Awarded by the US Army Corps of Engineers (USACE) Omaha District, the contract will support the construction of a single-bay fuel system maintenance dock at Ellsworth Air Force Base in Rapid City, South Dakota.

The project includes a new 39,000 sq ft (3,623 sq m) fuels maintenance facility, a single aircraft measurement bay and all associated back shop, administrative and facility support services. Its scheduled completion date is October 2026.

It is the third award for Conti Federal at the base. The company is also building a radio frequency (RF) hangar under a separate $70.5 million contract, and a B-21 weapon loader training facility for a further $43.9 million.

Ryan Kanzleiter, Conti Federal vice president of business development for the United States, said, “We’re looking forward to partnering with USACE Omaha on another B-21 project along with supporting the Rapid Disaster Infrastructure team at USACE Omaha. Together, our teams will focus on the mission and project delivery in supporting our nation’s defence infrastructure.”
