SFO Superbay Hangar Feasibility and Fire Protection System Replacement

The Superbay Hangar is located in Plot 40 of the East Field at San Francisco International Airport (SFO). The hangar building systems and surrounding infrastructure are at the end of its remaining useful life due to continuous use and exposure to harsh and corrosive environmental conditions over the past 40 years. Through an on-call contract with SFO, K2A was asked to perform a comprehensive analysis of the occupied Superbay Hangar and the entire East Field. K2A Design Team evaluated the technical aspects of the current building and related site conditions. Our assessment involved field verification and review of record documentation provided by SFO.

The evaluation included building code, architectural and engineering analysis for HVAC, electrical, structural, plumbing, accessibility, roofing, elevators, building envelope, sustainability, and fire protection. At the same time, K2A conducted a comprehensive stakeholder engagement process to gather information on existing conditions, understand functional use, and determine current and future needs. The resulting comprehensive report became the basis of a program document that included design criteria, infrastructure requirements, site planning, enabling projects, engineering analysis, cost estimates, life cycle cost analysis, and construction phasing.

K2A was part of a design-build team to replace the Superbay Hangar’s fire protection system. The project included installation of a new fire alarm system, replacement of the hangar’s Tailbay sprinkler system, new diesel engine and fire pump, new 2000 gallon above ground fuel tank and day tanks, and recondition of six other fire pumps, as well as service of the existing protein foam and deluge system. K2A provided design for the new pump house.
