Specification Section 14.21.00 – Traction Elevators

· Per section 1.1 / 1.13 (C) Elevator Schedule: the specification calls for an overhead gearless elevator. Pages A-701 and A-702 of the Drawings indicate a machine room-less (MRL) traction elevator, but also show a machine room above. Will the elevators specified for Buildings 8 and 9 be overhead traction or machine room-less traction with the controller above in the new room? The elevators shall be overhead gearless traction elevator systems.

· Drawing 1/2 S-3.01 Hoistway: Drawings show the hoistway ceiling/attic floor being raised to accommodate the MRL equipment. This height will change depending on the material manufacturer if the car is indeed an MRL. The elevators shall be overhead gearless traction elevator systems.

· Per section 1.1 (C) Elevator Schedule: The existing elevators have 2-speed side slide doors. The entrance type and size are listed as center opening two speed. Drawings A101-102 indicate two-speed side opening doors. We are requesting clarification on the door type. Existing elevators have nothing to do with new construction. Doors shall be side opening, two speed.

· Per section 2.42 (H) Hoistway Entrances: The specification calls for single-speed center opening doors which is in conflict with the elevator schedule and architectural plans. We are requesting clarification on the door type. Existing elevators have nothing to do with new construction. Doors shall be side opening, two speed.

· Per section 2.46 (N) Car Enclosure: Passenger: The specification calls for single-speed center opening doors which is in conflict with the elevator schedule and architectural plans. We are requesting clarification on the door type. Existing elevators have nothing to do with new construction. Doors shall be side opening, two speed.

Section 2.46 (K,1) calls for indirect LED lamps mount in lighting coves with no hanging ceiling. The existing elevators have standard frame ceilings with diffusers. Which ceiling type should we include? Existing elevators have nothing to do with new construction. Specifications have been edited to reflect requirements for Cabs 14 27 00.

· Per section 2.6 Controller and Supervisory Panel: If the cars are duplexed, should the group panel be in the new or existing room. The new elevators buildings 8 and 9 shall be simplex.

· Per section 2.7 Microprocessor Control System: During the site walk a question was asked regarding the new elevator systems for Building 8 and 9 working in group operation with the existing simplex elevator equipment. If group operation is desired, the existing simplex elevators may require software upgrades to the existing controllers to enable group operation or the existing ones may need to be replaced. We are requesting clarification. The new elevators buildings 8 and 9 shall be simplex.

Specification Section 14.24.00 – Building 10 Hydraulic Elevator Modernization

· Per section 2.15 Hydraulic Plunger Assembly and 2.16 Hydraulic Cylinder Casing and Well Hole: the existing hydraulic plunger assembly and cylinder casing were installed with the original project, approximately ten (10) years after the manufacturer produced the last of their single bottom bulkhead jacks. We request confirmation the existing jack assembly may be retained and this scope of work eliminated unless there is currently an indication of an underground hydraulic fluid leak. Specs have been edited to retain the existing jack assembly.

Specification Section 14.27.00 – Elevator Cab

· The design for cab interiors is included in the specifications for building 8 and 9. Does this section only apply to the elevator in Building 10? Section 14.27.00 applies to all elevator cabs for buildings 8, 9 and 10.
