San Francisco International Airport Superbay Hangar
San Francisco, CAThe Weitz Company has overseen the programming, design, construction and commissioning services of this complex, multi-phased project for the San Francisco International Airport that is replacing all of the wet and foam fire suppression systems in the 420,550-square-foot hangar. Overall, there are approximately 5,000 sprinkler heads throughout the hangar. The foam system has 48 foam generators that suppress any fuel-fed fires (9-12 feet of foam can cover the hangar floor in just three minutes) designed to stop fires from the bottom up. The wet sprinkler system is approximately 120 feet from the finished floor, which is the height of the inside of the hangar.
In addition to the fire suppression systems, Weitz is also building a new pump house with fire pump equipment; new generators; two new fire water supply tanks; and new industrial waste system and tank.
The superbay hangar, which is one of only four in the United States that can house four 747 aircrafts, remained occupied during construction. American Airlines and United Airlines continued to perform critical and necessary aircraft safety and maintenance checks during off-peak hours, which Weitz coordinated daily with the airlines.
To execute the project, Weitz is scheduling construction around the occupants’ work schedule. The coordinated approach allows the tenants to continue to use the Superbay Hangar during the renovation process and will expedite the hangar fire suppression system update. Airplane maintenance work is occurring at night with construction work being performed during the day. The Weitz project team coordinates a stand-up meeting every morning with American Airlines and United Airlines so they can discuss the day’s plans. This ensures the construction team is out of the way of airport staff by the time their evening shifts begin.
