D. GSA Work Item No. [S]:

II. BACKGROUND

There have been two completed phases of renovation for the building. The first phase of renovation was known as Phase 1A. Phase 1A consisted of 8 floors of renovation including systems, tenant fit-out and structural upgrades. Phase 1B was the initial phase renovation of the building. The building systems and standards developed for Phase 1B set the standard and serve as a precedent for the subsequent phases of renovation including Phase 1C (construction completion 2018) and Phase 2.

In particular, this project will address the renovation and modernization of the elevators located in the Phase 2 area of the building. Phase 2 and 2A renovations of the building are proposed.

III. CURRENT CONDITIONS

The modernization of the elevators during Phase 2 is critical to providing safe and reliable elevator service to the building occupants. These elevators are nearing the end of their useful life and most components will need to be replaced, refurbished or otherwise rehabilitated. The elevators were originally manufactured and installed approximately 50 years ago and partially modernized in 1991.

These elevators are in average condition for this vintage of equipment and type of motor control system.

However, changes in equipment design and technology have made many of the individual components obsolete. Planning should include replacement of the components to provide system reliability, increase performance, and to maximize the energy efficiency available with current technology.

The existing passenger elevator cabs and elevator lobby signaling systems are in average to poor condition and are not properly located for accessibility by the disabled. The systems will need to be replaced to meet ADA accessibility guidelines and code requirements. Retained equipment not replaced will be reconditioned.

The modernization of the elevators will also include upgrades and renovations to the elevator power systems located in the Elevator Machine Rooms. The Elevator Machine Rooms and the Elevator Pits will need to be surveyed for code conformance in accessibility, lighting, mechanical, and fire protection systems.

IV. PROJECT SCOPE

The elevators identified in Table 1 are in need of major renovations. See Appendix A for the Elevator Location Diagrams. The Design/Build Contractor shall prepare designs for and upon approval complete contract documents for the rehabilitation of said elevators which shall include the following items (see Table 1):

Any elevators that are on normal building service will still respond to the regular hall call buttons.

d) There is a digital lantern/gong fixture above each elevator on the first floor. When an elevator arrives and is on normal automatic service the fixture signals either read, ‘THIS CAR UP” OR “DOWN”. When the elevator arrives and is on “EXPRESS to 8” service the fixture signals

“DIPLOMATIC RMS”.

e) When any of the elevators are turned on to “EXPRESS TO 8” service, both regular 8 th floor down hall call buttons will disconnect from normal building service and only call elevators that are on “EXPRESS TO 8” service. There is a sign above each button that illuminates when any of the cars are on “EXPRESS to 8” service. The sign reads “EXPRESS TO LOBBY.”

f) There are two separate down hall call key-switches located on the 8 th floor that will set a normal hall call for any elevators that are on normal building service, when this key-switch is initiated there is a white jewel lengths that is illuminated until a car arrives to answer the hall call. This key switch will operate anytime there is at least one elevator on normal building service. The two 8 th floor down hall call key-switches will set a down hall call as long as one elevator is on normal building service.

g) “EXPRESS TO 8” External Mechanical time clock in MR is a 24 hour time switch with skip-a-day and reserve power. This clock will turn on “EXPRESS TO 8” for a single car and control the hall call services as outlined above. There is a rotary switch to choose which car will be selected for “EXPRESS TO 8” floor service.

h) Time clock has a toggle switch mounted in the housing. Note: Toggle switch controls the clock contacts, not the clock motor. Toggle switch in up position is “8 th floor service always on” for one elevator. (No matter what the time clock is doing.) Toggle switch in middle position is “no 8 th floor service” for the single car (No matter what the time clock is doing). Toggle switch in down position is “clock only” service. (8 th floor “EXPRESS TO *” service is controlled to one car.) The key switches in the 1 st floor lobby panel operate separate and independently from the MR time clock.

Mechanical time clock in MR is time to “ON” position.

Elevators service all floors including 8 th floor. 7 th floor up hall call will set up a hall call. 8 th floor hall calls will call all cars that are on automatic service. 8 th floor mechanical car call key switch in elevator will initiate 8 th floor car call on automatic, independent, attendant and “EXPRESS TO 8” service. 8 floor car call button will initial 8 floor car call on automatic, independent, attendant and “EXPRESS

TO 8” service. “AUTO TO 8” External Mechanical time clock in MR is a 24 hour time switch with skip-a-day and reserve power. Time clock has a toggle switch mounted in the housing. Toggle switch in up position is “8 th floor service always on.” (No matter what the time clock is doing) Toggle switch in middle position is “no 8 th floor service” (No matter what the time clock is doing). Toggle switch in down position is “clock only” service. (8 th floor service is controlled by the time clock only.)

Fire service overrides any of the 8 th floor special services. Note: Toggle switch controls the clock contacts not the clock motor.

Provide sequential step scan car calls. This allows compliance with the ICC/ANSI A117.1-2003 requirements to accommodate passengers who are short or are using a wheelchair in buildings where the car control buttons are more than 48 inches above the floor. Scan Up and Scan Down buttons are used. When “Scan Up” is pressed, the car call buttons above the current floor are scanned. When “Scan Down” is pressed, the car call buttons below the current floor are scanned.

When the button is released for more than 2 seconds, a call is registered for the last floor selected.

This option is enabled when the Sequential Step Scan inputs are programmed.
