This project will include a space or spaces constructed to secure area standard Intelligence Community Directive/Intelligence Community Standard 705 (ICD/ICS 705).

“This award is a significant win for the Conti Federal team, as this will be our first project at Ellsworth Air Force Base. It is a great opportunity for us to grow our relationships with local partners and the USACE Omaha District,” said Conti Federal’s Program Director, Ryan Kanzleiter. “We are very excited to begin work on the RF Hangar and to tap into our local team located out of our Rapid City office. This project will position Conti Federal well for future projects at Ellsworth Air Force Base and in the USACE Omaha Area of Responsibility.”

Work is estimated to be completed by September 2025.

Conti Federal is currently constructing a helicopter facility at F.E. Warren Air Force Base in Cheyenne, Wyoming, as well as an F-35 Fighter Alert Shelter at Truax Field in Madison, Wisconsin, some of the many partnership opportunities Conti Federal has secured with the USACE Omaha District.
