AI Contract Overview
The U.S. Army Corps of Engineers is pursuing the construction of Over the Horizon Radar (OTHR) infrastructure in Oregon using a Construction Manager at Risk approach under 10 USC 2808a Other Transaction authority. The project involves two remote, interdependent sites—transmitting and receiving—approximately 125 miles apart, each requiring the clearing and grading of over two square miles for large antenna arrays. Each site includes a range of permanent facilities: operations buildings, water treatment structures, vehicle maintenance and storage shelters, power areas with transformers and dual generator systems, fueling stations, security buildings, and a substation for electrical distribution. Both locations require septic systems, potable and fire water storage tanks connected to existing wells, and specialized infrastructure such as EMI shielding, fluid cooling units, and secured communications. A helicopter landing area and full utility connections are also required, with all construction to be performed in an isolated, logistically complex environment. The acquisition is structured as a two-step competitive process beginning with white papers to narrow the field to no more than three firms, followed by pitch meetings to select a single Construction Agent. The selected firm will receive a Firm-Fixed-Price agreement covering both preconstruction services and the ultimate construction phase, with milestones priced as design progresses and funding becomes available. Emphasis will be placed on demonstrated experience in heavy civil construction in remote areas, including establishing and operating man camps, managing tight schedules, and coordinating complex logistics. Preference will be given to those with prior experience involving radar systems, OTHR projects, or working in partnership with Tribal entities. The solicitation is open for white paper submissions through August 12, 2026, and is being managed by the USACE Kansas City District with primary contact through Michael France.

Acquisition Strategy (Pre-Award)
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 Construction Agent for award of the initial preconstruction services with a modification for construction award.
Award
The agreement will be awarded to the most qualified Construction Agent to provide preconstruction services and construction. Post-award Phase 1 of the CM@R includes Pre-construction services and Post-award Phase 2 includes the construction. The agreement will be Firm-Fixed-Price (FFP). The FFP for construction milestones will be agreed to as the design is finalized and funds are available.
Key Qualifications that will be used for the
Demonstrated experience with heavy civil construction in remote locations. (Experience specific to radar arrays, other OTHR systems, and work with Tribal observers will be given more consideration)
Demonstrated experience in remote locations requiring establishing and maintaining man camps.
Demonstrated experience with work in remote locations requiring a tight schedule.
Demonstrated experience with work in remote locations requiring heavy logistical coordination.
