14 20 00.  Elevators

14 20 50.  General Requirements for Elevators

Both machine room-less (MRL) and traditional traction elevators are acceptable for use in UW Madison campus buildings.

14 20 51.  Provisions for Penthouse Access

All mechanical penthouses shall be accessible by a hospital sized elevator, which can handle an emergency stretcher. This is usually, but does not have to be, a cab designated for freight which is provided with cab pads.

14 20 52.  Materials

  1. Wall panels within elevator cabs may be specified to meet the needs and preferences of building occupants and blend with the architecture of the building, however care shall be taken to select materials that are durable, resistant to cart damage, and can be easily cleaned.
  2. Flooring within elevator cabs may be specified to meet the needs and preferences of the building occupants however thought shall be given to slip resistance, durability, and cleanability. If elevators are near the building entrance, it is likely the floors of the cab will come in contact with water and salts.
  3. Materials to be used for padded protective wall pads or “cab pads” shall conform to ASME A17.1, Rule 204.2a (1) or (2). Cab pads shall be provided for a minimum of one elevator cab in each building. This shall be the elevator designated to go to the penthouse.
  4. The floors of all machine rooms and pits shall be either painted with a light color coating or sealed concrete.
14 20 53.  Monitoring System

In terms of monitoring, each elevator controller shall be connected to the building automation system (BAS) for fault reporting. The contractor shall install a 18/2 conductor from each controller to a BAS point that is programmed to see and report the fault contact closure. A fault point on the BAS shall report to both the UW Electric Shop and the building manager via email that the elevator is faulted and is non-operational. (This should be in the HVAC controls specification as well.)

14 21 00.  Electric Traction Elevators

  1. Elevator doors shall be a minimum of 40 inches wide and 6 feet-6inches high. The needs of the building occupants shall dictate the requirements for larger or taller opening sizes and/or increased cab heights. In addition, the General contractor shall provide a clear and plumb hoist-way. All freight elevators shall have steel C-channel jambs with steel angle sills. Jambs shall have solid metal extensions 4 feet above and 4 feet below door opening for door track mounting.
