# Request for Information Response

Can the product specification for the breakers required in switchboard A&B (make & type) feeding panels WHP-2, IT-17-1 and IT-17-2 as shown on drawing 01-E39 be provided.

Please refer to specifications package for electrical specification requirements related to breaker requirements. Refer to drawings for breaker amperage sizes. Current breakers on SWBD AB are Westinghouse make.

121 The following light fixture types are not on the project schedule: B11, B12, B21 & B22.

Change the light fixture types in the Light Fixture Schedule as follows: Change N11 to B11; N12 to B12;

N21 to B21; and N22 to B22.

REF DWG. 01-E20: There are none of the following lighting control power pack symbols on any drawing. Please locate for takeoff

All the lighting control devices (relays) are located in lighting control panels. (Reference example below)

REF DWG 01-E35: Note 1 on drawing 01-E35 shows a feeder from existing ATS, in BOLD, with a note: "FOR CONT. SEE DWG 01-E22" Apparently this is not the correct reference.

1- Please indicate the correct drawing reference. (Is the correct reference 01-E36?) Plan reference for each of the indicated ATS's would be helpful as well.

2- Is there an actual new feeder from ATS 1 to the existing 400amp bus duct NODE 220 end tap box? Feeder Size?

Relocation of ATS, where?

3- Same questions for ATS 3 & ATS 7 4- Is transformer T7 (DWG Ref 01-E36) new or existing? Size? Location?

5- Are there 3 breakers in the MDP (450A, 400A & 600A) existing or new.

There is no intent to change any of the ATSs. The drawings are for reference only in regard to the ATSs.

The For Cont can be ignored as it was part of an existing VA set of drawings and showed normal feed to ATSs. Since there will be no work required this can be ignored.

REF DWG 01-E37: 1- Existing panels EECR9A & EELS9 are shown in BOLD being fed from 2 separate existing bus ducts from apparently new bus duct tap switches along with new feeders, is this correct?

1- Is the transformer fed from EECR9A relocated? Re-fed?

2- Is panel EECR9B relocated? Re-fed?

3- Please indicate bus duct manufacturer, model # and year of installation.

4- DWG 01-E36: Are the bus end tap boxes for NODEs 80 & 100 existing to be re-used and are the bus tap switches feeding panels SPP9, SPP9B, SLP (& ELP9 existing or new) 5- DWG 01-E35: Are the bus tap switches feeding panels SELS9, EECR9A, EELS9 & SECR9A existing or new?

The bus duct, bus duct tap switches, and panels EECR9A and EELS9 are all existing equipment. the transformer fed from EECR9A is NOT relocated. Panel EECR9B is NOT relocated.

The electrical design for lighting and power utilizes the existing panels for distribution. There is no work associated with existing panels except as provided by specific key notes. An additional panel will be required on the 9th floor in the west electrical room to accommodate new circuit needs. Two new panels are required for the IT room. An additional panel will also be required in the warehouse to accommodate new circuit needs. Two new panels will be needed in the new IT room in the warehouse. The Warehouse electrical design will involve relocation of an existing branch circuit panelboard and new distribution to the receptacles and HVAC units in the remodeled area.

REF DWG 01-E37: There are 2 panel SLP9s shown, one on DWG 01-E37 & one on DWG 01-E36. Is this an error? Please advise.

One sheet is the SLD & one is the Riser Diagram. This is not an error. Use either drawing to locate relevant panels to their floors. The drawings are reference drawings that were provided by the VA. For this panel the contractor can use the panel schedule shown as an existing panel to be reused.
