Roybal Elevator Modernization Project 3

Federal Construction Group is tasked to examine the existing conditions, power supply, standby/emergency power supply, mainline disconnect, and include all work needed to ensure a fully code compliant modernization. Contractor or his sub-contractors shall perform this work, which may include but is not limited to the following:

Mechanical:
1. Hoistways: Construction and modifications of hoistways, waterproof pits, machine rooms and controller areas, all properly framed, enclosed and adequately ventilated as shown.

Electrical work:
1. Power feeders: Modification to existing or installation and connection of three phase power through fused mainline switches or circuit breakers and extended to terminals of controllers. Provide continuous ground where needed.
2. Light circuits: Single-phase circuit through disconnects and extended to controller for car lights and fan.
3. Communication circuit: Telephone circuit terminated at junction box of each controller.
4. Illumination: Lights, light switches and GFIC convenience outlets in pits, machine rooms, controller areas and overhead sheave spaces.
5. Conduit: Installation of electrical conduit and pull boxes with pull wire between hoistways and remote locations of each indicator and control panel.
6. Temporary power: Electric power during construction for installation.
7. Common circuit: Dedicated pollution free single phase 20-ampere circuit through fused mainline switch or circuit breaker and extended to common group controller for each bank of two elevators or more.
8. Standby power: Automatic transfer of standby/emergency power and lighting supply through normal feeders with means of absorbing regenerative power. Two No. 14 wires from “Form C” contacts on transfer switch to designated controller to elevator machine rooms to signal transfer of power.
9. Sensing devices: Installation and or modification to smoke detectors, heat detectors or products of combustion sensors in elevator lobbies, machine rooms, hoistways and alternate fire recall floor with circuits terminated at junction box in machine rooms for emergency fire service operation.
10. Life safety circuits: Circuits terminated at junction box at each controller for life safety speakers and fireman’s phone communication. Note phone jacks are not permitted in corridor call button boxes.

General:
1. Access: Legal access consisting of self-closing and locking access doors, ladders, gratings and steps to machine rooms, controller areas, pits and hoistways.
2. Supports: Providing supports as shown to carry structural reaction, impact and uplift loads imposed by elevator equipment.

3. Sill supports: Support full width of hoistway at edge of slab for attachment of sill support angles to be provided and installed by Contractor.

4. Grouting: Grouting behind entrance frames where concrete walls occur.

5. Patching: Patching of floors, walls and surfaces constituting final finishes.

6. Block-outs: Block-outs, pockets and chases in walls and floors for entrances, signals, fixtures, cables and conduit.
