QUESTIONS AND ANSWERS

407 and 421 Hangar Fire Alarm System W50S9J-26-B-A010 1679 Coonskin Drive Charleston, WV

1. Will the Government consider a design that does not reuse the existing Siemens panel in Building 407, but instead replaces it so that both Building 407 and 421 are served by a single, unified Potter fire alarm and mass notification system?

· If allowed, are there any constraints (e.g., existing base‑wide monitoring infrastructure, network compatibility, or standardization with other base facilities) that we must specifically address in our design narrative and submittals?

· An acceptable “or equal” system substitution under the current solicitation, provided we demonstrate full compliance with all code and UFC requirements and functional equivalency/improvement; or

· A change that would require a formal modification to the SOW?

Answer: Bidders are to submit their bids based on the original Statement of Work posted to SAM.gov on 12 May 2026.

2. Regarding the NTP and 90 days for completion, is the government willing to work with the winning bidder for an extension on the period of performance due to possible supply chain delays?

Answer: Yes. The government understands the delays and will work with the contractor. Please advise as soon as possible of any delays.

3. Is the contractor to install heat detectors that are addressable or conventional wired as a single zone to an addressable system using an initiating Device Circuit Monitor Module?

Answer: The heat detectors installed will be addressable.

4. Will the aircraft be in the hangar during the installation process?

Answer: Yes, it is a possibility. The contractor will work with Maintenance leadership to deconflict. Aircraft maintenance is scheduled months in advance. They will also work with the contractor for any unforeseen maintenance requirement for day to day operations.

5. Is the existing conduit being used?

Answer: Yes. Contractors are to use the existing conduit.

6. When using a lift in the hangar, what height has been used for previous work?

Answer: 75 feet but contractor will need to verify.

7. In reviewing the Statement of Work and accompanying drawings, we request the following if available:

Complete Fire Alarm Drawings

Please note that there are no Sector 1 and 2 drawings and it appears that portions of Sectors 3 and 4 may not be complete. We would like to request a review of the drawings package and issuance of any sheets (sectors) which may be available but were not included in the original package provided on SAM.gov.

Answer: All sectors are available for both buildings on the drawings uploaded to SAM.gov. Sector 1 and 2 are FP building 407 page 2 and 3 respectively. Sector 3 is all there on FP building 407 page 4 and Bldg 421 page 6. Sector 4 is provided on FP building 407 page 5 and Bldg 421 page 5.

13. . Please confirm which existing devices on the provided fire alarm/MNS plans are “conventional” and are to be removed and replaced under this project

Answer: All devices shown on plans are conventional and to be replaced.

14. Are the conduits/raceways serving the conventional devices dedicated solely to those conventional circuits, or do they contain any wiring associated with the existing Siemens addressable system in Room 137, Building 407?

Answer: Yes, the conduits serving the conventional devices are solely to those conventional circuits, and do not share wiring with the existing siemens addressable system in Building 407.

15. If any raceways are shared with Siemens wiring, will temporary interruptions/controlled outages of Siemens circuits be permitted during demolition and installation, and are there any restrictions (hours, coordination requirements, etc.)?

Answer: interruptions and outages of the fire alarm and MNS system will be permitted during the contract period.

16. Please provide any available Siemens system drawings (riser diagrams, device layouts, NAC/MNS layouts) and a current point list so we can understand what devices and functions are being served by the existing Siemens panel in Room 137, Building 407.

Answer: No additional drawings will be provided during the solicitation.

17. Please confirm whether the existing Siemens panel currently supervises or controls any devices in Building 421.
