Description

• Projects in this scope area may include: replacing or upgrading one or more elevator cabs; installing new machine motors, rails, hydraulics, and/or cables; repairing and/or replacing structure and walls in elevator pit and shaft; installing new sliding ADA (Americans with Disabilities Act) accessible car doors; installing car frames, enclosures, flooring, hoist ways, and lighting; installing mainline power switches, breakers, and feeders to controller, underground and/or buried piping, and emergency power plant, controls, and indicators; and installing Remote Elevator Monitoring System (REMS) and connection to BMS (Building Management System). The full, detailed scope of work for this project including any additional work areas will be updated here after alignment with project stakeholders through scoping and design activities.

Baseline

• Typical rehabilitation scope of work includes the following new components:
  • Permanent-magnet A.C. gearless traction hoist machines and motors
  • Cab enclosures including door operators and door zone locks.
  • Safety devices for unintended car movement and ascending car overspeed protection.
  • Controllers, selectors, Variable Voltage Variable Frequency Alternating Current (V.V.V.F. A.C.) motor drives, regeneration units, and remote elevator monitoring systems.
  • Car and hall signal fixtures—ADA-compliant car operating panel, hall button fixtures, digital position indicators in the car and at main floor, in-car traveling lanterns, emergency communication device, and phase I & II firefighter’s service.
  • LED lighting fixtures in the cab, pit, top and bottom of car, and LED bulbs/boards in the car and hall signal fixtures.
• Accessibility
  • All passenger elevators on an accessible route shall be accessible and comply with the ADA elevator accessibility requirements.
  • Where elevator doors are the manual swing type, convert them to the automatic side slide type.
  • When existing elevator shaft cannot be enlarged and is too narrow for ADA compliant cab and door size, accessibility requirements are guided by Voluntary Compliance Agreement (VCA).
• Hoistways
  • Elevator hoistways shall be pressurized as required by the NYC Building Code.
  • Elevator machine rooms opening into a pressurized elevator hoistway shall be pressurized upon activation of a heat or smoke detector located in the elevator machine room, control room or control space.
  • A pit with a sump pump shall be provided for every elevator, and a permanent lighting fixture shall be provided in the pit.
• Elevator Machine Rooms
  • Provide an approved means of access.
  • Per ASME A17.1, provide a minimum clear headroom of 84 inches for fire-rated enclosures and 79 inches for non-rated enclosures.
  • Provide an independent ventilation or air-conditioning system to protect against the overheating of the electrical equipment, The current standards require an intake louver and a thermostatically controlled exhaust fan with gravity damper sized for 45 air changes per hour.
• In buildings five or more stories elevator shall be provided with an elevator car of such size and arrangement that will be able accommodate an ambulance stretcher.
• In buildings with an occupied floor more than 120 feet above the lowest level of fire department vehicle access a minimum of one Fire Service Access Elevator shall be provided.
• Smoke detectors or other automatic fire detectors in environments not suitable for smoke detectors (fire alarm initiating devices) used to initiate Phase I Emergency Recall Operation shall be installed in conformance with the requirements of NFPA 72, and shall be located at each elevator lobby served by the elevator, in the hoistway when sprinklers are located in the hoistway, and the elevator machine room.
• A two-way emergency communication system should be provided in elevator cars. This system should establish direct communication with authorized personnel and must be activated by a push button.
• Elevators’ annual periodic inspections must be performed by an approved agency hired by owner, not DOB.
• PACT Partners should survey the existing conditions and submit a narrative evaluation summarizing the modernization scope for all elevators including components of the machine room, cab, hoist-way, pit, and overhead. Provide a detailed Scope of Work for all planned elevator modernization work assuming compliance with NYC mandated retrofits; include a summary of related trade work. The evaluation should include documentation of previous modernizations where possible, existing cab dimensions, and feasibility of cab modernization to meet minimum accessibility requirements. [PACT]
• Incorporate resident input into the design of interior cab colors. [COMPMOD]

Stretch

• Provide new, larger elevators with improved access for emergency medical services. [COMPMOD]
• Hydraulic Elevators (usually found in community centers)
