QUESTIONS ASKED DURING THE WALK-THRU:

Q1) Do we need to submit to Michigan Licensing and Regulation Agency (LARA) or is the DMVA submitting to LARA?

A1) No, neither the bidding contractors nor DMVA need to submit to LARA. Medium Voltage projects are not submitted on.

Q2) Does this project require aluminum or copper medium voltage cables?

A2) Refer to specification section 260513 (2.01) (A) (1). Copper was incorrectly stated in the Pre-bid meeting. Note: the concentric neutral conductors on the MV cable are copper.

Q3) Fiber optic cable; will that be supplied by the DMVA or the contractor?

A3) Refer to specification section 271323 (1.2) (A) and (2.3) (A & B). This item would be provided and installed by the contractor. This fiber optic cable shall be blown or jetted into a micro-duct system and pulled in the final length of the 2” PVC raceway and into the Weapons Cleaning Building.

Q4) Who provides the underground fiber optic duct?

A4) Depends on the project location. A length of armored microduct (seven individual microducts bundled in an overall jacket) is supplied by the DMVA (approximately 1185 feet, located at the main camp, to be moved to the site by the winning contractor) and installed the contractor between vault V4 and V7. Between vault V7 and the handhold HH-A, the contractor provides the two (2) 2-inch schedule 80 PVC raceways.

Q5) What does this temporary transformer site on, a fiberglass box pad or a concrete slab style pad?

A5) A fiberglass box pad will be supplied by the Weapons Cleaning Contract. This item was incorrectly stated provided by this contract at the Pre-bid meeting. It is not provided by this contract.

Q6) What is the size of the “Temporary transformer” located at the Main Camp to be moved by this contract to the site to power-up the Weapons Cleaning Building until their transformer is delivered?

A6) The temporary transformer located in the “bullpen” near building 36 has the following size information:

1. 75kVA.

2. 66” wide x 38” deep.

3. Primary side: 14400/24940GRY/14400

Secondary side: 208Y/120 volts.

4. 2505 lbs.

Q7) Are the medium voltage (MV) cables supposed to be in duct of direct buried?

A7) Direct bury is allowed.

Q8) Is plowing-in the MV cable allowed or does it have to be open-cut trenches.

A8) Plowing-in the MV cable is allowed, however the fiber optic micro-duct bundle is to be laid nearby per the detail shown on sheet E1, “Cable Trenching Section”.

Q9) Do the existing vaults have water in them?

A9) As part of this meeting we drove around the site, opened one of them, and it did in fact have water in it.
