The 40,000-square-foot (3,716-m2) Concord Jet Hangar in Concord, Calif., is designed for overnight storage of various aircrafts. The state-of-the-art corporate hangar was completed in March 2008.
The builder, Flory Construction Inc., San Leandro, Calif., worked with the fire marshal to have the hangar approved without foam fire protection. After extensive time and negotiation, along with the expertise of a specialty fire code expert, the hangar was built with water-only fire protection, providing significant cost savings over using foam fire protection. By building the hangar this way, it eliminated a collection pond and treatment of hazardous material should the system ever deploy.
Flory Construction utilized a pre-engineered metal building, roof and walls from Metallic Building Co., Houston, for the hangar. A metal building was chosen because it offered clear, open space in the hangar. The hangar features two 108-foot- (33- m-) wide hangar doors and a center jack beam to eliminate the center columns. The building has a roof slope of 1/2:12 and a 34 5/7-foot (11-m) eave height. Flory Construction used an inset/outset girt to create the relief line at the top of the door elevation. Metallic supplied 40,000 square feet of Metallic PBR roof panels, endwall panels and sidewall panels. The PBR panel system created an even-shadowed appearance that was important for the sleek, stealth-like image of the hangar.
The project also featured high-efficiency fluorescent lighting and complied with the California Clean Water Act.
Sam Moreno, Concord, was the architect; Hoffman Land Development, Concord, was the general contractor; and Shaw Structures Unlimited, Fresno, Calif., was the erector and roofing contractor.
