Summary

AI-generated · Aug 07, 2026

A Construction Manager at Risk (CM@R) is being sought to provide preconstruction services and construction for the Over the Horizon Radar (OTHR) Infrastructure in Oregon. The project comprises two interdependent sites—Transmitting and Receiving—about 125 miles apart that must be planned and built concurrently, with extensive facilities and utilities at both locations (operations, equipment/server rooms, water treatment, fuel storage, vehicle maintenance and storage, security, substation and switchgear, drive-through doors, EMI shielding, helicopter access, and utility systems), including government-furnished generators, a 14.4 kV load bank, and related networking and metering infrastructure.

Acquisition will be a streamlined, two-step competition: first, firms submit a 10-page Statement of Qualifications to be down-selected to up to three; second, selected firms present pitches, after which one Construction Agent will be chosen to perform preconstruction services and construction under a firm-fixed-price arrangement. Construction milestones will be defined as design advances and funds become available. Desired qualifications emphasize heavy civil construction experience in remote locations, particularly for radar/OTHR-related work and coordination with Tribal observers; capability to establish and maintain man camps and to meet tight, complex remote-site schedules.
