Norman Y. Mineta San Jose International Airport–CONRAC Garage
San Jose, Calif.
The nation’s first on-site integrated car rental and quick-turn-around (QTA) operations facility, this airport parking structure utilized double-tee precast design to shave more than five months off the construction schedule. Combining an eight-story, 3000-car rental-car parking area and a four-story QTA area including refueling stations and car washes, the facility puts rental cars within walking distance of the terminals. Precast components include double tees, L beams, inverted-tee beams, transfer girders, rectangular collector beams, columns and spandrels. To match the curved shape of the structure’s north end, both the shear walls and double tees in that area were curved, with the tees cast in pie-shaped wedges. Precast concrete spandrels serve as car-impact shields as well as a base skin for metal mesh and artwork murals. Precast was key to reducing first costs and construction time, handling seismic loads, providing a flexible design to enable post-applied architectural treatments, and allowing for easier construction on the congested site.
