Ingenium Mechanical Design Group LLC specified

standing seam panels for gabled roofs on six flight

line canopies owned by Nellis Air Force Base and

Nevada Air Combat Command Department of

the U.S. Air Force in Las Vegas. The metal panels

replaced fabric enclosures, which required repairs

and replacement due to damage from daylight and

wind. The structures’ main framework was re-

moved and replaced as needed.

PVB Fabrications Inc., general contractor and

installer for the project, installed 140,400 square

feet of McElroy Metal Inc.’s Masterlok-FS standing

seam roof system in Travatan. The panels were pro-

duced with a 24-inch minimum width and 22-gauge

minimum of galvanized steel. They have a factory-

applied bead of elastomeric caulking.

The standing seam panels are continuous from

roof ridge lines to drip edges. They are secured to

steel purlins and roof beams with metal floating

clips that allow for expansion and contraction during

temperature changes. McElroy Metal supplied the

purlins and PVB Fabrications fabricated frames and

columns. The roof panels extend 2 feet beyond gird-

ers to provide overhanging eaves, and the gutters

have EPDM lining.

The flight line canopies have overhead and

side-mounted lighting, powered by underground

electricity and outlets. The project was completed

October 2017.

Moser Roofing Solutions installed a metal roof over

an existing metal roof at OST Trucking in Balti-

more so operations could continue running during

construction. The 68,000-square-foot project uti-

lized EXCEPTIONAL Metals’ EM Retro-R metal roof

panels in White and 50-mil Duro-Last membrane in

White. Moser Roofing Solutions received five 2016

Duro-Last Project Awards for the trucking ware-

house. It was completed in August 2016.

To accommodate the installation of eight,

full-size flight simulators at American

Airlines Training and Conference Center

in Fort Worth, Texas, a section of insulated

metal panels (IMPs) was removed from the

newly constructed building. The airline train-

ing simulators are large, the same size as

the front end of airplanes. Trainees enter the

cockpits via a landing on the second floor

inside the building. The simulators are for an

Airbus 320, McDonald Douglas 80, Embraer

ERJ 145 and five Boeing jets: B-737, B-757,

B-767, B-777 and B-787.

Keith Tucker, construction manager

at Southwest Vault Builders, says, “They

wanted the building completed and sani-

tized prior to the simulator installation. With

the concealed-fastener insulated metal wall

panels, they started at the top, unscrewed

the fasteners and then worked their way

down to the ground. Once the simulators

were in, they reinstalled the removable wall

panel section.”

Southwest Vault Builders Inc. installed approxi-

mately 30,000 square feet of Green Span Profiles’

3-inch-thick, R-24 IMPs in custom American Airlines

Tan on the exterior and Regal White I in the interior.

The design utilized 30-inch-wide and 36-inch-wide

panels to align panel side-laps with window sec-

tions. The IMPs were installed as walls on the first

two stories. The lowest windows were installed

about 8 feet above the start of the panels that were

removed and reinstalled. The 16,358-square-foot

project was completed in June 2015.
