PROJECT DESCRIPTION
This project involves the fire suppression retrofit of the hangar bays of Building 912 located on the Joint Forces Training Base in Los Alamitos, CA. The Group I aircraft hangar bays (approx. 50,000 sf total) house both fixedwing and rotary-wing aircraft. The existing fire suppression system to be removed utilizes aqueous film forming foam (AFFF) distributed through an overhead pre-action closed head sprinkler system, 6 floor-mounted oscillating monitors and 2 manual hose reels stations. Features to be removed include; 1 AFFF concentrate tank, 2 concentrate pumps, 4 pre-action risers, overhead sprinkler system, all oscillating monitors and hose reel stations, all associated fire suppression piping and fire alarm / flame detection systems.

The new system to be installed within the hangar bays shall be a combination of automatic wet-pipe sprinkler protection and an automatic low-level high-expansion foam system. The system shall be compliant with current DoD Unified Facilities Criteria (UFC) and National Fire Protection Association (NFPA) requirements including but not limited to UFC 3-600-01, UFC 4-211-01, NFPA 13, NFPA 409, NFPA 11, NFPA 20 and NFPA 22. The project will also involve the installation of two above-ground water storage tanks (approx. 135,000 gal. each), a co-located fire pump house, an electric- or diesel-engine driven fire pump (approx. 4,000 gpm, 130 psi.), modifications to the existing fire water distribution system beneath hangar floor, upgrades to the existing electrical distribution system, and installation of criteria complaint fire alarm system.
