RFI Questions and Answers

Several notes on the drawings show electrical circuits being demo d back to source. Shouldn t we keep these to re-use for the new circuits?

For the bid purpose. demo the existing circuits back to the source. More determination need to be made in field during the demolition and be coordinate with the COR.

There are several locations on the drawings showing circuit homeruns (are these dedicated, do existing panels have spares) but no numbers or panels. Can we have some clarity on these?

Any new homerun circuits shall be go to the same panels as the existing circuits for these rooms. For room 116-B, the panel is 1NLB-3 and for room 136-b and 137-B, the panel is 1NLB-1. Contractor to include new Circuit breakers for the panels.

Drawing ED-100 shows the call stations to remain and be protected throughout. Are these be removed at all or just left alone and covered?

Left alone and covered during the construction. Contractor to protect the call stations.

There are conflicting notes on the x-rays and who is responsible for final connection/termination. Are Xray s 1 for 1, existing power? Is this the VA or electrical contractor?

The X-ray for room 116-B is new and Contractor to provide new power to the X-ray and final connection and termination by others. The other rooms are replace existing x-ray units with new ones and contractor to modify and re-use the existing power, final connection and termination by others.

What is your proposed path for the new feeder conduits between the existing risers and the new panels? Typically, the halls are extremely difficult to get any conduit in, let alone multiple large feeder conduits. Are any drop ceilings being removed for the new feeder install?

The proposed path for the new feeder through the halls. It should be enough room to run new conduits. The contractor shall be responsible to remove the ceiling tiles as necessary to run the conduits and install them back. Knowing that, ICRA plan shall be maintain during removal the tiles.

We have a couple questions regarding Drawing E-103. We want to clarify the wire and conduit sizes are shown correctly between Riser 61 & Panel 1NLB2 and also between Riser 81 & Panel 1NLB3. In the pictures, the wire sizes appear opposite than what is drawn.

Since the wires/Conduits between the two risers and the existing panels are exist to remain. There is no effect on the Bid. Further discussion can be made on field during the construction with the COR.

In the feeder size schedule on drawing E-105 it shows using full size grounds. (The existing feeders have no equipment ground wire, using conduit as ground please provide detail on this grounding situation IE. ground bushings and ground bar, also use NEC for proper ground sizing for new feeders and loads.)

The contractor shall be responsible to use the proper size of ground wire by NEC. Provide new mechanical ground lug inside the existing J-Box for the risers and the new Panels. Also ground bushings are required for the new feeders and should be connected to the same ground lug inside the J-box and new panels.

The Phasing Schedule on drawing R-1 is confusing. Are these 4 phases to be conducted at different times from one-another or at different locations from one-another or both? Also the phasing within Phase Four on drawing A-107 is further confusing. Please elaborate on the meaning of phasing as used in this design.

There are 4 separate phases for this project. Each phase shall be finished before move to the next phase. Refer to sheet R-1 for exact details about the phases.

Is it the intention to perform the work in Room 116-B at a different time from 136-B and 137-B? Or can they be concurrent?

There are 4 separate phases for this project. Each phase shall be finished before move to the next phase. Refer to sheet R-1 for exact details about the phases. Further discussion can be made in field prior to start the construction with the COR.
