The U.S. Army Corps of Engineers is issuing a draft solicitation for the design and construction of a 50,000 sq ft testing facility at Hill Air Force Base in Utah, with total program funding of $111,500,000. The project supports the Sentinel program by housing advanced radiation testing equipment, including the ARES simulator and a neutron generator, within a reinforced structure with specialized shielding. The acquisition uses a two-step competitive process: interested parties first submit a Statement of Qualifications, with up to three down-selected to pitch for the award. The selected entity will receive a Firm-Fixed-Price agreement for Progressive Design-Build, covering design, preconstruction, and construction phases. Performance requires a Cybersecurity Maturity Model Certification Level 1 (Self-Assessment) for handling Federal Contract Information.
