About this opportunity
The Department of the Army Corps of Engineers Engineering District Omaha is soliciting proposals for the construction of six new pre-engineered metal Environmental Protection Shelters (EPS) at Ellsworth Air Force Base in South Dakota. Each shelter will be approximately 20,000 square feet and designed to accommodate B-2A "Spirit" aircraft while providing space for general aircraft maintenance. The project scope also includes associated airfield and ground support equipment paving, three maintenance kiosks of approximately 160 square feet each with electrical and communication infrastructure, construction compliant with AFI 16-1404 requirements, and partial demolition and reconstruction work on Dock 83. The solicitation has undergone five amendments since its initial posting on February 13, 2026, with the most recent amendment on April 20, 2026 revising specifications and drawings. The final proposal submission deadline is May 15, 2026, at 2:00 PM CDT, and prospective contractors should note that a site visit was scheduled for March 18, 2026, with a roster provided in the solicitation documents.
This is a standard commercial and institutional building construction contract with no set-aside designation, meaning all eligible contractors may compete for the award. The solicitation does not reference any incumbent contractors or specific award values in the provided documentation. The project represents a significant infrastructure development effort at Ellsworth AFB with multiple interconnected components requiring coordination among design, demolition, and construction activities. The place of performance is Ellsworth Air Force Base, South Dakota, and contractors should be prepared to manage compliance with military construction standards and airfield operational requirements throughout the project duration. Prospective bidders are advised to review all five amendments carefully, as they contain critical revisions to specifications, drawings, and contract clauses that supersede earlier versions.
