10. The new sub CH-1 shows new conduit and wire to building 11 to 800 amp CB, chiller mcc, and chillers 1 and 2…Can you please provide a drawing showing locations of equipment so that we can scale off lengths?

Reference Drawings E108 and E109: Delete the requirement for replacement of new conduit and wire from new unit substation CH-1 into Bldg 11. The existing conduits and feeders will remain in place and will be re-terminated on the new unit substation secondary switchboard circuit breakers.

11. Drawing asks for communications cable to be ran through boiler building 11… Can you please provide a drawing showing location of this room to be able to figure out conduit and wire lengths?

For the communications cable requirement please include 120 linear feet of 1” galvanized rigid steel conduit, 6-90 degree elbows, 3-6”x6” pull boxes (indoor), and supports as per NEC requirements.

12. They have in the spec about alternate 1 as being a cost for sub CH-1 switchgear... the original drawings before addendum 1 called out for this gear just to be painted and new high voltage feeder to it… Then, the addendum 1 came out and had this as being new gear and new feeders, wire to the 2 chillers a 800 amp CB, and a mcc nothing on drawing saying it was an alternate .

My question is if the VA does not take the alternate, what is the scope of work to be included in base bid?

As a clarification: Alternate No. 1: The replacement of unit substation CH-1 is a bid deduct therefore the replacement should be included as part of the base bid. No new conduit and feeders are required under either the base bid or alternate no. 1 as per the response to question 10 above.
