W50S85-22-Q-0013 Electrical Lateral Utility Investigation - MV Feeder Raceways & Manholes as of 23 June 2022 @ 2:11pm

Dated: 7 June 2022

Q1. If you look at the drawing + 1+12+2022. I see 34 Red Boxes highlighted in yellow. What does that signify?

A1. There are 36 locations signified by numbered Red Boxes highlighted in yellow. Each test location is 3 conductors in accordance with the “Description of Service”. Example: (MV switch-to- MV Switch, MV switch to MV side of Transfromer) need to tested under this contract.

Q2. Also, just feeder #1 (shown in dark red). How many individual cable tests?

A2. Yes, feeder #1 shown in dark red,Total 36 MV cable test locations with 3 conductors each plus grounding test at each location.

Q3. I also see a sample report from the Detroit Arsenal. Is that how you want the cables tested at Selfridge?

A3. Test report not found, Submit test report IAW the Description of Service.

Q4. Please advise regarding the method / means for obtaining the specifications and drawings for this project. The response to RFI: question Q1 references drawing 1+12+2022.

A4. The drawings are an attachment in the SAM system, file name, “Drawings 1 Apr 12 2022 update”

Q5. Will you provide a SF1442 for this project?

A5. No, attachment “22Q0013_Combined Synopsis Solicitation” states “This announcement constitutes the only solicitation; quotes are being requested and a written solicitation will not be issued.”

Dated: 9 June 2022

Q6. Can this work be performed during normal business hours? Also, can we test all 34 locations simultaneously having several test sets. This would require Feeder 1 to be shutdown.

A6. Can this work be performed during normal business hours?

Response: No, this work can not be performed during normal business hours since the Base is completely operarional M-F during normal business hours and MV Feeder 1 feeds lots of mission critical loads so MV feeder 1 can not be shutdown during normal business hours.

Also, can we test all 36 locations simultaneously having several test sets. This would require Feeder 1 to be shutdown.

Response: There are 36 numbered locations for testing, Generally VLF testing can take 1 hour per cable. With several test sets a testing firm may accomplish much of the task per outage event. The base (customer) will need coordination for the shut down events and announcements will be made via public affairs. Please read all accociated documents, IE: drawing and PWS (Description of service).

Q7. Will the base allow the contractor to pump out the man holes the day before the scheduled shutdown.

A7. This contract does not expect to pump out manholes, if needed base will allow the contractor to pump out the man holes the day before the scheduled shutdown, The contractor shall follow all OSHA lock out and tag out procedures and disconnect the supply from the switch hose bldg. 854 and disconnect the MV feeders from MV transformers and Load Break switch and test all drops mentioned on the drawings.

Q8. Has the owner identified any manholes deemed to be unsafe to enter while the cables inside them are energized.

A8. The owner has not identified any manholes deemed to be unsafe to enter while the cables inside them are energized. The contractor shall not perform hot any work. The contractor shall coordinate with the Base personnel and follow OSHA safety lock out and tag out procedure and shut down the electric supply before performing any work.

Q9. Who (Contractor or base personnel) performs the switching operations during switching activities.

A9. Contractor shall coordinate with base personnel and perform the switching operations during switching activities. Feeder will be locked out for testing.
