W9127P-16-R-0004 – Electricity to the MSAR

Q&A V.1

1. We don't have specifications for transformer type "PAD MOUNTED", that shall be installed:

Primary Voltage? Secondary Voltage? KVA?

a. A 3 phase 4 wire primary line will deliver 13.2KV to the transformer, the distribution panel board requires 1000 AMP MLU, 120/208, 3 phase, 4 wire Parallel 900 MCM. The transformer shall be designed to provide this to the distribution panel board. This can be found in drawing E-5.

2. Construction material; Stainless Steel or Galvanized Steel?

a. Stainless Steel

3. We don't see construction detail of the primary feeder line. Depth of the trenching?

a. The conduit to be used is already in place

4. Will the conduit shall be wrapped with concrete?

a. The conduit to be used is already in place

5. Wire size and Specs to be used?

a. 15kV 133% Coper One Conductor, conductor 2 AWG CU, Insulation Thickness 220 mils, Conductor Diameter 0.266 in, Insulation Diameter 0.74 in, Insulation Shield Diameter

0.80 in, Jacket Diameter 0.96 in, Cable Weight 590 (lbs/kft), Minimum Bending Radius 12 in

6. Exact location of the building on the map to be able to calculate the distance from the "PAD

MOUNTED TRANSFORMER” up to the building.

a. Building does not exist yet, provide access to the transformer so that connections can be made at a later date.

7. We read from SW 1-03 (Letter G) that the electrical works inside the building are not under the contractor, but that shall fully support of the electrical needs of the building. Please, explain.

a. There is no building in the current location at this point. We are prepping the area with electricity for its construction. The electrical load plans have been provided in which calculations can be determined.

8. Who will supply the distribution panels? Will them be supplied and installed by the contractor?

a. The distribution panels will be provided by the building contractor.

9. Please, elaborate about the distribution inside the building and up to what point the contractor shall reach for this project?

a. The building does not exist yet. The work is to take the primary line coming into the facility and installing a transformer that will satisfy the electrical power needed for the future building.

10. There are no instructions on the solicitation about how to register for the pre proposal and site visit.

Please, provide the instructions to register.

a. If you have missed walking the site and would like to schedule a time please give me a call at (340) 712-7747.
