Fabric building is a convenient home for city buses in the Hawkeye State
Davenport, Iowa, opened a new bus storage facility for their CitiBus public transportation system this past May. The tension fabric structure was designed, manufactured and installed by South Haven, Minn.-based Legacy Building Solutions.
Prior to construction of the facility, Davenport’s buses were housed in a large building across the Mississippi River in neighboring Illinois. The new garage keeps the buses housed locally, under the control of Davenport’s public works department.
“Our transportation system requires the diesel buses to be stored in a facility to keep them warm and protected from the elements,” says Joe Balge, design and construction coordinator for the Davenport Department of Public Works. “Legacy’s customized fabric structure design was able to fit our purposes.”
The building features a fire-rated, 15-ounce fabric roof attached to a solid steel frame. The structure measures 300 by 70 feet, with a peak height of 31 feet, 4 inches. The facility can hold approximately 25 buses at one time. Each endwall of the tension fabric structure features three doors – two 16-feet-wide by 13.5-feet-tall, and one 20-feet-wide by 13.5-feet-tall. The building’s design allows buses to enter on one side and exit out the other.
The heated fabric building also includes R25 fiberglass insulation. Its temperature is maintained around 50 to 60 degrees during the winter. A portion of the roof at the peak is non-insulated, providing a fabric skylight area for natural sunlight to enter during the daytime.
Other building features include primed steel components, 18-inch overhangs with mesh soffits, and sprinkler and lighting systems hanging from the steel I-beam framing.
“It was a good experience working with Legacy,” Balge says. “Their in-house installation crew put up the building very quickly. They’re easy to work with and willing to help, and the communication with the city and responsiveness throughout the project was very good.”
