As-built drawings can be provided by the Contracting Office for use and review. Contractor must field verify all existing conditions.

37.

High Expansion Foam System - The drawings indicate to remove the existing High Expansion Foam System and install new. However, the bid package includes a sundown policy letter indicating High Expansion Foam systems are to be removed from DAF Hangar facilities. Will a new High Expansion Foam system be required for this project?

No, a HEF system will not be installed. Revised Drawings/Specs are being finalized.

38.

High Expansion Foam System As-Builts - Are as-built drawings (showing the existing pipe sizing, pipe layout, foam generator locations) of the existing high expansion foam system available? These would assist with determining how much of the existing piping can be reused to accommodate the new foam generator locations. Alternatively, if the system is no longer required it will assist with determining the extent of the demolition work required.

Contract documents have been updated to require the high-expansion foam system to be demolished in its entirety. This has been updated as part Addendum No. 01, dated 2 May 2022. Please see Addendum No. 01 Fire Protection Plans. As-built drawings can be provided by the Contracting Office for use and review.
