SELECTIVE COLLECTIVE AUTOMATIC PUSH-BUTTON OPERATION
Control of the elevator shall be automatic in operation by means of push buttons in the car numbered to
correspond to floors served, for registering car stops by"up-down"push buttons at each intermediate landing&
"call" push buttons at terminal landings. The momentary pressing of one or more buttons shall dispatch the
car to the designated landings in the order in which the landings are reached by the car, irrespective of the
sequence in which the buttons are pressed.
Each landing call shall be cancelled when answered. When the car is traveling in the up direction, it shall stop
at all floors for which car buttons or "up" hall buttons have been pressed; it shall not stop at floors when
"down" buttons only have been pressed, unless the stop for that floor has been registered by a car button, or
unless the down call is at the highest floor for which any buttons have been pressed. Likewise, the pressing of
an "up" button when the car is traveling in the down direction shall not intercept the travel unless the stop for
that floor has been registered by a car button, or unless the up call is the lowest for which any button has
been pressed.
When the car has responded to its highest or lowest stop & stops are registered for the opposite direction, its
direction of travel shall reverse automatically & it shall then answer the calls registered for that direction.
Should both up & down calls be registered at an intermediate floor, only the call corresponding to the direction
in which the car is traveling shall be cancelled upon the stopping of the car at the landing.
An adjustable time delay shall be provided so that after the car has stopped in response to a hall button, the
entering passenger may register his car button before the car will reverse to answer calls in the opposite
direction.
ELECTRONIC PASSENGER SENSING DEVICE

elevator car. In addition, an electro-mechanical reversal edge shall be provided on the leading edge of the car
door.

The doors will remain open as long as the electronic detector senses the presence of a passenger or object in
the door opening. If door movement is obstructed for a predetermined time, the doors will resume normal
closing operation. If the electro-mechanical reversal edge contacts a person or object while closing, the doors
will immediately stop & reopen. Closing will be initiated 1/2 second after the passenger or object has moved
from the opening.
�r
DOOR STANDING TIME SAVER
The doors shall remain open for an adjustable time for a stop in response to a car call & a second variable time
for a stop in response to hall call. If either beam of the electronic detector is interrupted & reestablished, door
open time for a car stop & for a hall stop shall be reduced.

EXCAVATE AND BACKFILL FOR:
40 All new elevator, adjacent entryways and related construction.
Exterior grading for mulched beds, new paving, new equipment pads and repaired paving.
40 Exterior lighting at front of building. See Electrical drawings for plan.
General: It is assumed that excavation and cutting of paving, etc., can be done by mechanical and/or manual
'00 means. Report immediately to Architect any extraordinary conditions which may be encountered in excavation.
Unauthorized excavation: Do not disturb existing or new foundation bearing surfaces. Do not overexcavate.
w Unauthorized excavation consists of removal of material beyond indicated subgrade elevations or dimensions
without specific directions of Architect.
Under footings: Fill (with concrete) unauthorized excavation by extending the indicated bottom
elevations to the excavation bottom without altering indicated top elevations.
Stability of sides: Slope sides of excavations deep to angle of repose of material excavated; otherwise shore
and brace where sloping is not possible. Take precautions to prevent slides or cave-ins when excavation
subjected to vibrations from vehicular traffic or any other source. Provide minimum requirements for shoring
and bracing to comply with ANSI A10.1 "Safety Code for Building Construction" and with local codes and
authorities having jurisdiction.
Dewatering. Perform earthwork in a manner to prevent surface water and ground water from flowing into
excavations and to prevent water from flooding the project site and surrounding area. Do not allow water to
accumulate in excavation. Remove water using dewatering methods which will prevent softening of foundation
bottoms, undercutting footings and changes detrimental to stability of subgrades and foundations. Provide and
maintain pumps, sumps, suction and discharge lines necessary to convey water away from excavation.
Material storage: Stockpile acceptable (for fill or backfill) excavated materials until required for reuse. Locate
and retain materials (coordinate location with Owner) away from edges of excavation to prevent materials from
falling or sliding into excavation.
w
Remove excess and unacceptable excavated material from site.
EXTERIOR BACKFILL-ROUGH GRADING
