smaller wire rope through the loft blocks and bring the 6" radius of the pulleys closer to the acceptable USITT standards. \/ _7 •/ Li\.lLiiLl\ulil\Y ii�VYVViiVl\ VV1\Li�LLViil\\.. 636 DANIEL SHAYS HWY. • BELCHERTOWN, MA. 01007 VOX(413) 323-7803 www.theatrix.net FAX(413)323-7805 1 . Rigging Report 1.1. The scope of this report is to outline our findings after inspection of the Northampton High School stage rigging system and review of the current renovation specifications and to offer suggestions for the effective refurbishment and upgrade of the system during the auditorium's current renovation. 2. Current System 2.1. The current rigging system is comprised of 16 batten positions of varying use. All positions are flown on four points with an average distance of 15 feet between points. All positions except for positions 3 & 4 (dead-hung) and 5 & 8 (winch driven electrics) are comprised of a wire guided, counterweight arbor with an individual, adjustable combination floor block. All arbor sets are located on the stage left wing wall, except for positions 14 through 16, which are located mid-floor near the rear, stage right wall. In this report, these positions will be renumbered 15 through 17 to accommodate the addition of a new position 14 which will be the new Electric #3. 3. Opinion 3.1. In our opinion, the rigging system, in its current condition, is in moderate disrepair and potentially hazardous. It is however, restorable and through proper renovation, maintenance and deration, can be brought in line with most USITT standards and provide many years of useful and flexible operation for the school district. It should be noted that there currently exists, no state or federal set of stage rigging requirements or guidelines. The USITT (United States Institute of Theater Technology) has however, assembled a set of stage rigging standards, which is generally considered to be the practical requirements in this field. We have used these standards for comparison in evaluating your rigging system. 4. General Renovation Suggestions 4.1. Currently, electric battens are flown without counterweight utilizing hand cranked, wall mounted winches. These winches collect a single wire rope attached to a four-line clew plate with smaller wire ropes running through a head block to chain mounted pulley blocks. This system is completely inadequate and dangerous. All of the weight of the electric batten must be held by four%" bolts installed during the original construction of the building Mr. Joseph Misterka -3- April 7,2000 cleaning by the use of a lift. We believe that the cost estimate provided by Theatrix is low. One factor is the lack of prevailing wage rates for labor. The cost of a lift to access the high roof is also considerably higher for the amount of time it would be required. The General Contractor could provide the lift at time and material cost. The cost of replacement of the existing rigging system as we proposed above is most likely comparable to the total shown, but a new estimate would be required based on the approved replacement scheme. With your approval, I will address this issue with the Building Committee on April 10, 2000. I understand that this information is probably overwhelming and confusing, and will make an attempt to simplify the language in my discussion. If you have any questions,please call me.

However, we recommend the provision of four wall/floor mounted manual hand winches, not the box truss, chain motor system. Although the use of electric battens facilitates the raising and lowering of lighting, it is not necessary for the scale of productions and the frequency of their use in a school. With careful and knowledgeable handling of the system, the use of the manually operated hand winches is an acceptable practice. In addition, we do not recommend the fourth lighting position be moved to the front of house position. It would have to be dead-hung, therefore making it difficult to access. Also, the new lighting provided at the back of the house is sufficient for lighting the stage. • Paragraphs 5.1a and b: Contrary to the report, the fire curtain is a requirement of the Massachusetts State Building Code 780 CMR regardless of the provision of a sprinkler system. As you are aware, we have received a variance from the State Building Code Appeals Board for its deletion. However, we do not recommend the reuse of the existing line set and counterweight for use with the main traveler and valence. These were damaged during the abatement and removal of the existing fire curtain. The main traveler and valence should be dead-hung on new pipe, closer to the proscenium wall, to allow space for the first electric position. (The remaining paragraphs have been addressed in preceding commentary.) • Paragraph 6.1a: The replacement of stage curtains was not included in the scope of work of this project. The main traveler and valence are currently in storage, are fairly new and in good condition. These do not need to be replaced. I am not aware if there are additional curtains in storage, but the following is our recommendation if they do in fact need to be replaced. • Paragraph 6.1b: The 16-ounce black commando fabric for the mid-stage traveler curtain is not durable. We recommend a cotton fabric such as Atlas Oxford or a synthetic fabric such as Reno Vegas. • Paragraph 6.1c: We recommend that the rear-masking curtain does travel and CONNECTICUT that it be mounted to a dead-hung track. This will allow it to be moved out 416 slater Road of the way, preventing damage to the curtain, in order to access sets or P.O. Box 2590 equipment stored on the back wall of the stage. The fabric for this curtain should also be as noted above. New Britain,CT 06229-0591 Phone:(860)229-0361 • Paragraph 6.1d: Three sets of border masking and legs are acceptable. These can be dead-hung. Fax:(860)229-5303 • Paragraph 6.1e: The rear cyclorama curtain is an optional accessory,_ y p usually used in dance performances. We recommend natural in lieu of white. In MASSACHUSETTS addition, a rear projection screen is included in this project and has been 124 Grove Street approved in shop drawings. Suite 215 Franklin,MA 02038 In summation, we recommend the complete replacement of the existing rigging Phone:(508)520-9928 system as described above. The use of electric winches is not required and not Fax:(508)520-0856 recommended for this installation. Floor and wall mounted, manually operated hand winches are acceptable. A cost savings could be realized by installing only the lighting battens on winches, installing the scenery battens on sliding tracks, and Web:www.kba-architects.co E-Mail:kba m providing dead-hung curtain battens.

Upon review with my consultants, Mr. Erwin Steward (theatre lighting consultant) and Mr. Joseph Drobka (stage and Jamie L.DiPinto rigging), we concur that the existing rigging system is potentially hazardous, and Vincent R.Amrhein based on the information included in this report, will most likely not support the Traci H.Milikowski weight of the new lighting. However, we are not in agreement with the proposed Scott J.Mangiagh changes and offer the following commentary. Terry A.McDonald 0 paragraph 4.3: Derationing, or more simply stated, reducing or restricting the John W.)urns permissible load of the existing arbor's weight stack area is not a realistic Lawrence P.Trim solution to the inadequacy of the head blocks. If more weight is required for Scott D.Pellman varying configurations of the lighting, restricting the weight stack area does not necessarily eliminate the possibility of using additional counterweights in an unsafe manner, i.e., by overstacking or overhanging counterweights. We CONNECTICUT recommend the replacement of the existing head blocks. 416 Slater Road • Paragraph 4.5: The provision of truss battens is not required. The scope of this P.O.Box 2590 project includes four new sets of triangular shaped lighting battens utilizing the New Britain,CT 06050-2590 existing 1 1/4"black iron pipe. Based on this analysis, we recommend replacing Phone:(860)229-0361 the existing pipe with 1 t/2" diameter schedule 80 pipe, and reusing the existing Fax:(860)229-5303 15'-0"spacing between points. • Paragraph 4.6: Wire guided systems should not be used for stages with a height MASSACHUSETTS greater than 30'. The stage height is approximately 40'-0". We recommend replacing the existing system with rigid channel guides and rope locks for this 124 Grove Street installation. In addition, it is possible that the counterweight arbor contains cast Site 215 components, which do not meet today's safety requirements. Franklin,MA 02038 . Paragraph 4.7: We concur. Phone:(508)520-9928 . Paragraph 4.8: We are not clear on this statement. We interpret this to mean that Fax:(508)520-0856 all battens will be held at 20'-0" above the stage floor. This is the approximate height of the proscenium opening.

Due to constraints of existing construction it is not feasible to install a ramp to the Upper Auditorium Lobby area. The required width of the passage is 6'-0' and is considered a corridor, not a stair. Installation of an inclined wheelchair lift would impede on the required width of the corridor for egress purposes. Furthermore, two means of egress are required from this area and a wheelchair lift is not considered an accessible means of egress by 780 CMR. Section 1007.1. A variance is requested to allow a change in level that includes an existing stair to remain, therefore allowing the existing Lobb; and Balcony areas to remain non-accessible.

This egress configuration is it result of existing construction constraints and the lack of any possibility for providing an accessible egress route at the front of each theater. Modification to the existing concrete slab on grade will be made in the ;auditorium to provide level wheelchair spaces. A variance is requested to allow wheelchair spaces to be clustered at the rear of the theater and not dispersed throughout as required by Section 14.4. 'I'he existing slope of the floor is less than 1:12, allowing handicapped access to the front of the theater. However, for life safety considerations, the wheelchair spaces are located at the rear of the theater adjacent to the accessible entrances in order to eliminate the crossing of occupants in an emergency egress Situation.

Commonwealth Opera, a Regional Opera Company with its home base in Northampton Massachusetts has been providing the area with productions of Grand Opera and Broadway Musicals for 23 years About 3 years ago, we used the Northampton High School as a venue for our production for the first time and found it economical as well as an ideal place to perform for a variety of reasons The lobby at that time was in very sad shape, so the company took upon itself to clean repair and refurbish and paint it in the original Art Deco style of the original. After much historical investigation, we proceeded to paint the area in multi earth tones with the finished product garnering much praise from everyone. The entry was easily accessible to patrons and the existing ramp, adjacent to the auditorium, made it very easy for wheel chair patrons to be a pan of our audience for our first production in Congdon Auditorium at the Northampton High School. That production was"Brigadoon We have since performed there numerous times including a collaboration with the Northampton Lions Club on their project to renovate the entire inside of the auditorium. The entryway from outside is very visible and separate from the entry to the school itself, making it an ideal entrance for the auditorium and any productions that may take place there. This entrance, along with the adjacent wheel chair ramp creates a separate and, when lit at night, a very visible and accessible entrance to the auditorium. We would very much not like to sec this entryway changed in any way if at all possible. Thank you for allowing us to share our comments on the Northampton high School renovations.

The Northampton Lions Club is much concerned over the proposed changes to the cntryway to Condon Auditorium at the Northampton High School. The local Lions Club has put two years of effort and raised over S50,000 00, all of which was put into the restoration of the auditorium. This was made possible with the generous help of local businesses, educational institutions,companies and individuals. As it stands now, the entrance is a wonderfully separate and stylized area. Keeping it distinct from the school entrance itself and as unchanged as possible, we feel will add to the historical and architectural integrity ofthe building. We are also concerned for the Large Engraved Plaque that we have mounted in the outer entrance area that holds all the names of donors to this tremendous Northampton Lions Club project. Working with various organizations and producing ourselves a gigantic kick off concert for this project,we can attest that the wheel chair ramp currently located immediately adjacent to the auditorium works fine. We had neither problems nor complaints from those who required this facility It therefore seems to us unnecessary to destroy the current entrance for this purpose. We understand that in the proposed renovations, a ramp adjacent to the auditorium will be available. This sounds most reasonable to us, and we would ask that you consider not changing the main,auditorium entrance.

The intent of the DDC system with respect to the boiler plant is to provide monitoring, enable operation, lead boiler selection, automatic switchover if lead boiler fails, combustion air operation, pump operation, hot water reset and boiler room ventilation. We do not recommend removing this level of control from the DDC system. Item #12: (15950) In an earlier memo, the Energy Commission requested a "Native BACNet " DDC control system for this project. This is currently specified and is non-proprietary since there are several manufacturers today that are complying to the BACNet Standard, however, several other manufacturers still do not comply and require "gateways" to be able to communicate with other manufacturers. Gateways cannot be allowed in a "Native BACNet" specification and therefore this may appear to be proprietary. Item #13: (15950) All setpoints are adjustable. Item #14: (15950-17) We will upgrade the global controller back-up memory by addendum. Item #15: (16500) We are in the process of verifying compliance with Mass Electric Design 2000 program literature with a Mass Electric representative. .. t Item #16: (16500) Typical classroom lighting consists of two rows of direct/indirect pendant mounted fixtures each with (3) 32watt lamps per 4'-0" section. The row closest to the building exterior window wall will have the two outboard lamps on dimmers, controlled by a light sensor in the room. The fixture type for the dimmable type fixtures is "C5". Item #17: (E1.08) Light fixture type "G11" is specified on the Light Fixture Schedule on final contract drawing E4.01. Item #18: (E 1.11) Light fixture type "GG" has been changed to type "H" and "H 1". Fixtures "H" and "H1" are HID Hi-bay Industrial type lights. Item #19: (E1.14) We do not recommend the use of occupancy sensors in rooms where the occupants may be at risk if the light fixtures were to go off, even momentarily. Item #20: (E1.14) Desired lighting levels in Science classrooms require a greater number of fixtures than could be practically arranged in rows parallel to exterior walls. The layout shown on the plans should provide the best lighting performance. Item #21: (E1.15) See item #19. These-types of spaces may have tripping hazards and/or ongoing processes that could prove hazardous in the event that lights are shut off. Item #22: (15550-3) This is actually the combustion efficiency at the specified design temperature. As hot water supply temperature is reset, the efficiency increases.

Item #2: (15850-10) We do not recommend using a hot water coil to heat 100% outside air. Item #3: (15880-7) Yes. Item #4: (M4.02) We do not recommend installing a variable frequency drive for a 3/4 horsepower motor. Item #5: (P2.01) Consult with the Kitchen Consultant. We have it as electric. Item #6: (P1.04) This item was previously discussed with the y Commis*on and it was determined that electric is best, avoiding flue and combustion air requirements. Item #7: (15400) This item was deleted by the Energy Commission per our phone conversation of January 27, 1999. Item #8: (15410-6) This item was previously discussed with the Energy Commission and it was determined that a separate gas fired domestic hot water boiler is best since the heating system fluid contains 40% propylene glycol and expensive double wall heat exchangers would be required. Item #9: (15950-15) We will upgrade the computer specifications by addendum. Item #10: (15 950) We will add a gas usage meter with DDC points for trend logging gas usage by addendum. 16500 It is unclear from the specs whether all of the lighting fixtures (and motors) comply with the maximum Massachusetts Electric Co. Design2000 rebate (for fluorescents this means Code 30 and Code 32 fixtures) . This is an important requirement of the Northampton Energy Policy that we had previously discussed. We request that the specs reference the Mass Electric rebates . Also, it is important that the Design2000 application forms be completed and submitted to Mass Electric as soon as possible, to take advantage of current rebate levels before they change this Spring. 16500 A typical outside row of ballasts in classrooms be should be dimming, "C5" not "C" . E1 . 08 There doesn' t appear to be a light "G11" on the schedule. E1 . 11 Unclear what a GG fixture is? E1 . 14 Science-type classrooms should have occupancy sensors . We know there is a safety issue here, however Stanford University has them in all of their laboratories . For ,safety, they can be calibrated to their most sensitive setting. E1 . 14 Lighting rows are perpendicular to windows . If parallel, the outside row could be dimmed for energy cost savings . E1 . 15 Occupancy sensors seem to have been omitted in the Art rooms . They should be added. 15550-3 87% should be the AFUE, not combustion efficiency. 07533 What is the total R-value of the roof insulation? Thank you very much for your attention to the above questions and requests for modifications to the spec. Please contact us at your earliest convenience. 3 M4 . 02 Combustion Air Heater. This is a 7 , 000 CFM device with a 2-stage motor. We would like to see a VFD for this motor, controlled through the DDC system. Volume of air intake should be modulated based on actual combustion air demand. 22 . 01 Is the dishwasher booster heater, provided by the Kitchen equipment supplier, gas-fired or electric? Gas is preferred. 21 . 04 We had previously discussed making these hot water tanks gas-fired. We are not happy about having electric DHW in the building, unless there really are no other reasonable alternatives. 15400 We had discussed using a high efficiency--residential-type DHW heater for the minimal hot water requirements of the high school during the summer. We also believe we can save some money by not installing a larger commercial model . Can we do this? 15410-6 What is the reasoning behind adding a 51h boiler to heat water for the indirect-fired tanks? As we previously ,discussed, our understanding is that, it is more efficient during the heating season to,,u,se the heat already generated by the space heating boilers . 15950-15 The computer specifications are not the most up-to-date, and should be upgraded as follows : Windows 98 or NT, 450 MHz, 64 .MB RAM, 4+ GB free memory, CD ROM, 20" color monitor. 15950 We want to have the capability of trend logging gas usage at the main meter, and we couldn' t find this in the spec. 15950 There is currently a redundancy of control points between the DDC and the custom boiler controls . We believe that a significant amount of money can be saved by not duplicating DDC control points at the boilers, and letting the boiler controls do what they were designed to do. Can we do this? 15950 There is a requirement of "documentation of proprietary services", and then a clause "limiting proprietary services . Is this consistent? 15950 There is a reference to the cabinet heaters set at 70 degrees and the unit ventilators set at 72 degrees . Shouldn' t these be at the same temperature? 15950-17 Upgrade back-up memory of global controller? 2 Northampton Energy Resources Commission Memorial Hall, 240 Main Street Northampton, MA 01060 (413) 587-1252 Fax: (413) 587-1303 MEMORANDUM TO: Michael McKeon, Kaestle Boos Architects Ernie Domingue, VanZelm Heywood & Shadford Robert Starr, H.

FROM: Northampton Energy Resources Commission RE: Northampton High School Mechanical-'& Electrical Specs DATE: January 25 , 1999 / The Northampton Energy Resources Commission (NERC) has had an opportunity to review the mechanical and electrical specification for the Northampton High School renovation and addition project . Overall we find the specifications to be very thorough and well documented, and we thank you for your attention to detail . We do have several questions, that we would like you to address before the pre-bidding conference later this week, as well as a few minor changes that will need to be made to the specifications . Please contact us regarding the following items . Section 15850-3 Unit Ventilators . Since we have the choice of three manufacturers, would it be possible for John Poudrier to be able to select the manufacturer of his choice? (since he will be maintaining them for the next 10 to 20 years) 15850-10 Electric Duct Heaters . Is there any way to eliminate this electric resistance heating? 15880-7 Duct Liner. Is this product anti-microbial, anti-fungal, and does it encapsulate the fiberglass particulate? 1 s ROOF It was voted and approved unanimously to remove the"new roof" from the specifications. Brett,John and Mike will look into the alternatives and report back to the Committee. Brett has spoken to the original roof installer and found it may be possible to repair and extend the warranty. The Committee will decide on what course of action to take on the roof at the next meeting. ASBESTOS The General Contractor is responsible for removing asbestos. The Committee is responsible for hiring a certified hygienist to monitor. HEIGHT OF HALL It will be impossible to make the ceiling in the side halls higher than 9'4" because of the amount of ductwork needed. The next meeting will be held on January 19, 1999 at 5:00 PM. Meeting adjourned at 7:10 PM. COUNCILOR Alex Ghiselin, councilor of Ward 5 spoke to the Committee. He was really thankful that we told the people what was going on and keeping our word He would like issues brought to the neighborhood as in the past. P1 3 SPECIFICATIONS Brett is waiting for the remaining specifications for his review and comments. Michael McKeon will get them to him as soon as possible. F Joseph Misterka wants to make sure everyone has time to review the specifications in time to add addendums if necessary before contractors bid on the project because change orders are expensive. HANDICAP ACCESSABILITY Tony met with Stravos on December 29`'to get their input on ways to make areas handicapped accessible. There were four(4) variances being sought. 1. A 28'ramp at the entrance to the auditorium. They will need a letter from the Historic Commission. 2. List all classrooms that are accessible per subject as internal doors in old section do not meet requirements. Would cost approximately$1,000 per door to make handicapped accessible. Some doors could be more. 3. Seating in auditorium to be equally dispersed in level area in back. 4. A variance is not going to be sought for the pressbox because it is for employees only and the cafeteria can be used for the handicapped. BOILER After checking specifications for the boiler and control systems,Brett said he would give Mike McKeon his comments in writing and a copy to Larry. CLERK OF THE WORKS Joseph Misterka reported that the Clerk of the Works position has been advertised and the Committee received 10 excellent applicants. They will be interviewing on Thursday and will have a candidate to recommend at the next meeting. Joseph Misterka,John Poudrier,Bob Starr and Mike Goggins are on this sub-committee. They have asked Frank Tudryn to sit on the interviews. PUBLIC ART COMMITTEE Mary will be meeting with the committee for the first time. The committee will walk through the school for one meeting. ADD ALTERNATE It was voted and approved unanimously to eliminate #8, upgrade HDPP drainage pipe to RCP,of the add alternate list. It was decided that there was no need to change existing pipes as they are only secondary feeder lines. 2 1 MINUTES OF THE NHS BUILDING COMMITTEE MEETING Held on January 5, 1999 Members attending: Larry Fink,Frank Tudryn,Ron Cooper,Martha McCormick,Lynn Posner Rice,Michael Goggins,Philip Ahearn,Neil Homstead,John Poudrier,Marjorie Richardson,Robin Barber,Pamela Hunter,Robert Starr and Merle Taylor.

MINUTES It was voted and approved to accept the Minutes of the Meeting of December 7, 1998 with the following correction: Page 2, 2'paragraph,should be Michael Bardsley not Beardsley. BILLS PAYABLE Joseph Misterka recommended payment of the following bills: Daily Hampshire Gazette 114.80 Kaestle Boos Assoc. 6,006.00 Kaestle Boos Assoc. 11,340.00' Kaestle Boos Assoc. 4,125.00 Kaestle Boos Assoc. 3,080.00' Union-News/Sunday Rep. 138.24 TOTAL $24,804.04 It was voted and approved to process the above bills payable warrant. -Joseph Misterka will not release the checks until he is certain that the architect has provided all services. GAS USAGE Larry inquired about the single source of gas. People are asking questions. When usage goes up,the gas company pipes in propane. Does that affect the heating system in any negative way? Brett reported that it would not be much difference in the maintenance of the equipment. LABOR PROJECT AGREEMENT It was voted and approved to use the Labor Harmony Clause.

As support material Include documentation from the school administration designating specific accessible rooms to be used on an as-needed basis. Accessible Routes--AAB Section 20.1 Corridor 0501 No variance is required since the corridor beyond the steps does not need to be accessible because the steps lead to areas/elements not required to be accessible-- locked storage rooms, an egress not designated as an HC rescue area, and a courtyard not intended for use by anyone. Corridor 2206 A variance is required for not providing access to upper seating and lobby. Due to structural constraints prohibiting an accessible egress, HC seating is proposed on main level so as to be near accessible egress. The room marked "Drama" is used for storage (and should be identified as such) and therefore does not need to be accessible. Auditorium & Little Theater Seating --AAB 14.4 spaces and companion seating Variances are required for wheelchair spa p g to be clustered in the back of the main level so as to be near accessible egress rather than dispersed throughout the theaters (and on upper level of Auditorium). Structural constraints determine location of accessible egresses. Submit documentation of such constraints in support of variance requests. No variance is required for access to stage which is achieved through corridor adjacent to theaters. Press Box for Multi-purpose Field. No variance is required if the Press Box is identified as employee-only space. In addition, the Administration should establish policy & procedures for everyone to use the electronically equipped cafeteria location instead of the Press Box on the occasion when there is someone with a mobility disability who cannot negotiate the Press Box. Please call if you have any questions or if I can be of further help. Good luck with the project.

MiliKowski Kaestle Boos Associates, Inc. P.O. Box 2590 New Britain, CT 06050 Dear Ms. Milikowski: I hope our meeting today was productive concerning the accessibility issues for the Northampton High School addition. A summary of our discussion follows. Entrances--AAB Section 25.1 Existing Front Main Entrance A variance is needed for not making this entrance accessible since AAB regulation 25.1 requires all public entrances to be accessible. It is proposed that the existing front entrance remain intact as requested by the local Historic Commission. An entrance 28 ft. to the west in the addition will be accessible via a ramp originating from the bottom of the front steps, as shown on the site layout plan, and ending in the entrance lobby. Include a letter from the local Historic Commission as support material with the variance request. Non-compliant Front Entrance east of existina main entrance No variance is required for being inaccessible due to steps/non-compliant ramp if, as discussed, this door becomes an egress by not having exterior hardware. Rear Entrance at Stair D1 No variance is required for being inaccessible if usage of this entrance is officially restricted to employees only and identified as such. Doors and Doorways--AAB Section 26. 1, 26.6.3 A variance is required for all doors that are not accessible along accessible routes. Since all such doors not having sufficient wheelchair clearance on the puii side of the door are not accessible, then two options can be pursued, given the structural constraints. 1) Relocate such doors flush with interior classroom walls (and in some 691 South East Street • Amherst, Massachusetts 01002 • (413) 256-0473 V/TDD • FAX (413) 256-0190 • (800) 442-1185 Additions and Renovations Northampton High School Northampton,MA KAESTLE BOOS KB #96079 ASSOCIATES,INC. ARCHITECTS Questions • Accessibility to the Upper Balcony is restricted due to existing stairs (see Compliance Alternative for description). Due to this restriction, handicapped seating will not be provided at the Upper Balcony, but will be included at the main level seating area for the total number of seats in both areas. Will this require a compliance alternative also? • Handicapped seating spaces are provided at the rear of the auditorium only, due to the slope of the existing floor slab and space restraints at the front of the auditorium. Also, handicapped egress is provided only at the rear of the auditorium. Is this acceptable? • Will a handicapped lift be required at the front of the stage if accessibility to the stage is achieved by leaving the auditorium? This also applies to the Little Theater. Space restraints are an issue here and considerable demolition will occur at the Little Theater if a lift is required. • There is a press box included at the top of the new grandstands, located at the multi- purpose field. Is accessibility to the press box required if an alternate location of the same facility is provided at the Cafeteria in Lower Level Area A? The field is able to be viewed from this location. Providing access would be extremely cost prohibitive (approx. $75,000 for the elevator, only $30,000 for the press box.) \\NTSERVER2\DATA\Northampton\1998\High School\Notes\AABvariances.doc Additions and Renovations Northampton High School Northampton, HA KAESTLE BOOS KB #96079 N R C H ITES,INC. ARCH ITTECTS W U Variance for Floor Surfaces - Section 29.1, 29.2.3 Corridor 0501 There is an existing set of stairs at Corridor 0501. The area accessed from this corridor is storage and is used only by custodial staff. Egress is not required in this direction and an area of rescue assistance is provided at Stair E I. A variance is requested to maintain a change in level in the existing corridor with access only required by custodial staff to a non-programmatic space. Passage 2206 Passage 2206 includes an existing set of stairs. Due to constraints of existing construction it is not feasible to install a ramp to the Upper Lobby area. The required width of the passage is 6'-0" and is considered a corridor, not a stair. Installation of an inclined wheelchair lift would impede on the required width of the corridor for egress purposes. Furthermore, two means of egress are required from this area and a wheelchair lift is not considered an accessible means of egress by 780 CMR, Section 1007.4. A variance is requested to allow a change in level that includes an existing stair. Handicapped accessible seating is provided at the main level Auditorium based on the total number of seats including the Balcony. Handicapped accessible egress is provided from the main level. There are no programmatic spaces at the Upper Balcony area accessed from Passage 2206. \\NTSERVER2\DATA\Northampton\199Migh School\Notes\AABvarlances.doc ` Additions and Renovations Northampton High School Northampton, MA KAESTLE eoos KB #96079 ww U ASSOCIATES,INC.

There is a 60" clear floor space located on the pull side of the door, but a minimum of 18" pull side clearance is not provided. There is approximately 8" on the pull side of the door to an adjacent wall. Constraints of the existing wall construction include structural concrete columns and masonry walls supported by suspended structural lintels above the lockers. Modifying the door pockets is largely impossible due the existing concrete columns adjacent to the pocket. Removing the masonry walls suspended above the lockers would start to impact the structural integrity of the building. This demolition only occurs in a few areas in order to provide accessibility to a newly created room. A variance is requested to allow non-compliance of pull side clearance on existing doors to remain, as listed above. At least one classroom per program has been provided with a handicapped accessible entrance. Classroom doors to the corridor that are not required to be fire rated do not have closers. \\NTSERVER2\DATA\Northamp ton\1998Viigh School\Notes\AABvariances.doc Additions and Renovations Northampton High School —° Northampton, MA KAESTLE BOOS KB #96079 ASSOCITEC D n n ARCHITECTS CTS Variance for Entrances - Section 25.1 Entrance at Stair D 1 A new exterior stair is provided at the entrance of Stair DI due to changes in grading. Stair DI is an existing stair with interior steps from the exterior door up to the lower level. Due to the constraints of existing construction, it is not feasible to construct a ramp on the interior of the stair enclosure. Providing a handicapped lift would impede on the required width of the stair for egress purposes. A variance is requested to allow a non-handicapped entrance to be used in this area. This entrance will be used primarily for staff and custodial as the only entrance at the rear of the building. Handicapped parking is provided at two main entrances to the building. There are a total of 4 accessible entrances to the building. All other entrances are not provided with exterior hardware. Entrance at Vestibule 1204 The monumental exterior stairs leading to the Auditorium Vestibule are existing. Due to the constraints of the existing grade in this area, the existing stairs are to remain and a new handicapped accessible ramp is provided leading from the bottom of the existing stairs to a separate entrance adjacent to the Auditorium Lobby. A variance is requested to allow this alternative accessible route and entrance adjacent to the Auditorium Lobby. The main entrance to the building is also accessible. \\NTSERVER2\DATA\Notthampton\1998\High School\Notes\AABvariances.doc I The Commonwealth of Massachusetts ARCHITECTURAL ACCESS BOARD One Ashburton Place - Room 1310 Boston, Massachusetts 02108 ARGEO PAUL CELLUCCI (617) 727-0660 GOVERNOR KATHLEEN M.

She informed me that Mr. Michael Festa, the Compliance Jamie L.DiPinto Officer who reviewed the set of documents for accessibility compliance, no longer works in that office. She added that the AAB only reviewed the documents as a courtesy to the Department of Vincent R.Amrhein Education and that they were not notified of this responsibility by that department. The AAB is Traci H.Milikowski no longer reviewing documents due to the lack of staff. A standard form letter explaining this issue is being drafted, however, Ms. Ryan did not expect that she could send this to me in the near future. Ms. Ryan was able to answer a few questions I had regarding the 1996 Rules and Regulations, but reiterated that the review of this set of documents will not be completed. Based on the comments in the attached letter from the AAB, variances will be required for the first three items. The toilet rooms noted in Item No. 4 are existing rooms to remain, are not included in the plumbing fixture count,and are not required to be handicapped accessible. Due to the nature of the existing building and non-accessible portions thereof,we will review the CONNECTICUT Code Information Plans with the Local Building Official, Mr. Anthony Patillo, for code compliance and i particular, handicapped egress from the building.

FF&E Budget Report: • The FF&E Sub-Committee meeting on October 21, 1998 with the"Department Heads"was successful. The Teachers now understand what is involved in making a priority list. They were asked to prioritize their equipment needs list. These lists will be sent to Kaestle Boos Associates by the first week of November so that the Budget can be revised. The following are answers to questions that KBA was asked to review: • Attached is a list of exterior athletic equipment that is included in the $25,000 budget pricing. This list was requested at the Sub-Committee meeting. • Mr.Richard Winnick is concerned about the Media Center bookstacks blocking the view of the upper left-hand table on the right side of the bookstacks from the circulation desk in case there is a fight. He has asked KBA to review the option of turning the bookstacks on an angle(see attached floor plan sketch). KBA has the following concerns: • Keeping the required circulation around the bookstacks while rotating them,you will lose 7 bookstacks. This will decrease the required number of bookstacks recommended by the state. • When the Media Center Specialist is helping students in the Reference and Computer area,He/She will not be able to observe students in the bookstack area. • Rotating the bookstacks is only beneficial if the Media Center Specialist is constantly at the circulation desk and does not move throughout the Media Center. 2 Plan Updates • Met with Frank Tudryn,Tom Kress,Diane Dostal and Albert Zaralban re Culinary Arts—see attached • See attached Library/Media Ctr plan. • See attached plan change to Child Care K:\Northampton\1998\High Schooi\Notes\Arch'Report1026.doc Page 1 of Mike McKeon should"voice-over" an explanation of the planned-renovations video made by KBA. Marjorie Richardson suggested that Mike's video be preceeded by the one made by NHS students. Pam was not pleased with how that student-produced video now ends,with a money pitch from David Duseau. Marjorie suggested turning off the video at the point that Duseau came on to ask for donations. Pam vetoed that idea. Pam suggested that Joe Misterka be present to answer questions about the overall budget for the project. Larry agreed that Joe Misterka was the most respected"budget man"in the area. Maybe Frank Tudryn should have students willing to lead voters on tours of the building when the formal presentation is over. The meeting was adjourned at 7:00pm. Respectfully submitted, Marjorie Richardson (substituting for Peggy Leducer) planned electronics repair shop. Robin Barber said that photography in the future will be dominated by digital graphics and so a traditional photography dark room may not be a priority. Martha was not sure how to proceed. There may be a need to spend$60,000-$100,000. to upgrade the culinary arts Clab(classroom and laboratory).KBA is asking for the right to authorize hiring a food service consultant to redesign the proposed new Clab. Pam Hunter asked if we would be duplicating what is taught,as culinary arts,at Smith Vocational High School? Larry Fink recommended that KBA visit Smith Voke and report back how the new Clab at NHS is different from what goes on at Smith Voke. Before we spend $5,000. for a consultant on food services, Ron Cooper should go with Frank and Dianne, to make sure that the culinary arts plans for NHS do not copy the ones at Smith Voke. Lary explained that when the renovation project was first planned,the School Department developed an educational plan to house a specific curriculum. The School Committee approved the plan put forth by the School administration and high school staff.Now,the SBAB will ask Mike McKeon to explain how his plans are wedded to the modem educational program. Mike McKeon said that the SBAB issued a leter,around September 17, 1998, describing how to proceed with plans that affect the original cost-estimates. If the costs go far beyond what was submitted with the first schematic drawings,then one needs to be ready to review that cost change at the time of the projects audit. The audit is done shortly after the building is completed.Mike may be able to submit a revised form"F",before the project is"sent out for bids". John Poudrier asked where the new custodial storage rooms were located. Mike McKeon said that there would be new janitorial storage rooms, a chemical dispensing station and new floor sinks. Joseph Misterka will investigate the use of Fikers school for storage and to house Eric Gagne's operation_ Joe will report back to us on the matter. Mike McKeon pointed to a hard-paper-mounted drawing of the new,top floor, Art department. The two largest rooms are both handicapped accessible. If KBA determines that one may not be, then Tony Patillo needs to get a variance for that inaccessible area. Joe Misterka asked Mike McKeon if the use of granite is being planned for the renovation. Mike responded that presently, there is no granite on the site. There is an"add-alternate" item to change the curbed parts of the parking lot from bituminous surface to concrete. In response to the last part of Mike McKeon's presentation: 1. we need to meet around Oct.26th, to finalize what we want KBA to finish work on. 2.Frank Tudiyn, Martha McCormick,Robin Barber,and Peter Shaughnessy need to meet with the new principal,Ms. Stone, to get her input on how the curriculum changes are being developed, in relation to this project. 3.We should meet on Nov. 10, 1998,at 5 pm,to review the Nov.3, 1998 override vote by the voters. 4.In response to the$2,800. request to do an infra-red scan of the NHS roof; Pam Hunter moved that we take a suggestion made by John Livermore(of the Energy Resources Commission),and have KBA arrange for the roof scan to be done. Motion passed unanimously. 5.About the guard rail design, Mike passed around a drawing that showed an iron-hammered-metal railing, (see enclosure) to be placed at public entrances. Pam Hunter moved its adoption. Motion passed unanimously. Lary called on Pam Hunter for a discussion of our special public meeting,at 7 pm,in the cafeteria of Northampton High School,scheduled for Monday,October 19, 1998. Pam preferred to call it an"information night" rather than a"forum". She will probably make an announcement of it at the next City Council meeting. She proposed that Lary Fink chair the meeting,and that members of the Building Committee be present to hand out the Information sheet we have prepared.Also,that KBA be represented by Mike McKeon (he will be there), who may need a van in order to bring with him all of the display boards of floor plans and FF&E materials,to be displayed around the room. Dick Webb should attend (he may not be able to) and explain the athletic fields. The chairs of sub-committees might want to speak on the challenges they faced. 1 1 Tuesday 13 October 1998 Minutes of Meeting of the Northampton High School Buildig Committee Larry Fink called the meeting to order at 5:OOpm. Members present included:Marjorie Richardson,Bob Starr,Ron Cooper,Michael Ahern,Robin Barber,John Poudrier,Martha McCormick,Merle L.Taylor,Lynn Posner Rice,Neil Homstead, Mike Goggins,Peter Shaughnessy,and Joseph Misterka. Ex-officio members present were Mary Kaspar and Anthony Patillo. Mile McKeon represented Kaestle-Boos and Associates. Additions or corrections: Marjorie Richardson mentioned that in last meeting's minutes, she is noted as having "abstained". She did not abstain on the whole issue of the Add-Altemates listing,but abstained only on the part conceming whether or not to have window seats in the new foyer of NHS. Larry Fink asked Joe Misterka if he had any correspondence to report. Joe responded that he has recently attended meetings on public school financing. He and Larry Fink believe that President Clinton will propose more money to be sent to the States for improving school buildings. Larry called on Martha McCormick to report on the FFand E(furniture,finishes,and electricals)sub-committee. Martha reported that her sub-committee met with Casey, from KBA,to discuss a list of equipment. Different departments at NHS had submitted lists of equipment that they needed. The combined"wish lists" pushed the expenses over the originally-set limits. Martha will ask Department heads to prioritize their lists. Robin Barber said they had not had enough time to do this. Peter Shaughnessy said the sciences were more than willing to explain their choices.Mary Kasper said that some committee members had the wrong time for the meeting,and not all of them were aware that the new lists moved the costs of FF&E past the$750,000. that was in the general budget. Joe Misterka said that the City will go for a construction bid and when that happens, we should have a priority list of the FF&E equipment, since we will not know how much is available,until the building costs are fatly known. Lynn Posner Rice wondered if Casey would produce an inventory list of what equipment, presently at NHS,could still be used after the renovation and expansion is done? Merle Taylor speculated that to have a priority list soon,would be an exercise in futility since that list will change,as the money available for FF&E changes. Martha McCormick agreed to have some sort of priority list ready for our next regular meeting in two weeks. Lary called upon Marjorie Richardson and Bob Starr to report on the Mechanical and Electrical sub-committee. Marjorie reported a phone conversation with Mayor Mary Ford's Assistant', in which the assistant said that the Gas company had agreed to install a gas pipe line,undergound at NHS,at its own expense. This was in response to a question Larry had asked Marjorie last month. Larry explained to the rest of the members that in order to put in a detention-drainage pond near the athletic fields, and to repair a problem that should have been corrected by the Department of Public Works, this Building Committee,was struggling with these undergound pipes issues. Mike McKeon pointed out that there may be two new pipes in question, and did the Mayor's assistant specify which pipe would be taken care of by the Gas Company? Marjorie agreed to contact John Livermore and to get the names of his contacts at the Gas Company,so that two letters could be sent to Larry Fink. One letter would specify the gas lines to be taken care of at the Gras Company's expense; and the other letter would be to clarify that the the$50,000-$60,000 rebate that the Gas Company has promised us, will be sent to the NHS Building Committee,and not to any other group. Once that is done, the M&E sub-committee does not expect to have any future meetings. Lary called on Ron Cooper to report on the sub-committee on temporary food services. Ron reported that the Board of Health has agreed to (current food service provider) John Feeney's plan to provide lunches at NHS for one academic year,during the renovations. A drawing of the potential food service venue(the lobby of the main auditorium)was sent from KBA. A motion to adopt John Feeney's lunch service plans was passed unanimously. Lang turned the meeting over to Mike McKeon from KBA who reviewed the hand-out,KB#96079,which starts with the problem with the FF&E lists. The FF&E budget was for$750,000. but the departmental lists are for more than $912,000. See enclosures. There was a meeting on the technology needs and Michael pointed out that wiring for one modular wall will allow it to be used as a student electronics lab. In another area, one teacher can can use a classroom that handles editing and filming. Martha McCormick asked if the photo dark room could be moved from its current location into the newly- P.O.

F&E Budget Report: • The specific equipment needs were added to the budget after meeting with staff members on September 23, 1998. • The current budget was presented to the Sub-Committee on September 30, 1998,which is currently at$912,000.00. • The Sub-Committee has agreed with KBA recommendation that each department prioritize their original lists(1. Curriculum must,2. Curriculum bonus,3.Do not necessarily need). • A memo was sent to the staff from the Sub-Committee to do so and send the new lists to KBA by October 9, 1998. KBA is still waiting receipt of these lists from each department. • When these lists are received,the budget will be revised according to the priorities and presented to the Sub-Committee for review and final approval. • Upon approval,the budget will then be presented to the Building Committee,at their next meeting, for approval to prepare final drawings and specifications for Bid. Also,at this time a copy of the Front End Bid Documents will be given to the City and the Building Committee for review and approval. 1. Plan Updates • Met with Frank Tudryn,Tom Kress,Eric Gagne,Wes Pettitt and Scott Goodrich to review Technology Education department plans.The following was agreed to: 1. Modular Tech.Lab layout is accepted as designed although some module types (FF&E) may change.Hand tool storage to be included at end of"project platform"(keep it on "hands on"side of movable wall). 2. Electronics lab to be outfitted as a student Electronics Lab rather that a "electronics repair shop".This essentially means work stations along each side wall. 3. The Cadd lab is accepted as shown. 4. The TV/Audio Production lab is accepted as redesigned but with the incorporation of the storage room at the top of the ramp into the Construction Lab Storage Room (air compressor to be located here). 5. The Construction Lab will require a finish room(with vision panel to office). The dust collection system will be relocated (behind the school) and re-used.A fine particle filter will be added to the room.Mr. Kress will review the equipment layout so that the dust collection duct and K:\Northampton\1998\High School\Notes\Arch'Report 1013.doc Page I of2 Page 6 of 6 Massachusetts Architectural Access Board. Where a hardship exists with respect to strict compliance with the Regulation, the design of related building features being altered should include features intended to compensate for the noncomplying feature. The scope of this review has not included a survey of existing conditions and the extent of their compliance with the regulation's requirements for new construction. Such a survey will be required to identify noncomplying building features and make possible an appeal for a variance to permit those conditions to remain. If you or your client have any questions concerning this analysis of the access regulation or require further details concerning specific issues, please do not hesitate to contact me. Very truly yours Harold R. Cutler Harold R. Cutler 14091" x Page 5 of 6 applicable) and lines of sight comparable to those for members of the general public. In addition, a similar number of seats would be required to be aisle seats without arms. Access to Performing Areas 521 CMR 14.6 requires that an accessible route connect wheelchair seating locations with performing areas including stages, dressing rooms, locker rooms and other spaces used by performers. A wheel chair lift is specifically allowed for access to the stage but might not be acceptable as part of other accessible routes. Box Office Ticket Counters A box office, if provided, is required to be on an accessible route and to have an accessible counter. The accessible counter is required to be at least 36 inches long, not higher than 36 inches and arranged with sufficient clear floor area in front of the counter and arranged to satisfy reach range limitations given in 521 CMR 6.5 and 6.6. Dressing Rooms 521 CMR 33.2 requires that not less than one dressing room in each cluster of rooms, if provided, be accessible. The details of requirements for an accessible dressing room are provided in 521 CMR 33.0. Public Toilet Rooms 521 CMR contains criteria for the number, location and arrangement of public toilet rooms associated with a place of assembly. All renovations and construction in public toilet rooms should be made in compliance with that section. Other Considerations 521 CMR 25.1 requires that all public entrances of a building shall be accessible. This requirement will require upgrading of all existing public entrances or variances from the Regulation to permit those public entrances to remain inaccessible. All design work should be based on the requirements of the Regulation or providing alternatives to strict compliance that can be justified in the variance process. Such alternatives will be important as compensation for features which would be difficult to bring into strict compliance with the Regulation due to existing site or interior conditions. Conclusions The Regulations of the MA Architectural Access Board require that all new work in an existing building being altered or renovated be performed in compliance with the requirements for new construction. In this particular project, the cost of the proposed renovations and additions are such that complete compliance of the existing building with the current access regulations is required. However, it is unlikely that complete compliance can be achieved. For existing conditions which can not be upgraded to strict compliance, variance must be obtained from the 14/09/98 Page 4 of 6 the presence of a chair.) • Standard clear floor spaces shall be provided at each seating space in accordance with 521 CMR 5, Definitions. • Clear floor space shall not overlap knee space by more than 19 inches. • Knee clearances for seating at tables and counters shall be at least 27" high, 30" wide and 19" deep. * The tops of accessible tables and counters shall be from 28 to 34 inches above the finished floor. " At least one check out lane at each check out area shall have a counter a minimum of 36 inches long and a maximum of 36 inches high. * Security devices shall not prevent entry or egress of persons in wheelchairs. * Security gates shall have a minimum clear width of 32". • Card catalogs shall be accessible in accordance with criteria in 521 CMR 12.2.5. • Aisles within stack areas shall have a minimum clear width of 36" and 42" where possible. Shelf height in stack areas is unrestricted. Kitchens Kitchens in classrooms shall comply with the requirements of 521 CMR 32. Sinks, Counters and other Work Areas At least 5% of each sink, counter and other work area in a classroom of laboratory shall be accessible in accordance with 521 CMR 12.4 Places of Assembly (521 CMR 14) Accessible Seating Several requirements of Section 521 CMR 14 relate to accessible seating in auditoriums and lecture halls. The two most critical of those sections are 521 CMR 14.2, Number of Accessible Seats, and 521 CMR 14.4 Placement of Wheelchair Spaces. In a theatre required to be upgraded to full compliance with 521 CMR, wheelchair spaces would be required at a rate of 6 for the first 500 seats of a theater and one additional position for each additional 100 seats. The accessible spaces are required by 521 CMR 14.4.1 to be distributed proportionally so as to provide a choice of admission prices (if 14/09/98 Page 3 of 6 led us to the conclusion that work being performed would amount to more than 30% of the value of the existing building. That conclusion was based on an estimated cost for the renovations and additions of$18,100,000 compared to a building value of$22,450,000. Even with deduction of some project costs which are exempted by the Regulation from this analysis, we concluded that the cost could still not be reduced below 30% of the value of the building. In this case, therefore, the project will fall into Category B above. In Category B, the new work being performed would have to comply with the regulations and all existing noncomplying features would have to be upgraded to compliance unless permitted by formal variance to remain in noncompliance. The MAAAB will entertain variances from strict compliance only if there is a high cost-to-benefit ratio. The following discussion reviews some of the technical considerations that would apply to a full upgrading of the building. Specific Technical Issues Section 521 CMR 12.00 and 14.00 contain general requirements for accessibility of educational and assembly facilities respectively. Other sections of 521 CMR contain requirements affecting specific features of this site and building including: • Curb cuts* Public toilet rooms • Walkways* Dressing rooms • Parking and loading zones* Tables and seating • Ramps* Drinking fountains • Entrances* Public telephones • Doors and Doorways* Controls • Stairs* Alarms • Elevators and other lifts* Signage • Floor surfaces The requirements of 521 CMR with respect to the fundamental design characteristics of educational and assembly facilities are discussed below. Educational Facilities (521 CMR 12) Libraries All public areas of a library including but not limited to, reading and study areas, stacks, reference rooms and reserve areas shall be accessible. Specific characteristics of such areas shall be as follows- * Five percent of tables, study carrels, computer work stations or fixed seating shall be accessible and on an accessible route. • Access aisles between tables and study carrels shall have a clear width of 36 inches. Seating shall not overlap the access aisle (Note: the building code requires that access aisles be measured at 19 inches from the edge of tables that have moveable chairs to take into account 14/09/98 Page 2 of 6 Proposed Renovations The project will involve renovations in essentially all areas of the existing complex. A moderate percentage of the work will involve replacement or upgrading of the existing mechanical and electrical systems of the building and installation of automatic sprinkler protection. The additions to the building are also taken into account in the analysis of the applicability of the MAAAB regulations to the facility. Massachusetts AAB Regulations The regulations of the Massachusetts Architectural Access Board are found in 521 Code of Massachusetts Regulations (521 CMR). The latest edition of those regulations is dated March 6, 1998. That edition will become effective on September 6, 1998. 521 CMR is applicable to those areas of a building in which educational or other services are available to the public. Section 521 CMR 12.00 is specifically applicable to educational facilities. Two sections of the regulation combine to determine the extent of upgrading of the space required. That determination is based on the dollar value of the work being done in the building and also on the full and fair cash value of the building. The formulas from Section 521 CMR 3.3 for determining the applicability of the regulations are as follow: A. If the work being performed amounts to less than 30% of the 100% equalized valuation of the building and 1. if the cost of the work is less than $100,000, only that portion of the work being performed is required to comply with the regulations. 2. if the cost of the work is $100,000 or more, then that portion of the work being performed is required to comply and an accessible entrance and an accessible toilet, telephone and drinking fountain (if public toilets, telephones and drinking fountains are provided) shall also be provided. B. If the cost of the work being performed or the cost of an addition amounts to more than 30% of the 100% equalized assessed value of the building, the entire facility must be made to comply with the regulations. Section 521 CMR 3.5 specifies that the cost of the work being performed in any 36 month period is to be accumulated as a total cost when applying the above rules. The regulations appears to require that the cost of an addition be included in the "work being performed".

Consulting Fire Protection Engineer 165 Landham Road Sudbury, MA 01776 -3156 Voice & fax 978-443-7088 Email hcutlercfpe@earthlink.net September 4, 1998 P/N 797 Peter Frothingham 131A State Street Northampton, MA 01060-2243 PRELIMINARY Dear Peter: Subject: Summary of Basic Access Code Considerations Northampton High School Northampton, MA This letter will summarize my preliminary analysis of the requirements of the accessibility regulations of the MA Architectural Access Board (521 CMR) applicable to renovation of the existing Northampton High School as a result of the work proposed in that building. This letter is based upon my review of the "Coordination Plans" dated March 30, 1998 prepared by Kaestle Boos Associates, Inc., our discussions of those plans prior to September 10 and our meeting on September 10 with Northampton Zoning Enforcement Officer Anthony Patillo and Mike McKeon of Kaestle Boos Associates. This letter does not include a review the applicability of the Americans with Disabilities Act Accessibility Guidelines (ADAAG). As for 521 CMR, the ADAAG require access to locations where the public is offered products or services including educational facilities. However, the ADAAG also include accessibility requirements for places of employment and might have impact on spaces not subject to 521 CMR. I do believe the package of improvements which are required by 521 CMR will satisfy the essential requirements of the ADAAG. In this type of facility, many of the remaining ADAAG requirements for places of employment would normally be satisfied by the level of accessibility required for the educational areas. 14/09/98 Peter Frothingham, PFA Page 11 September 4, 1998 energy conservation improvements are required to confirm compliance with respect to those requirements. The New Construction The proposed fire wall between the Band Room area and Building 1 appears to be arranged as a "panel wall" and is not explicitly allowed by the MSBC as a building separation wall. A variance from the building code is required to permit that specific design. A proposed open stair that also has been considered a means of egress is not permitted to serve that function. That stair will be enclosed as required for an exit stair. The interior finish for exits in assembly and educational spaces and for exit access corridors in assembly spaces is required to be Class A. If you have any questions concerning this information, please do not hesitate to contact me. Very truly yours Harold R. Cutler Peter Frothingham, PFA Page 10 September 4, 1998 A note concerning interior finish on Drawing R1.00 indicates interior finish in exits of buildings of Use Group A and E is permitted to be Class B. That is not correct. MSBC Table 803.4 indicates such spaces require Class A interior finish. Similarly, that note indicates the interior finish in corridors of Use Group A buildings may be Class B. MSBC Table 803 . 4 indicates such corridors require Class A interior finish. Conclusions The Existing Building The existing Buildings 2 and 3 are not in compliance with the current code with respect to the height and area limitations. Without other factors such as the sprinklering of the building or subdivision of the existing building, any addition to the building would have to be separated from the existing building by a fire wall. The proposed use of panel type fire walls for subdivision of the existing complex into two separate buildings (Buildings 2 and 3) should be acceptable as compliance alternatives to strict compliance with requirements for free standing fire walls. The installation of the sprinkler system in the building as wells as the limited amounts of fuel in the buildings should limit fire size, intensity and duration to levels which do not threaten those walls. Existing systems, assemblies or materials may be repaired with similar materials. New or replacement features of the building are required to comply with the code for new construction to the maximum extent practical. Means of egress features such as exit signs and lighting and means of egress lighting are required to comply with the code provisions for new construction. Installation of new sprinkler and fire alarm systems will be required on the basis of the substantial nature of the proposed renovations. A sprinkler system would justify use of some building features allowed in new buildings such as open stairs. The limited seismic requirements applicable to the existing building prohibit alterations to the existing building' s structure that would reduce the lateral load resistance of the building. Additional reviews of the Code' s requirements concerning Peter Frothingham, PFA Page 9 September 4, 1998 If a building is assigned to Seismic Hazard Category 2, it is also required to comply with Section 3408.3 .5. It is also required to be investigated for special earthquake hazards as defined in Section 3408. 6.3 including parapets, masonry walls, and precast concrete structural elements. If such hazards are found, they are required to be corrected in accordance with the provisions of Section 3408.6 .3 . Information reported at our meeting on September 10 indicates all work proposed within the existing complex will cost $9, 000,000 while the existing complex is valued at $22,450,000 . The project, therefore, falls into Seismic Hazard Category 1 and is subject to only the minimal requirements of MSBC Section 3408. 3 .5 . Code Requirements for Buildings 1 and the Band Room A limited review of the plans for the new construction (Building 1 and the Band Room area) indicates the following. The fire wall planned to separate Building 1 from the Band Room addition is not a structurally free standing fire wall. Fire ratings are proposed for the adjacent structure in both Building 1 and the Band Room area. The architect has indicated that wall should be considered to be a "panel wall" fire wall at that location. That type of fire wall does not explicitly satisfy the code requirements for a structurally freestanding wall and could only be permitted as a variance from the code. The means of egress for the new portion of the complex appears to be appropriately arranged and have sufficient egress capacity for the anticipated occupant load except as noted below. Stair No. Al which connects the main entrance area of the gymnasium on the Main Level with the main doors to exterior is open to the Lower Level. Such open stairs are prohibited unless arranged in accordance with code requirements for such a feature in a new building. MSBC Section 713.3, Exception 2, does permit an unenclosed floor opening connecting not more than two levels of a building when certain conditions are satisfied. One condition is that the open stair may not serve as a required exit. The documentation of occupant loads and egress capacities of the building provided on Drawings R1 . 02 and R1 . 03 indicates the open stair at the gymnasium entrance has been considered to be an exit stair. Either that stair must be enclosed to be permitted to be an exit stair or the availability of alternative egress capacity must be identified. Peter Frothingham, PFA Page 8 ' September 4, 1998 extent practical" . The detailed requirements for a manual and automatic fire alarm systems are provided in MSBC Sections 917.0 and 918. 0. Item (8) - Floor Openings I find no existing unenclosed stairs. HVAC and Electrical Systems As for all systems, the existing HVAC and electrical systems may be maintained as is, improved on a piece-by-piece basis or replaced in a manner in compliance with the code for new construction to the fullest extent practical. When replaced on a piece-by-piece basis, new equipment would have to comply with the code for new equipment but there would be no obligation to improve the system as a whole to comply with the current code. Plumbing System The MA Plumbing Code has few requirements that are retroactive. With respect to fixture counts, I am unaware of any requirements for retroactive improvements unless the occupant load of the building is being increased. Structural System Improvements The extent of improvement of the seismic resistance of the structure of an existing building depends upon the "seismic hazard category" of the building as defined in MSBC Section 3408. 1 and Table No. 3408.1 . The existing building, in which there is no change of occupancy or occupant load proposed, will fall into Seismic Hazard Category 1 or 2, depending upon the cost of renovations to the building. If the cost of renovations exceeds 50% of the assessed valuation of the building, the building is assigned to Seismic Hazard Category 2 . If the cost is less than or equal to 50% of the assessed valuation of the building, it is assigned to Seismic Hazard Category 1 . (See Table 3408. 1, Notes 2 and 3 . ) If a building is assigned to Seismic Hazard Category 1, it is simply required to comply with the requirements of MSBC Section 3408. 3 . 5 . That section prohibits alterations to an existing l building' s structure that would reduce the lateral load resistance of the building. Specific criteria for acceptance of alterations are provided in Section 3408.3.5. Peter Frothingham, PFA Page 7 September 4, 1998 ' Item (6) - Fire Walls There are no existing fire walls (that is, structurally free- standing, fire rated walls) which subdivide this complex. The plans appear to indicate fire separation walls or fire partitions are provided surrounding some of the assembly spaces. Because of the addition of the Band Room and adjacent spaces to Building 2, the architect has indicated the existing complex together with the Band Room area will be subdivided into two separate buildings. The separations between the buildings are to be made with three sections of "two hour fire separation (fire area) " walls (See Plans R1 . 02, R1. 03 and R1 . 04 . ) . A technical code problem with this scheme is that the existing fire separation walls do not qualify as fire walls because they are not structurally freestanding. A fire wall is required to be structurally freestanding upon collapse of the building on either side of the wall. The walls proposed to serve as building separation walls are supported on the structure of the two buildings separated and can not, therefore, be considered to be fire walls . Under that strict interpretation, the existing building could not be expanded by the addition of the band room. The use of a fire separation wall supported on a fire resistive structure as a fire wall is a concept which is accepted by the insurance industry. That acceptance is based on the fact that the noncombustible, fire resistive structure is not expected to collapse despite burn-out of the contents of the building. The fire separation wall supported on that structure would, therefore, be expected to remain in place and perform effectively as a fire wall. Such walls are labelled "panel fire walls" . The acceptance of the fire separation walls supported by the existing fire resistive structure could be permitted by the local building official as a compliance alternative to strict code compliance under the provisions of MSBC Section 3406.0 . Item ( 7 ) - Fire Protection Systems Automatic sprinkler protection are required in this building on the basis of the provisions of MSBC Section 3404 . 11 and 3404 . 12 and the requirements of the code for sprinklers in new assembly buildings in Section 904 .2 . Because of the extent of renovations and addition proposed, a completely new fire alarm system will probably be required. As a new system in an existing building, it will be required to comply with the code requirements for new construction "to the fullest Peter Frothingham, PFA Page 6 September '4, 1998 • Use as a mixed use building having Assembly (Use Groups A-1, A-3) , Educational (Use Group E) and Business (Use Group B) uses. • A footprint area of approximately 56,955 sf divided into 39,580 sf for Building °2 and 17,375 sf for Building 3 . • Reinforced concrete construction probably able to be qualified as Type 2A, fire resistive, or better construction for Building 2 . • Unprotected, noncombustible construction considered to be Type 2C, construction for Building 3 . • No automatic sprinklers. • A high percentage of the building facing driveways or parking areas which provide access for fire fighting operations. Building No. 2 as it exists does not satisfy the height and area limitations of the code because a building with the above characteristics would be limited to an area of less than or equal to 30,523 sf, the limitation for an unsprinklered, three story, Use Group A-1 building of Type 2A construction with approximately 54% perimeter access. Building No. 3 as it exists also does not satisfy the height and area limitations of the code because a building with characteristics identified above would be limited to an area of less than or equal to 6, 720 sf, the limitation for an unsprinklered, three story, Use Group A-3 building of Type 2c construction with approximately less than 25% perimeter access. Under these circumstances, MSBC Section 3404.9 would prohibit any additions to either Building 2 or 3. The allowable areas of these buildings will be increased by the installation of automatic sprinklers. That approach is being taken to the addition of approximately 6, 000 sf to Building 2 . An "addition" could also be constructed as a separate building abutting and connected to the existing building if separated from the existing building by a properly arranged fire wall. That is the approach chosen for the construction of Building 1 adjacent to Building 2 . Peter Frothinghdm, PFA Page 5 September 4, 1998 MSBC Section 3408 contains the Code ' s structural requirements for existing buildings. Section 3408.2 requires a structural evaluation of an existing building which includes a field evaluation, structural analysis, field observations during construction and necessary geotechnical explorations. The scope and cost of the proposed renovations and additions is such that some upgrading of the existing structure is likely to be required. Detailed criteria for structural repairs and upgrading provided in MSBC Section 3408. 0 which might be applicable to the building are discussed below and should be reviewed in detail with the project ' s structural engineer. Specific Considerations The impacts of the above requirements except those related to energy conservation are discussed below. Items 1 2 3 and 4 - Means of Egress The existing means of egress system provides multiple paths from all levels of the building using enclosed stairs and doors directly to the exterior. The requirement for adequate egress capacity is satisfied by the existing means of egress and is not compromised by the proposed construction. The MSBC does intend that the renovated building comply with the requirements of the code for new construction concerning exit signs and lighting. The plan set available does not include plans for exit signs and lighting. No other improvements of the existing means of egress for the building are required unless deficiencies are specifically cited by the authorities having jurisdiction. Modifications of the means of egress such as the elimination of a door or other reduction of egress capacity can be made provided changes do not reduce the effectiveness of the means of egress in terms of its basic characteristics. Those basic characteristics would include number of exits, egress capacity, quality of exit enclosures, remoteness of exits, etc. Item 5 - Height and Area Limitations The architect has proposed to identify the 1940 building (and a proposed addition to that building) as Building 2 while the 1966 addition is identified as Building 3. The existing buildings have the following characteristics: Peter Frothingham, PFA Page 4 September 4, 1998 The terms "substantially altered" and "substantially renovated" are defined in the MSBC as follows: "work which is major in scope and expenditure when compared to the work and expenditure required for the installation of a fire protection system. . . . " (MSBC 3401 . 1) As these terms have only been introduced in the Sixth Edition of the MSBC, there is little or no clarification of the terms available at this time in the interpretative actions of the MA Board of Building Regulations and Standards through its appeal decisions or interpretations. Given the scope of demolition, renovations and additions which are planned in this project, it is likely the project would be considered to be a substantial alteration. In that case, the building would be required to be provided with any and all of the fire protection systems required by MSBC Chapter 9, Fire Protection Systems for a new building. Code requirements concerning other building characteristics such as means of egress conditions, vertical openings (open stairs) and exterior wall ratings will be affected by the provision of automatic sprinklers in the building. (8 ) Open stairways are not permitted unless they satisfy the MSBC criteria for an unenclosed vertical opening. (3404 . 13) There are no building code provision which allow an open stair to serve as a required exit except from a mezzanine. It does not appear that there are any open stairs or other floor openings in the existing building which would be affected by this provision. Stairs not required for egress capacity could remain unenclosed if arranged as required by the code for new construction for an unenclosed stair. The best basis for a two story unenclosed stair is found in MSBC Section 713.3, Exception 2. MSBC Section 3407.0 will require that any modifications of the building' s exterior envelope including replacement of windows be done in accordance with the requirements of Section 3407. 0. That section may also require improvement of existing mechanical (heating and air conditioning) , electrical and lighting systems which are being modified. Peter Frothingham, PFA Page 3 September 4, 1998 fullest extent practical. However, individual com- ponents of an existing building system may be repaired without requiring that system to fully comply with the code for new construction unless specifically required by MSBC 3408. Section 3404 .4 states the following: Alterations or repairs to existing buildings which maintain or improve the performance of the building may be made with the same or like materials unless required otherwise by MSBC 3408. The two code provisions cited above (MSBC 3404 .3 and 3404.4 ) will control work done to upgrade the electrical, heating and plumbing systems and make cosmetic improvements. Other subsections of MSBC Section 3404 . 0 require the following: ( 1) Every floor or story shall be provided with at least the number of means of egress required by the code for new construction which are acceptable to the code official. (3404 .5) (2 ) The means of egress shall have capacity as required by MSBC Section 1009.0 for new construction. (3404 .6) (3) Exit signs and lighting shall be provided as required by MSBC Section 1023.0 for new construction. (3404.7) (4 ) Means of egress lighting shall be provided as required by MSBC Section 1024 . 0 for new construction. (3404.8) (5) The building shall not be increased in height or area unless the combined height and area of the building and any additions comply with the height and area limitations of MSBC Chapter 5. (3404 . 9) ( 6) Existing fire walls are not required to be upgraded to compliance with MSBC Section 707. 0 . (3404 . 10) ( 7 ) Fire protection systems are required as specified by the code for new construction in additions, in the existing building and any additions when required to satisfy height and area limitations and in any building or portion thereof which is substantially altered or substantially renovated when such systems are required by MSBC Chapter 9.00 in new construction. (3404 .11, 12) Peter Frothingham, PFA Page 2 September 4, 1998 That summary of code requirements indicates the architect considers the existing complex to consist of two separate buildings which are referred to as Buildings 2 and 3. A portion of the proposed new construction is considered to be Building 1 . A second part of the new construction will be an addition to Building 2 . The building is presently occupied as a mixed use building having Assembly (Use Groups A-1, A-3 ) and Educational (Use Group E) spaces. In addition, it also contains Use Group B, Business (administrative and faculty offices) which, depending upon its area, may be a primary occupancy or an incidental occupancy of the building. Those uses will not change. For purposes of analysis of the requirements of MSBC Article 34, therefore, there will be no change of use and no change of the hazard index. Proposed Work An addition to the complex which will include a new gymnasium, cafeteria and band room will be constructed to the west of the present complex. A fire wall is indicated to be provided between the gymnasium/cafeteria portion of the addition and the band room portion. As a result, the gymnasium/cafeteria portion has been treated as a separate building (Building 1) for building code purposes. The band room and adjacent spaces will be treated as an addition to existing Building 2 . The proposed work will also involve modification of many areas of the existing building and upgrading of a large part of the mechanical and electrical systems. It will also include installation of automatic sprinklers throughout the existing building. Of course, the new construction is subject to the full requirements of the MSBC for new construction. Code Requirements for Existing Buildings Chapter 34 of the MSBC contains that code' s requirements for repair, alteration and addition to existing building. In this situation, in which there is no change of use or hazard index proposed, any repairs and alterations would be controlled by MSBC Section 3404 .0. Section 3404 .3 requires the following: Any new building system or portion thereof shall conform to the MSBC for new construction to the i Harold R. Cutler, P.E.

It is submitted to put into perspective the code requirements for upgrading that building to compliance with current building code requirements and adding to that building. It will also discuss the degree of compliance of the plans for the project with those requirements and identify some modifications of those plans discussed with the project architect, Kaestle Boos Associates. This letter is based upon my review of the "Coordination Plans" dated March 30, 1998 prepared by Kaestle Boos Associates, Inc. , our discussions of those plans prior to September 10 and our meeting on September 10 with Northampton Zoning Enforcement Officer Anthony Patillo and Mike McKeon of Kaestle Boos Associates. Existing Conditions The original (1940) building is indicated in the Code Summary provided on Drawing R1 .00 to be of Type 2A, protected noncombustible, construction. The 1966 addition is of Type 2C, unprotected noncombustible, construction.

Additions to Northampton High School + Athletic Field Improvements; Northampton, MA 40 40 40 Appendix 1 Test Boring Data + Location Plan 8.0 REPORT CONDITIONS: This report has been prepared for specific application to the subject project in accordance with generally accepted soil and foundation engineering practices. No other warranty, express or implied, is made. In the event that any changes in the nature, design and location of structures are planned, the conclusions and recommendations contained in this report should not be considered valid unless the changes are reviewed and conclusions of this report modified or verified in writing. The analyses and recommendations submitted in this report are based in part upon data obtained from referenced explorations. The extent of variations between explorations may not become evident until construction. If variations then appear evident, it will be necessary to re-evaluate the recommendations of this report. Clarence Welti, P.E., P.C., should perform a general review of the final design and specifications in order that geotechnical design recommendations may be properly interpreted and implemented as they were intended. Subsurface explorations for the subject study have been performed by Clarence Welti Associates Inc. solely for geotechnical purposes. Environmental impact studies have been performed previously by others. The subject study shall not be construed to be an assessment of environmental impacts, now or in the future. 17 7.0 Regarding the proposed Retention Basin on the south end of the site borings D13-1 thru DB-5 were drilled to a depth of about 10 feet or to about Elev.143. The proposed basin bottom will be at about Elev. 147. The present water table is at about Elev. 150. The basin will have a new outlet culvert across Federal Street at Elev. 147. The bottom of the basin will be generally in the Sand and Gravel, but the Clay layer is at Elev. 144 to 146. The Clay will tend to control the water table. The water table will remain close to the bottom of the basin because of proximity of the Clay. Design of vegetation for the basin must address this condition, if it is to be vegetated. It is suggested, that the basin be sloped toward the channel in the middle to permit underdrainage of bottom, which could maintain the water table below the surface over much of the bottom. The under drains would be placed in a bed of 3/8" stone about 18" below the bottom at about Elev. 147 to permit flow from the basin. 7.1 It is recommended, that the slopes be 3 to 1 or flatter. The portion of the slope below Elev. 150 should include at least 24" of 1/2" stone to permit weeping without sloughing. 7.2 It is noted, that gas pipeline traverses the basin and will probably obtrude into the area. 16 track will have rubberized bituminous concrete under the patented surface treatment. If the track is a cinder or clay track, the processed stone and bituminous concrete would not be included. 6.6 The football field will have seasonal water tables within 3 to 4 feet of grade. Underdrainage will be required, if irrigation is proposed. The soils in the top 3 feet will have some Silt and there should be a minimum of 18" of sand or sand and gravel below the topsoil to direct storm water recharge or irrigation water to the under drains. The drains should be placed about 3.5 feet below the field on 25 feet centers. 6.7 Other athletic facilities, including Baseball, Softball , Soccer and practice fields were investigated with borings P-11, P-13, P-17, P-20, P-22 and P-27. The soils cross section consists generally of 6 to 8" of topsoil overlying Fine Sand and Silt to 2 to feet above compact Coarse to Fine Sand and Gravel with little Silt. The water table was at about 3 to 4 feet over most of the fields.There is a gas line through the field and the water table is locally deeper in this area. 6.71 The fields are presumed to have irrigation. The upper soils have moderate permeabilties, but there would be ground water mounding without an underdrawn system. The drain system should be similar to that at the football field,namely at about 25 feet on centers and about 3 feet below the football field. The field should have a minimum of 12" of sand beneath the topsoil and turf to permit seepage to occur rapidly toward the under drains. 15 be close to grade at the west side. It is possible, that the subgrade will be somewhat soft over parts of the subgrade in wet seasons, due to frost/thaw cycling in the silts. The pavement section should include an initial 18" layer of gravel subbase after the topsoil is stripped and the subsoil is proof rolled with a 5 Ton roller. There shall be initial vibratory rolling, which would be halted, if there was Ak weaving of the soils. The 18" of gravel (DPW"Gravel Borrow") shall be placed in one lift, prior to compacting. Atop the gravel there shall be a 5" layer of"Dense Graded Crushed Stone Subbase". The surface shall include a total of 3" of Bituminous Concrete (two layers of 1.5", top course over binder). 6.3 The parking lot near the bleachers will require stripping up to 12" of topsoil and possibly 1 to 2 feet of organic Silt. Based on the presence of organic Silt, it maybe necessary to place and initial 15" layer of 3/4" stone on a geotextile beneath the cross section at the main north parking lot. 6.4 The bleacher area has an irregular soils cross section. consisting of as much as 18" of topsoil with localized areas of organic Silt or simply topsoil over sand and gravel. It is presumed, that the bleachers will be supported by piers. The piers should be carried to at least 4 feet below grade with localized areas requiring placement at 5 to 5.5 feet. The allowable loading at the bottom of the piers on sand and gravel can be 5,000 psf. 6.5 The track area appears to have relatively compact soils beneath the topsoil, some of which is previously placed fill. The topsoil must be stripped and a minimum depth of"Gravel Borrow" of 18" shall be placed beneath a 6" layer of compacted "Processed Stone Subbase". It is assumed, that the w 14 6.0 SITEWORK AT BALLFIELDS AND PARKING AREAS: 6.1 The Access Road to the rear of the building will traverse about 10 to 15 feet below north west building corner and 10 to 20 feet above the contiguous ballfield (track area). Boring SB-6 does not indicate a Silt Clay layer in the fill area near the ballfield and a retention system can be placed in this area without serious effects on slope stability. The retention system could be Reinforced Earth`' or varieties of this system, precast walls or cast in place walls. The parameters for the wall or retention system shall be as follows: Coefficient Value Soil unit Weight 125 pcf Angle of Internal Friction 4 340 Passive Coefficient 5.0 Friction Concrete to Soil S 17.50 Bearing at Frost Depth 4,000 psf 6.11 The access road will be constructed within the parameters, cited in section 4. Topsoil must be stripped, where present. The existing parking areas could be recycled to provide a future base course for pavement of the roadway or the new parking areas. 6.2 The new parking area to the northwest (see Borings SB-9 and SB-10) will be atop an area with 4" to 12" of topsoil atop a Fine Sand with little Silt. There are layers of soil below 4 feet, which have organic contents (apparently old river deposits). The water table is within 4 feet of grade. It is presumed(based on access requirements), that the parking area will be filled on the east side and will 13 5.5 SLAB ON GRADE TREATMENT: The parts of the proposed new structure, which will be less than 5 feet above existing grades can be slabs on grade and will perform within the above criteria, as concerns settlements. The areas, which have higher fills and fall above existing (potentially consolidation prone) will require STRUCTURAL SLABS to perform within the above settlement criteria. The slab could be supported by caissons or on piles, since the high fill area is distant from the existing building and would not be affected by pile driving. The use of piles or caissons would be dictated by the loading and the normal column spacing in the structural slab area. In general fill and backfill under the slab on grade have been described in section 4.2 (above). This material must be compacted to at least 95% of modified optimum density(ASTM 1557D). The underlayment for the slab shall include a vapor barrier with a layer of 3/8" stone atop the vapor barrier. This configuration will provide the requirements for proper slab curing; placement with small machines and it will provide assurance of capillary water cutoff. The stone should be about 5" thick to permit machine spreading and compaction. Compaction of the stone with 2 to 3 passes of vibratory compactor with a compactor of 5 Tons static weight. 5.6 In areas with structural slabs the plumbing utilities (drains) must be supported by the slab. Considering this requirement, it would be advisable to minimize the amount of drains in the supported slab areas. 12 consolidation of the Silt Clays and the loose fills (if left in place). While a controlled fill could be placed (replacing the existing fills, which would support spread footings), depth of fill over the existing topography would leave serious questions, as regards the potential for future structure settlements. Furthermore there would be substantial costs in removing and disposing of the existing fill and replacing this material with a compacted sand and gravel. Based on these considerations, it is proposed to have the new building foundation extend to rock. This will exclude differential movements between the existing building and the new structure, as well as excluding differential *A movements within the new structure. The recommended foundation is drilled caissons, although H piles could probably substitute for the caissons. The caissons would exclude disturbance of foundations and slabs beneath the existing building. Typically the caissons would be carried 2 feet into bedrock or as far as caisson augers(not rock drills) would penetrate the rock. With a 3 feet diameter caisson the allowable caisson loading would be 290 kips(7sf x 30 ksf+ 2 x 10 x 4 ksf[side friction]). Actually there would be friction above the rock in the compact soils, but this has been ignored. 5.3 FROST DEPTH: The code frost protection depth is 48" below finish grades. Typically, if construction is in the winter, all footings would have to have frost protection. 5.4 LATERAL LOADING: The lateral soil pressure on retaining walls shall be at rest pressure, equivalent to a fluid of 60 pcf. Lateral loading from seismic forces(for a cantilever retaining wall)shall be an inverted triangular pressure configuration based on 5.5 HZ psf per foot. The reaction will be at 2/3H. For walls, supported top and bottom the loading shall be a uniform 11 H psf. 11 5.0 BUILDING FOUNDATIONS & SLABS ON GRADE: s 5.1 Criteria for assessing building foundations types and loading and the slab on grade requirements are as follows: 1. The allowable maximum settlement for the Structural system is V2" and the allowable differential settlement shall not not exceed '/2 the maximum settlement. 2. The foundation must address liquefaction, that might occur below water table during earthquakes. 3. Regarding Slabs on Grade the maximum total settlement shall not exceed '/z" and the differential shall not exceed '/Z that amount. 5.1 Regarding item 2 (SEISMIC CONSIDERATIONS) the soils below the water table, which have sample blow counts below threshold values (below which liquefaction is possible in loose Fine to Medium Sand) are in the Silt Clays, which would not be sub' t to coil liquefae,�he "S" factor for seismic design, based on BOCA, is 1.5. ''- ts '00,4 �� �' (' / ' 5.2 Regarding Foundation Types and Loading the potential for differential settlement has been discussed in section 2 and in section 5. The proposed structure will have localized significant column loading with high walls, which would be sensitive to differential settlements both from the 10 Compactor Weight/Dynamic force Layer Thickness 15 Ton 30 Ton Force 16" 10 Ton 20 Ton Force 12" 5 Ton 10 Ton Force 10" 1 Ton 2 Ton Force 6" 0.5 Ton 1 Ton Force 5" < 500 pounds <4" 9 MA the slab shall be 30". This will provide a base for equipment in the area, which will be required for placement of proposed foundations. The fill shall conform to the following gradation: Percent Passing Sieve Size 100 5" 50 - 100 3/4" 25 - 75 No. 4 ` The fraction, passing the No.4 sieve, shall have less than 10%, passing the No.200 sieve. This material must be compacted in layers, not exceeding 12" in thickness, to at least 95% of modified optimum density (ASTM 1557). 4.3 The earthwork in the site improvements (Ballfields & Parking Areas) is discussed in section 6. This will include the access road in proximity to the northwest corner of the proposed building addition. 4.4 The compaction requirement for embankments are as follows: Under Pavements within 5 feet of grade 95+% of modified optimum density Under Pavements 5 or more feet below grade 92+% of modified optimum density Under Ballfields 93+% of modified optimum density Under landscaping 90+% of modified optimum density 4.41 Compaction shall be in layers generally within the following parameters: 8 4.0 EARTHWORK + MELDING PAD PREPARATION: 4.1 As stated in section 1 the building floor will require about 8 feet of fill over the north 30% of the proposed addition and as much as 20 feet of fill at the northwest corner. The thickness of the Silt Clay varies from abou 25 feet the upper parking terrace t 10 to 15 feet the lower the terrace. There will be generally be less than 400 psf loading from soil loading at the upper terrace, which would result in Silt Clay consolidation of about V. The area to the north will have fill loading of 1000 to 1200 psf atop a prior fill loading of about 1000 psf. This superimposed loading will cause consolidation of the Silt Clay of about 3+ ". In addition to this value there will some consolidation of the loose existing fill. 4.11 The rate of consolidation would probably achieve 60%of the Silt Clay consolidation in less than 4 months. The placement of foundations would require removal of the existing fill to the Silt Clay, which would be in proximity to the wet Silt Clay. The placement of fill atop the Silt Clay would require treatment with a layer of stone on a geotextile. This process would probably cause some disturbance of the Silt Clay with subsequent future subsidence. 4.2 The amount of potential subsidence, particularly differential subsidence, is discussed in section 5 (Building Foundations). The potential settlement does lead to a decision to avoid a general removal of the existing fills and special preparation for spread footings. The earthwork will include recycling of the existing pavement for future use in the new parking areas. The area in the upper terrace will require new fill to the underside of the slab on grade. The minimum new gravel fill under 7 3.0 GROUND WATER+ MITIGATION: 3.1 The water table is generally controlled by the varved Silt and Clay. While the upper portion of this material will be desiccated during portions of year, particularly under areas, where the storm water recharge is limited. The water table is generally below the proposed floors, but footings may be in proximity to the water table or within the capillary zones atop the water table. 3.2 Where the floors or other elements are in proximity to the water table or are within the capillary zone, there may be a requirement of an initial 12" stabilizing layer of stone on a geotextile. "'t 3.3 The Ballfields will be seasonally in proximity to the water table and will be close to or at the capillary zone during most of the year. The treatment of surface and development of the fields is discussed in section 6 of this study. 3.4 There will be ground water at the large retention basin excavation, as well as seepage from the slopes at the basin. This condition is discussed in section 7 of the report • 6 Medium compact to compact Fine to Coarse Sand & Silt, little Gravel to the top of rock at about Elev. 140 Soft to medium hard Triassic Sandstone The water table varies from about Elev. 182 in the upper areas to about Elev. 166 in the lower areas. 2.3 SOIL PROPERTIES: 2.31 The Silt Clay has water content in a range of 35 to 45%, which would indicate a predominant Silt fraction or significant over consolidation of the stratum. The consolidation test indicates primarily the former condition. The value of the consolidation coefficient C,, is about 0. 15 . This value would indicate potential consolidation of up to 3" with superimposed loading (from fill) of 1000 psf and a thickness of 15 feet. The FILL is a mix of Silt and fine Sand with traces of Bricks and Roots. This material is generally loose and possible settlement of this material, where 10 feet thick could exceed 1". The material below the Silt Clay is a compact Fine Sand and Silt with little Gravel. It has a probable angle of internal friction � of about 35' and saturated unit weight of about 130 pcf. The bedrock, soft to medium hard Sandstone, can be drilled 1 to 3 feet with augers and will support 15 Tons/sf with side friction values of 1.5 to 2 Tons/sf. 5 2.0 SOILS CROSS SECTIONS AND SOIL PROPERTIES: 2.1 Boring Data, which are applicable to the Structure are the "B" borings. Several sections are included in appendix 3, which depict the presence of the Silt Clay. 2.2 An Overview of the Data indicates FILLs over much of the building footprint to as low as Elev. 167. The character of the FILL varies somewhat, but is appears to have come from the higher part of the original site and has significant amounts of building debris (probably from the original construction. The fill is generally loose and in lower areas (where the fill extends below Elev. 170) there are traces of organics and possibly clusters of organics, which were not removed when the area was constructed. The cross sections do depict the configuration but an overview would be as follows: At the Upper Parking Terrace (Borings 6, 9, 13, 21 and 22) From existing grade at parking area to Elev. 183/180 FILL; Pavement Underlayment + Loose Fine Sand & Silt Fine Sand and Silt or Silt and Fine Sand to Elev. 180/175 Silt and Clay or Silt with traces of Fine Sand Elev. 160+/- Medium compact to compact Fine to Coarse Sand & Silt, little Gravel to the top of Rock at about Elev. 150 Soft to medium hard Triassic Sandstone At Lower Parking Terrace (Borings 1, 7, 12, 15 and 16) From Existing grade to about Elev. 172/168; FILL; mix of Silt and Fine Sand with traces of Bricks and Roots (possible organic clusters) Varved Silt and Clay to about Elev. 160 4 consists of stratified Sands or Silty Sands on the upper terraces to varved Silt and Clay in the lower terraces. The deepest part of the glacial "valley" (top of rock) appears to be at about Elev. 130 to Elev. 140. At the building the bedrock is at Elev. 140 to 150. 1.3 Field Exploration has included 11 borings in the building areas, all of which were drilled to bedrock. The original boring program did not require drilling borings to rock and included 22 borings. When the clay was encountered, the borings were drilled to rock because of a possible requirement to place the structure on "extended foundations". In addition 27 borings were drilled in the areas of proposed sitework to a maximum depth of 34 feet. The depth criteria related to possible clay influence at large grade differences (i.e slide potential). 1.4 Laboratory Testing has included one consolidation test of the Silt Clay; water contents on Silt Clay samples to correlate with the consolidation test; 7 water content of the Silt and Clay and 7 grain size gradations in the soils underlying the varved Silt and Clay. In addition 2 grain size analyses in the ballfields and in earthwork areas. 46 3 story structure with a footprint of about 12,000 sf. The lower level will include a kitchen and cafeteria. The upper level will be a gymnasium. There is an unexcavated area to the east the gymnasium. A second upper level addition is proposed at the northeast corner of the existing building t with a footprint of about 2500 sf. The lower level is preliminarily assumed to be at about Elev. 188/187. This elevation will place the floor just above the upper parking terrace and will place foundations in proximity to the Silt Clay layer near the existing building. The upper level will presumably be at Elev. 200 to 203. This will require filling over the existing parking areas. The northwest corner of the main addition will be atop topography as low as Elev. 170. 1.21 Site Grading in Proximity to the Building will include a provision for an access road to the rear of the building (to replace existing access). This access must ramp up to Elev. 185 from the a lower level at Elev.165+/-. The access will be within 20 feet of the northwest corner of the building and a retention system appears to be required. The access will also be 10 to 20 feet above the contiguous ballfield area. A retention system will probably be required in this area. 1.22 Sitework apart of Areas near Buildings will include construction of a new parking area near Elm Street within the existing ballfields, construction of a new track and football field (with bleachers) and nearby parking areas, as well a new baseball and softball fields and soccer fields. The fields will presumably be irrigated. A large storm water retention basin is also proposed at the south end of the site. 1.3 Geologic Background: The major soil deposition at the site is of glacial lacustrine origin and 2 1.0 INTRODUCTION: The existing Northampton High School is a two to three story building of which the initial elements were constructed in 1920's or 1930's. The site topography, preceding the initial construction appears have been largely on a terrace at about Elev. 200 with a lower terrace at ,, the westerly part of the building at about Elev. 185. The upper glacial lake terrace soils were largely sands with little gravel and silt. The lower terrace appears to impinge on a varved Silt and Clay stratum, which is typical for lower terraces in the valley. The building configuration appears to have Ar advantageously used the topography in placing lower levels to avoid excessive filling in proximity to the Silt Clay stratum. It is understood, that some of the construction did encounter the wet Silts and there were special efforts, directed to addressing this condition. The topography to the west of the building (and particularly to the southwest) was altered in the initial construction or in subsequent phases. The lower areas of the terraces were filled to provide parking and access to the rear of the building. Much of the fill was not placed in a controlled manner for future building support and some of the original organics were not removed, prior to fill placement. 1.1 Existing Topography: The present topography drops from the lower floor (at about Elev. 192) to a parking area at about Elev. 186, which extend from about 25 feet from the north side of the building to about 80 feet from the building. This lot slopes to a second (filled) terrace at about Elev. 178. This terrace extends as an access to the rear of the existing building. The second terrace and the above access road to the ballfields is at about Elev. 160. 1.2 Proposed Building + Site Construction: The proposed building addition will include a two 1 Table of Contents Page(s) Introduction, include project description, geology, topography geotechnical issues, field exploration + lab testing 1 to 3 Soil Cross Section + Soil Properties 4, 5 Ground Water+Mitigation 6 Earthwork+Building Pad Preparation 7 to 9 Building Foundation+ Slab on Grade 10 to 12 Sitework: Ballfields + Access Roads, Parking Areas 13 to 15 Retention Basin 16 Report Conditions 17 Appendix 1; Test Boring Data+Location Plan Appendix 2; Laboratory Test Results Appendix 3 ; Soils Cross Sections Executive Summary The subject structure addition to the existing Northampton High School has a topographic setting with about 20 feet of elevation relief. From a geologic standpoint the site overlies a compressible Silt Clay stratum, as thick as 25 feet. The area within the building footprint has been partially filled with a much as 10 feet with a mix of soil, building materials (from prior construction) and organics. The proposed addition will abut the existing school with foundations in close proximity to the existing school foundations. The structure will support a gymnasium over a cafeteria with kitchen. Analysis of the structure with spread footings, either on the natural soil or on a compacted gravel fill (after removal of existing deleterious materials), would result in probable differential settlements up to 3". The settlements with spread footing design could be mitigated somewhat by placing a surcharge to achieve settlements prior to building construction. This initial effort would require removal of the existing deleterious materials and placement of controlled compacted fill, prior to placing the surcharge. Timing of removal would be somewhat open ended, but would probably require 4 to 5 months of waiting before building. There are obvious disadvantages to this scheme,which would require the initial investment, prior to starting the school proper. There may also be problems with the State funding for the preliminary work. Based on the above, it has been recommended to place the frame foundations for the structure on bedrock. The alternatives for placement of the foundations on rock are (1) steel H piles or (2) drilled caissons. These two alternatives will cause minimal silt clay disturbance under the existing building. The H pile might cause excessive vibrations. The caissons appear to provide the overall best acceptable solution at the subject site and are the recommended foundation. This solution will permit placement of column footings close to the existing building with relatively high loadings. Apart from the structural frame foundation, the slab in areas, where the superimposed fill exceeds 5 feet, will require a structural slab supported either in piles or caissons. The area of high fills already has up to 10,feet of deleterious fill, which would normally be removed. With the structural support this fill could be left in place. The areas with shallow fills near the existing buidling have minimal amounts of existing fill and would have settlements under 3/4". This would permit slabs on grade for 50% of the building footprint. i e sure in iected Footings with CASED shafts INSTALLATION ION PROCS-OUPE f�, a 1 -... ice.'�• \ \ f Iii�1`i%.�•i-1•i�`: t��i. ii.( ;/�%' �r�\�� j. �(� '!t��� ��/�� �</.i 1 etsr�pare r ,p,is D t eD r` ' I:d'Id.',:id'I. d,3 rl•re a�i,l rd�r!
