B-21 Low-Observable Restoration Facility (Lo Hangar)

This project will be executed using a design-bid-build (DBB) project delivery method, which will require the contractor to provide the government with a complete facility and warranty based on the Request for Proposal (RFP). Construct a B-21 Low-Observable Restoration Facility (LO Hangar) at Ellsworth Air Force Base (EAFB), South Dakota (SD). This is one of the first major construction projects that serves as part of a multi-year facilities beddown in support of the B-21 program at EAFB, SD. This project will provide a new +/- 95,500 SF 2-bay hangar facility and associated airfield apron, site features, utilities, and infrastructure for maintenance of low observable characteristics of the emerging B-21 airframe. The project may also include bid options for furniture, furnishing and equipment (FF&E), intrusion detection systems (IDS), access control systems (ACS), and closed-circuit television (CCTV) systems.
