Quick Summary

The U.S. Army Corps of Engineers (USACE), District Sacramento (SPK), is issuing a special notice for an upcoming Progressive Design-Build (PDB) competition under Other Transaction Authority (OTA) for the Little Mountain Testing Facility (LMTF) project at Hill Air Force Base (HAFB), Utah. This project involves constructing a 50,000 sq ft facility to expand testing capabilities for the Sentinel program. An Industry Day is scheduled for May 14, 2026, and interested parties must sign up by May 11, 2026.

Project Overview

The LMTF project aims to construct a 50,000 sq ft facility at HAFB, UT, critical for meeting future Nuclear Hardness mission requirements in support of the Sentinel program. The facility will house expanded testing capabilities, including a laboratory for specialized radiation effects equipment, test cells, and control rooms. It will also feature support areas for material storage, dosimetry testing, a classified conference room, and a receiving area with a loading dock. Construction will be robust, utilizing reinforced concrete, structural steel, and specialized shielding (concrete, earth barriers, and standoff distance) to contain radiation. Advanced testing equipment, such as the Advanced Radiation Environment Simulator (ARES) and a 14 MeV neutron generator, will be housed within the facility for dose rate and total dose testing. The total program funding is $111,500,000.00.

Acquisition Strategy

USACE will employ a streamlined competitive selection process using Progressive Design-Build.

  • Step 1 – White Papers: Interested parties will submit a Statement of Qualifications (maximum 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 the award of initial design and preconstruction services, with a modification for design completion and construction award.

Contract Details

The agreement will be awarded to the most qualified progressive design-build entity (PDBE). The contract type will be Firm-Fixed-Price (FFP) for successive design and construction milestones, agreed upon as the design progresses and funds become available.

  • Phase 1: Design and Pre-construction services.
  • Phase 2: Final design and construction. The NAICS Code is 236210 – Industrial Building Construction.

Key Requirements

This project requires a Cybersecurity Maturity Model Certification (CMMC) Status of Level 1 (Self-Assessment). Performance will involve handling Federal Contract Information (FCI). Interested parties must have achieved Final Level 1 (Self-Assessment) Status and affirm completion of the required self-assessment and attestation at the time of award.

Key Dates & Events
