Lockheed Building 153A Solar Array Test Facility, Sunnyvale, CA

This structure is a 180’x105’ high-bay clean room for testing satellite solar array panels. Biggs Cardosa designed the building using structural steel framing, including the 105-foot clear-span roof trusses which were designed to support the roof, catwalks and 30,000 lbs of mechanical units, and to act as portal frames for additional building rigidity. The project included four one-ton monorail hoists on curved tracks to support panel testing equipment.
