Little Mountain Testing Facility Progressive Design-Build Project

For Progressive Design-Build (PDB) under Other Transaction (OT) Project: Little Mountain Testing Facility (LMTF), Hill Air Force Base (HAFB), Utah (UT) The U.S. Army Corps of Engineers (USACE) is issuing this DRAFT program solicitation for the design and construction of the LMTF using Progressive Design-Build under 10 USC §2808a Other Transaction for Construction. This notice is provided for informational purposes to allow interested parties to review the proposed acquisition approach and provide feedback prior to release of the official solicitation. Project Overview Project Title: LMTF Location: HAFB, UT Agency: USACE, District Sacramento (SPK) NAICS Code: 236210 – Industrial Building Construction Total Program Funding: $111,500,000.00 Project The primary goal is to construct a 50,000 sq ft facility to house expanded testing capabilities in support of the Sentinel program at the Little Mountain Testing Facility. The facility is critical for meeting future Nuclear Hardness mission

requirements. Key components of the construction include: A laboratory for specialized radiation effects equipment, test cells, and control rooms. Support areas for material storage, dosimetry testing, and a classified conference room. A receiving area with a loading dock to accommodate forklifts and delivery trucks. Robust construction featuring reinforced concrete, structural steel, and specialized shielding (concrete, earth barriers, and standoff distance) to contain radiation. The new facility will house advanced testing equipment, including the Advanced Radiation Environment Simulator (ARES) and a 14 MeV neutron generator, to provide dose rate and total dose testing for parts, modules, and entire systems. Acquisition Strategy The USACE will use a streamlined competitive selection process: Step 1 –White Papers: Interested parties will submit a Statement of Qualifications {max 10 pages}. The government intends to down-select up to three Companies to proceed to Step 2. Step 2 – Pitches: Selected Companies will participate in pitch meetings. One company will be selected as the Design-Build team for award of the initial design and preconstruction services with a modification for design completion and construction award. Award The agreement will be awarded to the most qualified progressive design-build entity (PDBE) to provide design development, preconstruction services, and construction. Post-award Phase 1 of PDB includes Design and Pre-construction services and Post-award Phase 2 includes the final design and construction. The agreement will be Firm-Fixed-Price (FFP). The FFP for successive design and construction milestones will be agreed to as the design progresses and funds are available. Key Security

Requirements General Requirement and Authority Required Level: The Government has determined that this project requires a Cybersecurity Maturity Model Certification (CMMC) Status of Level 1 (Self-Assessment). Performance under the resulting Agreement will require the handling of Federal Contract Information (FCI). Interested parties must have achieved a Final Level 1 (Self-Assessment) Status and, at the time of award, affirm completion of the required self-assessment and attestation.
