REQUESTS FOR INFORMATION (RFIs)

1. “Is this solicitation only available to WOSB contractors if this is the case do you know any that are bidding on this project so I may offer pricing?”

Government Response: Only Women Owned Small Business (WOSB) firms are eligible for consideration under this solicitation. The Government is unable to provide further information.

2. “The Drawings seem incomplete they ask to replace the riser to the existing meter structure per E4 and there is no E4 in the documents.”

Government Response: The drawings provided in RFP - Part 6 are "as-built" drawings from prior projects.

The drawings are not construction drawings for this project. They are provided to help give a general understanding of the power distribution system for the Lab Rec Area and Bldg. No. 216. Offerors shall not use the provided drawings as instructions for construction. The Designer of Record (DOR) will determine any required new design features. Reference RFP - Part 3 for project scope.

3. “There is no way to determine the length of the 4160v feeders from the drawings there are no site drawings with a scale nor any footages shown.”

Government Response: Offerors are responsible for identifying and verifying field conditions for construction. All relevant as-built drawings are provided in RFP – Part 6. The Contractor must connect the new 4160V circuit B from Manhole 6 to the new 4160V sectionalizing switch input way. The output way of the new sectionalizing switch must connect to the GFE "4160V General Electric Vacuum Limit Amp Control Panel" located in Bldg. No. 216's Compressor Room. The Contractor must connect the new 4160V circuit C from Manhole 6 to the new 4160V sectionalizing switch input way. The output way of the new sectionalizing switch must connect to the new 750KVA transformer. The Designer of Record (DOR) will determine any required new design features for connecting new 4160V feeders in Manhole 6.

4. “There are no drawings of the existing switchgear or pad to determine how large the new one should be.”

Government Response: Offerors are responsible for identifying and verifying field conditions for construction. Offerors may request for information and as-built drawings if they exist. The Designer of Record (DOR) will determine any required new design features for the new replacement equipment.

5. “There are no specifications for the new switchgear.”

Government Response: See RFP - Part 3 Section 2.0 “Project Objectives.”

6. “Are there back-up generation requirements the power will be out for a long duration when replacing this switchgear”

Government Response: Back-up generation is only required for the computer network equipment connected at a transfer switch, which is fed from a 3-Pole breaker at slots 43, 45, and 47 in “Panel A.” The system cannot be down and is backed up by a UPS for a maximum of 10 minutes.

Back-up generation is not required for 4160V compressor system.

7. “Specification section 00 10 00, Part 1, Item #8 (Instructions for Electronic Submission of Proposals) indicates to provide, “Completed provision(s) *” along with the contractors proposal. Are these the Reps & Certs? Please advise.”

Government Response: Yes, the requirement for completed provisions refers to the contractor’s representations and certifications.

8. “Part 3 Statement of Work/Project Program does not specify replacing feeder wires to various panels and equipment within the Building 216. However, at the site visit it was indicated that the feeder wires to various panels/equipment within the Building are to be replaced as indicated on the Power Single Line Diagram, Sheet E103. Please confirm.”

Government Response: Replace the existing branch circuit conductors from the secondary service switchgear to their respected panels and/or loads. Install quantity (2) spare 5” underground conduits from the secondary service switchgear to Bldg. No. 216. Reference UFC - 3-550-01: Exterior Electrical Power Distribution for spare conduit requirements.

Refer to response to Question 2 for RFP - Part 6 attachment "as-built" drawings for drawing references.

9. “Discussed at the site visit was a feeder circuit to an existing shed. However, the single line diagram (Sheet E103) provided with the RFP drawings does not show this feeder circuit. Please advise if this feeder circuit is to be replaced. And if so, please provide information on the wire size and feeder panel.”

Government Response: See response to Question 8.

The power service to the shed was recently installed and was not included in the as-built single line diagram.

Identify if the existing conductors are salvageable for utilizing at the new secondary service switchgear. If acceptable, utilize the existing branch conductor connected at 75 KVA transformer located in the existing shed when installing to the new secondary service switchgear. If replacement is necessary, size the conductor and circuit breaker accordingly to the existing system in the shed. The branch circuit from the secondary service switchgear serves a stepdown 75 KVA dry type 480V/208Y transformer.

10. “Please confirm that the equipment being replaced is limited to: 2ea—MV fused disconnect switches (HVS-2 & HVS-3); 1ea –Transformer (T-34); and 1ea—LV Service Entrance Switchboard and that only the feeder wires to other pieces of equipment are being replaced.”

Government Response: Yes, also include the material and equipment provided in the responses to Questions 3 and 9.

11. “During the replacement of the feeder wires to various panels and equipment, are there any critical pieces of equipment that must remain energized? Will short outages be acceptable without providing temporary power to specific pieces of equipment?”

Government Response: No. Short outages will not be acceptable. See response to Question 6.

12. “On a previous proposal, emailed proposals were acceptable. Please advise if emailed proposals are acceptable in lieu of submitting through PIEE.”

Government Response: Offerors should use PIEE to the maximum extent possible. However, if offerors are unable to use PIEE due to system error or inability to upload documents, submission of proposals via email are acceptable.

13. “When reviewing the existing transformer location and looking at the pad we notice there is no containment curb established.

a. When relocating the new transformer are we to include a containment basin within the new transformer pad?

b. Will this also require additional pipe bollards?

c. Are the new pipe bollards to match the existing in height above ground and the pipe diameter?”

Government Response:

a. Yes

b. Yes.

c. The Designer of Record (DOR) shall determine any required new design features.

14. “There is a small metal building to the Northeast of the transformer location with a power feed from the transformer.

a. Does that building need to remain energized during the disconnect and reconnect period?

b. What is the power draw for that building?

c. Can we get a picture of the electrical panel inside?”

Government Response: No, the building does not require back up power. Picture is attached and titled “Image - Shed Power Panel”.

15. “There is a tank located across from the transformer that we have been informed contains explosive materials.

a. Is that tank recharged through an underground piping system?”

Government Response: No, the tank is used for storage and has no connective piping.

16. “There is a large pile of debris across from the transformer location and between the explosive tank and the metal building against the fence that may hinder some of the work progress.

a. Are we to work around this debris or will the client have it moved?

b. Does the contractor move what needs to be moved in order to complete the work by relocating the debris to another section of the pile or is the contractor required to remove what the contractor disturbs?”
