About this file
This is a Questions and Answers document for federal contract 697DCK-26-R-00368, a FAA Chiller Replacement project. The document addresses ten contractor inquiries regarding project execution and requirements.
Key clarifications from the FAA include: asbestos surveys are required by the contractor, with abatement costs treated as contract changes; construction may proceed during cold weather with proper coordination; temporary cooling must maintain 72°F in occupied and critical spaces year-round; concrete pad extensions depend on new equipment manufacturer requirements; FAA badging is not required unless specifically mandated by the Contracting Officer, with FAA providing on-site oversight and escort; a prime contractor superintendent or delegated superintendent must be on-site at all times; all DDC system components must be compatible with BACNet-based protocols, specifically the current Distech Controls Niagara Framework system; all cold-water systems attached to chiller piping must be Test and Balanced, with existing TAB reports to be provided if available; glycol systems must be completely replaced with fresh glycol rather than reused, though the current volume is unknown due to incomplete piping documentation; and crane requirements and FAA Form 7460-1 necessity require additional information about the proposed crane specifications.

Questions and Answers
1. Does this project require Asbestos survey followed with removal? We would assume that any abatement required would be a change to the contract?
FAA Response: Although there is no expectation that asbestos will be present in the areas affected by this project, it is required that a survey be conducted by the contactor. If there are abatement costs because of the survey, those costs will be a change to the contract.
2. Period of performance / NTP clarification. Can this project begin construction during the cold weather months?
FAA Response: Yes, so long as the work is coordinated and properly planned to the satisfaction of the FAA Contracting Officer, Contracting Officers Representative (COR), and Local FAA Facility.
3. Does this project require any temporary cooling to the building while the main system is down.
FAA Response: Yes, even if the chiller is taken down during the winter, temporary cooling may still be required for equipment rooms. Contractor must maintain 72 deg F in all occupied and critical spaces during construction.
4. Do the existing concrete pads require extension?
FAA Response: This depends on the new, and approved equipment and the manufacturer’s requirements for proper and complete installation.
5. Restricted Area: With this building being secured, does this require personnel to have badging? This building is on landside and the chiller is on the exterior of the building not in a restricted area. If badging or escorts are required, we are assuming that the FAA will take care of either?
FAA Response: FAA badging for the contractor will not be required unless the CO specifically requires it. The FAA will provide dedicated FAA Employee(s) and/or FAA COR(s) to provide on-site contract oversite and escort the contractor.
6. Site Superintendent: During our site visit, the building personnel they would not require a site superintendent on site at all times. Would you confirm if this information is correct.
FAA Response: That is NOT correct, the local FAA facility does hold this contract for the FAA.
This FAA contract requires that the prime contractor has a superintendent, or delegated superintendent, on-site at all times.
7. Is the current DDC system up to date with new controls/control valves being installed?
Would the current DDC system need to be updated to communicate with new equipment?
FAA Response: The current DDC is Distech Controls Niagara Framework, which is a BACNet based DDC protocol system. The FAA requires that all DDC system components are compatible with and/or use BACNet based DDC controls. The contractor shall ensure all equipment installed for this project can communicate using BACNet based protocols.
8. Are there existing TAB records available? Is it required to only Test and Balance the new equipment to be installed per scope of work or does the entire facility need to be Tested and Balanced?
FAA Response: Currently, we are unaware if there are any existing TAB reports, they will be provided if they exist. All the cold-water systems attached to the chiller piping should be TAB’d.
9. Can the existing glycol system be pumped out, saved and reused. Can the
a. system be isolated and new introduced for just what was isolated and removed?
b. If the entire glycol system has to be replaced, do you have an approximate volume available?
FAA Response: Yes, please replace all the glycol in the system, new system should have fresh glycol. The current volume is unknown since we do not have accurate enough drawings of piping, sizes, and lengths.
10. Confirm crane requirements and whether FAA Form 7460-1 is required.
FAA Response: To answer this properly we would need to know more about the proposed crane you will require to complete the work.
