• Do we have a Geotech report for the area, especially where we are boring?
Answer Limited geological information is available. Reclamation excavated two test pits at the approximate locations shown below for the purpose of determining soil percolation properties.
The backhoe encountered stiff soils (hardpan) at a depth of 3.5-4 ft. The final photo shows the bottom of excavation.
• Do we have a wall section for the building, or a detail from the existing buildings? The specs are talking about a pre-engineered steel building with steel stud framing. Just want to confirm what the walls/roof look like
Answer A typical wall section was not provided in the drawings. The detail at right shows a typical wall. Please note, there is no interior finish. Specification section 13 34 20 paragraph 2.07 B has been revised as such and included as part of this amendment. Roof is similar with sheet steel exterior and vinyl backed insulation held in place by purlins.
Electrical Questions:
o Can you confirm the size of the transfer switch, the photos are blurry when you zoom in.
See attached Informational Only Drawings ST111 & ST112 o What device is the transfer switch feeding and are we refeeding that piece of equipment or is that power being repurposed solely for the new building?
See attached Informational Only Drawings ST111 & ST112 for devices being fed. Also note that Drawing # 894-417-733 states “reconnect existing building”.
o There is no panel schedule or equipment schedule with loads of the new equipment, can we get loads and power requirements of the equipment going into the new building?
o They did not say which size the new panel is to be, only that it has to be sized per the NEC, which we can't do without knowing what we have to feed from it and also if the proposed power from the transfer switch will be of the appropriate size to do so.
See one line diagram below.

Sheet steel
Plumbing Questions o Sounds like the park supplied some of the equipment for the last decontamination building. Just wanted to confirm this isn’t the case for this building.
All equipment is to be provided by the successful offeror in accordance with contract documents.
