The 16,320-square-foot (1,516-m2) Spring Valley Gym in Spring Valley, Calif., utilized Oklahoma City-based Star Building Systems’ StarShield Roof System along with StarMark Wall System. Completed in September 2007, this gymnasium and teen center provided many design challenges due to the large clear spans with heavy seismic loading, along with sidewall and endwall lean-tos that attached to the main structure, as well as each other with hip and valley conditions. The building had four eave heights and three materials on the walls: StarMark, studs and stucco, which had to be integrated together. Steal bond beams were used on the lean-tos to carry the metal studs and stucco.
The main building, 101 by 120 feet (31 by 36 m), supports more than 5 tons (5 metric tons) of equipment. In addition, soffits were added with special box flashing on the lean-tos to the sidewall canopies and gable overhangs to accommodate the stucco walls. Portal frame bracing was used for the interior room requirements of the building. Star Buildings designed special slotted connections in areas of the structure to handle the diversity of movement by the different buildings and materials. A Star Standing Seam Roof was installed on the tube steel entrance canopy so the structures would blend together. The erector/builder on the project was G & W Builders Inc., Brea, Calif.
