Case Study

Basin Electric Power Cooperative
Bottom Ash Dewatering Facility

52,800 sq ft Tension Fabric Structure for Coal Fired Energy Plant Processing Remediation

Basin Electric Power Coop

The Rundown

This bottom ash dewatering facility was designed, manufactured and installed by Legacy crews – including doors, LED lighting and ventilation. Crews installed the building over existing equipment. Eave extensions and a powered ventilation system provide six air turns per hour.

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.”
