Sec�on 14 21 10

THE GOAL OF THIS PROJECT IS TO BRING EXISTING ELEVATORS TO CURRENT

CODES AND REGULATIONS. PER SPECS, ALL CABLE, WIRE, ELECTRICAL (POWER

AND FIXED INSTALLED) WILL NEED TO MEET ALL CURRENT CODES AND

REGULATIONS. REFERENCE PARA. 2.3.

4. Will the pla�orm be replaced or refinished?

You generally would not replace the pla�orm and retain the cabin shell as the cabin shell would have to be removed to replace the pla�orm. 2.45 Is vague on if the pla�orm will be reused - Most everything else states the reuse of major components but 2.45 seems to allude to a new pla�orm and car entrance - 2.46 is contradictory sta�ng reuse cabin shell and refinish cabin entrance.

2.45 CAR PLATFORM: PASSENGER/SERVICE ELEVATORS

A. The pla�orm shall withstand the forces developed under the loading class specified. Provide car entrance with new stainless steel sill with machined or extruded door

2.46 CAR ENCLOSURE: PASSENGER/SERVICE ELEVATORS

A. Reuse exis�ng car enclosure. Refinish or replace damaged stainless-steel entrance panels.

B. Securely fasten car enclosure to pla�orm by through bolts located at intervals of not more than 457 mm (18 in.) running through an angle at the base of panels to underside of pla�orm.

KEEP EXISTING PLATFORM AND REFINISH AS REQUIRED.

5. Will the interiors be replaced?

2.46 CAR ENCLOSURE: PASSENGER/SERVICE ELEVATORS

A. Reuse exis�ng car enclosure. Refinish or replace damaged stainless-steel entrance panels.

B. Upon loss of normal power supply there shall be a delay before transferring to emergency power of 10 seconds minimum to 45 seconds maximum.

C. Prior to the return of normal power an adjustable �med circuit shall be ac�vated that will cause all cars to remain at a floor if already there or stop and remain at the next floor if in flight.

Actual transfer of power from emergency power to normal building power shall take place a�er all cars are stopped at a floor with their doors open.

D. Car ligh�ng circuits shall be connected to the emergency power panel.

YES ALL BUILDINGS WITH ELEVATORS HAVE EMERGENCY GENERATORS.
