Jewel Cave HVAC System Replacement Questions and Answers 2

1
On drawings number 43 it calls out 3 panel locations for “G” “P1” and “V” but does not show where those are located. We believe these are locations separate from the rest of the building but are not sure. Could you tell me where these 3 panels are located?
Panel G, and P1 are located in separate buildings but are fed from the Visitor Center basement. Panel V is fed from the Kiosk(P1)

Is that the specs call out to save as much conduit from these 3 panels as possible so we need a rough distance to the length of the conduit in order to get an accurate material price. Even if you just had the distance from each building, we could use that as a rough estimate.
The new Panel “MDP” is in the same room as the above mentioned Panel G and Panel P1. Panel V is a non issue because it is fed by the Kiosk. The total distance for rerouting etc. will not exceed 50 ft.

The specs in the drawings on call out to match the existing tile but do not call out what material it is
The ceiling tile is your standard 12" x12" acoustical ceiling tile. The ones that are in the VC are older and we realize they won't match the existing perfectly. I have attached a picture. This should be a good start for the contractor. When they send submittals for tiles we can approve at that point.

On page 45 of 45 it is not listing the AIC rating and will need that to determine what MDP to acquire
42kAIC.
