A: Propane tanks, solvents for weapons cleaning, and paint spray cans will be stored in this room.

3) Q: Will munitions, including small arms ammunition, be stored in the proposed flammable storage room?

A: No munitions or small arms ammunition will be stored in this facility.

4) Q: What is the location/source for the main incoming electrical power to the facility?

A: A 167KVA (Primary 7,200 V/ Secondary 240/120 Volt) pad-mounted transformer exists

<100 feet west of the site and shall be upgraded under this project to support existing load and that of this project. See revised SOW for requirements.

5) Q: Will the main incoming electrical power be single-phase, or 3-phase?

A: Single phase power.

6) Q: What is the primary utility voltage at the job-site? Single-phase or 3-phase? Is the primary voltage base-owned or NV Energy owned?

A: See responses to RFIs 4 & 5. The primary voltage is owned by the base and is maintained by Creech AFB personnel.

7) Q: Will the incoming power to the facility need to be metered? If so, who will supply the meter? What type of meter will be required?

A: Yes. The contractor will supply a digital meter that is approved by NV Energy.

8) Q: Will the meter need to be remotely monitored?

A: No, that capability is not required.

9) Q: Will the incoming power be brought to the building underground, or overhead?

A: All power circuits must be underground.

10) Q: When the existing facilities on site are demolished, will the existing single-phase transformer remain in place?

A: The existing single phase transformer will remain in place when the “hooches” are demolished under a separate project because this transformer feeds the two PEBs (Admin

Facility & Training Facility) in the area. However, this transformer will be removed and upgraded under this project (RKXF 09-8017). See revised SOW for requirements.

QUESTIONS & ANSWERS

11) Q: What is the size of the existing single-phase transformer? If the transformer remains, would it possible to upgrade it, and use that to power the new facility?

Mode (SM) fiber optic cable and a 25-pair copper cable shall be installed from the existing manhole to the communications room of the new facility. Provide 40-foot extra loops in the manhole. Two (2) 4-inch conduits shall be provided by the contractor from the manhole to the communications room. A set of MaxCell 3-inch, 3-cell fabric inner ducts shall be provided in one of the 4-inch conduits. The other 4-inch conduit is a spare and does not require inner ducts.

A: Yes, just in the offices and classrooms. Provide “Blast Film” on the windows.

19) Q: If the power coming into the new Bldg is only single-phase then do you want to change the

HVAC requirement from current RFP to add smaller units to cut down on the initial power consumption?

A: The power coming into the facility is single phase only. We believe the largest single-phase

HVAC unit available is 5 tons. Providing a combination of smaller units to make up the required tonnage is acceptable. However, the total number of units shall be kept to a minimum.

20) Q: Are there any special requirements for the flammable storage area, i.e. additional HVAC, wall material, etc.?

A: As stated in the response to RFI #2, propane tanks, solvents for weapons cleaning, and paint spray cans will be stored in the flammable storage room. There are no other known special requirements.
