Hangar takes distinct aerodynamic form

Jet Ranch is a design-built, 82,400-square-foot(7,655-m2) facility at the Carson City Airport in Nevada. The multi-building complex features customized aircraft hangars available for lease and a main hangar that is privately held for use by the owner. In planning the 34,214-square foot (3,178-m2) main hangar facility, the design team at Licata Hansen Associates Architecture, Reno, Nev., wanted to create a building that would stand apart visually from the leased hangar space and would also have the ability to house larger aircraft.
“We decided the building should have a distinctive shape that would reflect the aerodynamic concept of aircraft, so we designed the roof structure to mimic a wing form,” said Ric Licata, AIA, project architect and principle at Licata Hansen Associates. A segmented brace frame steel structure supports the concealed fastener roof panels, which are laid end-to-end over purlins to cover the large span of the building. The roof design uses straight panels starting from one eave and sloping upwards into a series of curved panels that reach a pronounced downward arch at the opposite eave. One corner of the building at the arched end also has a public entranceway topped with a piano-shaped curved panel canopy that further extends the aerodynamic theme of the design.
The 24-gauge steel roof panels were manufactured by American Buildings Co., Eufaula, Ala., and custom-curved by Curveline Inc., Ontario, Calif. The main hangar utilizes about 14,600 square feet (1,356 m2) of curved Standing Seam II panels with 24-inch width (610-mm) and 3-inch (76-mm) high ribs, in a SmartKote Kynar 500 cool roof paint finish, in Regal Blue. Curveline curved the trapezoidal seam panels in 10 different lengths.
For the piano-shaped entranceway canopy, the project team needed a panel with the capability to be double-curved into an “S” shape. The panel chosen was a Mega-Rib exposed fastener panel with 7.2-inch (183-mm) rib spacing, manufactured by McElroy Metal Inc., Adelanto, Calif. Eleven panels of 30-foot (9-m), 7 1/2-inch (191-mm) length were concave- and convex-curved into two different radii and angles of curvature to form the uniquely shaped canopy cover. The panel finish and color were the same as the main roof section.
Valley Construction, Reno, Nev., was the general contractor. Miles Construction, Carson City, provided and installed the pre-engineered building and metal roof panels. Rollapart Buildings Inc., Fallon, Nev., installed the exposed fastener curved canopy.
