MEMORANDUM FOR RECORD

SUBJECT: Relocatable Simulator Shelter Request for Information (RFI) Questions & Answers

a. An RFI was posted to Fed Biz Ops on 9 Apr 2018 for the subject requirment. The questions below were received as a result of the post.

b. The following questions were asked:

1. QUESTION: Reference Table 8.1. Space Requirements on page 6 of 8. Question: Can the

Government please clarify the requirement for the debrief room to be 150 feet from the BOWST host cabinet? It seems this would put it outside the structure.

RESPONSE: The debrief computer (debrief area) needs to be no more than 150 feet from the trainer. The debrief area will be a desk, computer, and chair. It can be placed closer to the

BOWST host computer cabinet, and does not need to be a separate “room” as such.

2. QUESTION: Reference Table 8.1 Column Intrusion on page 7 of 8. Question: Is the BOWST main area the space covered by the Trainer: 23’ W x 22’ D x 19’ H??

RESPONSE: Per the Facility Design Criteria, “The BOWST and computer rooms shall be column free.” The BOWST main area would include the area covered by the trainer and space for maintenance access. So, from table 8.1, Space requirements, the column-free space in the

BOWST Bay should be 1156 sq. ft.

3. QUESTION: Reference Table 8.3 Fire Suppression on page 8 of 8. Question: Is the equipment sensitive to water? If so, would you rather have a chemical solution or a dry suppression system?

RESPONSE: AFI 91-203 requires an automatic sprinkler system for all Flight Training Devices and other High Value Training Devices (45.3.2.3.1) installed IAW UFC 3-600-01. UFC 3-600-

01 will reference ETL 01-18 for fire protection criteria for Air Force facilities. I am awaiting some clarification from the 100 CES/CEF Fire Chief on the sprinkler requirement.

4. QUESTION: Reference Table 8.7 HVAC on page 9 of 8. Question: We would need more information in order to size and plan for the HVAC. For example, can we put the cooling into the raised floor like in a data center and bring the air up through vented tile locations? How much tonnage is required to cool the equipment/people in this room? Lacking the tonnage specification, we would need specs on the equipment in order to do the tonnage calculations ourselves.

RESPONSE: Raised floors cannot be used in the main BOWST area as the estimated total trainer weight is 20,000 pounds, with a maximum live load of 2500 lbs. The BOWST must be mounted directly to the concrete pad at 10 locations, using three concrete anchors embedded/chemically fastened to each mounting location imposing a maximum load of 47 PSI.

- Raised floors could be used in the computer room area as long as the floor is rated to handle

100 lbs rolling load and 250 lbs concentrated load. The total estimated weight in the computer room is 2000 lbs

- The following BOWST equipment heat loads have been calculated:

- Trainer total heat load: 36,094 BTU/hr

- Off-board equipment total heat load: 27,903 BTU/hr

- The total heat load generated by the BOWST with 3 people inside: 64,000 BTU/hr

5. QUESTION: Some trade professionals necessary to perform some of the work outlined in the requirements, may not have security clearances. Is it possible to allow a certain ration of cleared personnel uncleared, but escorted personnel to perform on the contract.

RESPONSE: Yes this is possible, but the contractor will have to coordinate the times with the customer what dates and times escorting will be necessary.
