Case Study

Department of Transportation
Salt Storage Building

21,600 sq ft Tension Fabric Building for DOT Salt Storage
Oakdale, Minnesota

MN Department of Transportation - Project Profile

The Rundown

This salt storage shed is designed to last in a corrosive environment with a hot-dipped galvanized rigid frame and a passive ventilation system to prevent moisture build-up. Concrete retaining walls increase the bulk salt storage capacity and protect from accidental collision.

Customer Success

“It was a priority to get the new building operating quickly so we could continue our programming. They were totally committed to doing whatever was necessary to support our project.”

Steve Henry | OKC Tennis Center

“Legacy Building Solutions has given Solar Ship more than just a state-of-the-art hangar and assembly building. Through our close collaboration, their design incorporates a self-reliant photovoltaic power package that sits above the fabric roof, allowing our building operations to be entirely off-grid. In addition, Legacy’s foundation design allowed us to re-use an existing concrete pad, saving us time and money during construction. These innovations were part of our top-level requirements, and delivering on them really sets Legacy apart from the traditional building segment.”
