Curved Panels Help Jet Ranch Main Hangar Facility |
to Stand Apart
Ranch is a design-built, 82,400 square foot facility at the Carson City (Nevada)
Airport. 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 main hangar facility, the design team
at Licata Hansen Associates Architecture (Reno, Nevada) 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,” states 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 Company
(Eufaula, Alabama) and custom-curved by Curveline, Inc. (Ontario, California).
The main hangar utilizes about 14,600 square feet of curved “Standing Seam II”
panels with 24-in width and 3-in high ribs, in a SmartKote (Kynar® 500) cool
roof paint finish, color Regal Blue. Curveline curved the trapezoidal seam
panels in 10 different lengths up to 17-ft 2-in into precise radii that varied
from 18 ft 3-5/16-in up to 59 ft 4-1/2-in.
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-in rib spacing, manufactured by McElroy
Metal, Inc. (Adelanto, California). Eleven panels of 30-ft 7-1/2-in 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.
Curveline curved all panels to required specifications at its Ontario,
California service center and shipped them to the job site for final
installation. The company’s proprietary crimp-curving process increases the
strength and rigidity of panels, allowing curved roofs to be erected with
minimal framing. In addition, Curveline has the unique ability to shape panels
into multiple-radius forms such as the S-curves required for the canopy section.
Licata says: “The building team worked closely in a collaborative effort with
American Buildings and Curveline to achieve the desired effect. The result is a
very dynamic design that really stands out in the complex. The impact is also
strong from within the space, where the eye travels to the underside of the
curved roof form.” Licata reports that curved curtainwall is used to accentuate
the design theme inside the building, and a continuous catwalk underneath the
curved roof connects the public entrance to a mezzanine used for offices and
flight support services.
Valley Construction (Reno, Nevada) was the general contractor. Miles
Construction (Carson City, Nevada) provided and installed the pre-engineered
building and metal roof panels. Rollapart Buildings Inc. (Fallon, Nevada)
installed the exposed fastener curved canopy.
