About this opportunity
The Department of the Army Corps of Engineers Engineering District Omaha is seeking proposals for the construction of a new B-21 Flight Simulator Facility addition at Ellsworth Air Force Base in South Dakota. This project will expand the existing flight simulator facility to support B-21 mission requirements and falls under the Commercial and Institutional Building Construction category (NAICS 236220). The solicitation has undergone multiple amendments since its initial posting on October 17, 2025, with updates to specifications, drawings, wage determinations, and project requirements. The proposal due date has been extended several times, with the current deadline set for February 12, 2026, at 1400 Central Time. While the notice does not specify evaluation criteria details, contractors should prepare comprehensive proposals addressing all updated specifications and drawings included in the nine amendments issued to date.
This solicitation carries no set-aside designation and is open to all eligible contractors. The notice does not identify any incumbent contractors or provide specific award value or budget information. The place of performance is Ellsworth Air Force Base, located at 57706 in South Dakota, where the new facility will be constructed. The multiple amendments—particularly those addressing wage determinations, drawings, and specifications—indicate that this is a complex, federally-funded construction project subject to prevailing wage requirements. Contractors should review all amendments thoroughly, particularly the most recent updates to specifications dated December 5, 2025, and wage determination revisions to ensure compliance with all current contract requirements.
