Q15 We have some experience with this hangar from 2016 and at the time, some of the MANG members had some unrealistic expectations on how air tight rolling steel door can be. The doors all had baffles, bottom seals and guide brush seals as specified but rolling steels doors are by their nature, leaky when compared to sectional doors. Once we started Door Systems, we addressed the job that Wally’s Overdoor installed and added some extra rubber guide seals and caulked the guides to the walls on the tire shop (B101C) as an experiment in air infiltration. They were better but still leaky as coiling doors are. B-103A is also a special case as it is a door that needs to drop automatically in case the foam fire retardant system is triggered to contain the foam from going outside the building. Because it needs to drop automatically, that door cannot have seals with too much friction against it or it will not drop. That door has a special operator tied into the foam system and the fire alarm. If we could do a site visit to get all the serial numbers from the existing doors and have a meeting about realistic air infiltration expectations, we could then provide a bid to add extra seals to those existing doors.

A15. This is an acceptable approach. During the B80 project in 2020 this door, seal, and baffle work was completed on the exterior roll up doors with great success.

Q16. Per sheet E1.03, Flag note 28 states to re-certify building 25 and 80 however during our site inspection we were not asked to inspect building 80 and there is no direction in the bid documents. Assuming both building have current certification, we recommend the certification by the Underwriters Laboratory be a limited scope inspection for the roof top only, since the work being done is a re-roof and only rooftop lightning protection will be worked on. Is this acceptable?

A16. Yes, that is acceptable. Building 25 and Building 80 each have separate certifications. Only the B25 new lighting protection system will need to be recertified.

Q17. Keynote #6 on A1.20 states; “Remove all equipment and furnishings as required.” This note pertains to numerous rooms. Where will the contractor be required to move the equipment and furnishings to? Is the contractor required to move and reconnect equipment and furnishings afterward?

A17. The Government will remove and reinstall the equipment form the areas where the floor coating work will occur.

The Military expectation for FOD and Garbage is, " If you see it pick it up and dispose of it properly is a container."

Any loose garbage not only affects the MT ANG but also the Great Fall International Airport and FedEX.

Q25. Fire sprinkler modifications: There is a conflict between A2.10 and F1.00 regarding how many rooms are incorporated into the work area. Please advise.

Flag note 215 on page E1.01 calls for 5 receptacles and data outlets, there are 9 of each on the drawing in room B242. Are the 5 of each in the flag note additional? Can I get a business name and contact number or email who installed the current lightning protection system?
