Page 2 – Amendment A0001 to 36C24121Q0457 Project - Bldg 31 Transformer Cooling Fans Installation at VA White River Junction

The following Requests for Information with the responses are provided:

Q. Can you provide nameplates and drawings for each transformer?

A. Photos of the name plates are attached. There are two attachments and they are titled T18 Transformer and T17 Transformer.

Q. Can you provide nameplates and/or specifications for the existing parts that are being replaced so we can source equivalent? Or do you have specifications of alternate new equipment that you specifically want?

A. From the SOW: Six (6) 120VAC cooling fans

· Mounting brackets

· Two (2) digital transformer temperature monitors and controllers

· Two (2) control power transformers

· SIS wiring

· Six (6) insulated thermocouples

· Misc. items

Q. Can you provide oil quality and DGA oil diagnostics for each transformer?

A. Since the transformers are dry types, there is no oil used in the transformers.

Q. Can you provide photos of each transformer and/or map showing access around the transformer to perform the work?

A. Photos are attached. There are two attachments and they are titled Transformer Front Work Area and Transformer Rear Work Area.

Q. Is there any electrical testing required on the transformers? Or strictly functional checks of replaced parts?

A. The SOW does call for testing of the new cooling system at completion of the install.

Q. Please provide GE Fan model number for the Transformer Fans.

A. Currently no fan is in place.

Q. Are the 750KVA pad mounted transformers or dry types.

A. According to the SOW, the transformers are dry types.

Q. The “Statement of Work” 1.A: Indicates six (6) fans + the other equipment. Each Transformer will require Six (6) to Twelve (12) fans, or 12 to 24 Total Fans will be required for the 2 Transformers.

A. The main goal of the cooling fans is to increase the capacity of the transformers from 750 KVA to 1000 KVA. Past engineering investigations have pointed us towards 12 fans per transformer, for a total of 24 fans.
