Please note the only priming called for in section 080352 is related to new window should it be determined an original window cannot be repaired. Existing windows are already primed and painted.

However, there are other references that indicate 080352 will prime the sash and 090391 will apply field finish coats.

Will this trim be refinished in the field after the installation of the replacement windows? ANSWER: Refinishing will be in-place 19. ALTERNATE #1 WINDOWS: Under Alternate #1, Window Types B, C, D, E. G, & H will not replaced. The plans indicate that these windows and their associated brickmold will instead be cleaned, repaired, and painted. Please clarify the following: A. These windows aren't called out to be removed and repaired/rebuilt like the restored windows Al, A2, and F. Can you clarify how the process for repairing these windows differs from the process for repairing the Al. A2, and F windows?

Please clarify the following: A. The scope of work in the tower shown 011 Al .2, A3. 1. and A4. l does not include any finishing of the existing railings/or the stair tower. Ca11 you confirm that these existing railings don't need to be finished? ANSWER: See Specification Changes and Drawing Changes above. B. If the stair railings do need to be finished, which trade/specification section is responsible? ANSWER: See Specification Changes and Drawing Changes above. C. Section 090106.91 is responsible for staining, sealing, and applying polyurethane finish coats to existing wood flooring. Does General Note 1 near 2/A4. l refer to finishing the FLOOR of the balcony and stairs or to the structure itself?

Can you clarify finish requirements for floors, stair structure ( including treads/risers), and railings? ANSWER: See Specification Changes and Drawing Changes above. 21. 040322, 2.05, A calls for masonry restoration anchors. I don't see these on the plans -please clarify where these are being used.

ANSWER: Masonry work by Mason 23. 040323, 2.03, A&B call/or selallts (sic) and backer rod. Plese (sic) clarify where this will take place, as I don't see it on the drawings. ANSWER: Material may be used as conditions require. 24. Will the stone masonry require a cleaning prior to repainting, and upon completion of repainting? Or only after the repainting? ANSWER: Review specification sections: Masonry Cleaning generally best after cutting, but necessary before repointing. See Masonry specification sections -Final Cleaning required after work. 25. Who is responsible for the purchase and install of the new step flashing at the base of the tower where the stone is being removed and reset? ANSWER: Hashing is part of the FSB for Roofing and Flashing 26. Page D2. 1 at the bottom of the page says Masonry area 4,200 sqft, and Total Masonry Opening Area 560sqft. Would that mean that the total amount of repainting on the south face and portico would be 3,640? ANSWER: Correct 27. Please confirm the total masonry area includes the brownstone as well as the granite stone. ANSWER: Total masonry areas include brownstone and granite 28. Please confirm that the we should be using these sqft amounts at the bottom of each page of our quantities, as there is 110 reasonable way for the subs to field measure the building. ANSWER: Square foot amounts were provided for your use 29. On D2.3 011 the left side of the page there ia s note that is title Cutting and Ppointing. Under the base bid description is says to "Prep stone & Brownstone for cutting and pointing" Then below in the area titled Deduct Alternate No. 2 is says "deduct papenvork ... " My question is what is the tenn prep work referring to? In addition if the base bid is to prep, cut and point the masonry, but the deuct (sic) is to not prep should we assume we still have to repaint the area described in alternate to (sic). ANSWER: This question is unclear. Areas removed from the work by Alternate No. 2 will not be cut and pointed. 30. In the unit price form provided on page 3 of 4 in the Unit Prices spec OJ 22 00 the 7040 SF of repainting exterior stone masonry is the quantity for the total area included in the base bid, the 2250 SF quantity is the area that is to be deducted from that total area for alternate 2, so our unit price and total amount for that 2250 SF of stone repainting should be negative numbers, correct? ANSWER: See Specification Changes and Drawing Changes above. ADDENDUM 3 PROJECT #DCP 1828 HC I PAGE100F14
31. The contract documents call for files sub bidders to provide their own access. At the pre-bid it was mentioned that the GC's would be responsible for scaffolding and access.

ANSWER: General Contractor; See Sections 015000, Temporary Facilities, 3.03.E; and 017419, Construction Waste Management and Disposal 33. The contract documents have conflicting dates for project start. 240 calendar days is the project duration with a start date by September I and completion in February and also a goal of an October 19th contract award listed in the contract documents. Why is the state even proposing to do an envelope restoration of an historic structure with a 120" tower in the winter months? All of the masonry restorations specifications are very specific about no work under 40 degrees F and obtain in 28 day curing times on mortar prior to applications of sealers. ANSWER: See Specification Changes and Drawing Changes above. 34. How are the GC's going to project what temporary heating and protections costs are when the vary (sic) nature of the work has very stringent performance parameters which requires the work de done in the non-winter months. The potential for excessive costs for protecting the building and the real potential of having defective work due to winter conditions is a real concern regardless of attempting to protect the work in New England during the winter months. ANSWER: No winter conditions are anticipated for this project. 35. The 240 day construction calendar is only reasonable when coupled with starting this project in late winter when the heating of the envelope would not be required and the project during would end before the next heating season. ANSWER: See Specification Changes and Drawing Changes above. 36. Paragraph 1.06.B calls for professional structural engineering qualifications. Who is responsible for providing these qualifications and services? ANSWER: See Specification 085200 Paragraph 1.06.B.8 37. Specifications call for a whole unit u-factor of 0.24 and a SHGC of 0.27.
