About Solterra Engineering Inc.
Solterra Engineering Inc., a Wyoming-based Subchapter S corporation, operates exclusively as a subcontractor in federal transportation infrastructure work, with all four recent awards routed through a single prime contractor on Federal Highway Administration projects. The vendor has generated $515 thousand in combined obligated dollars across two years of activity (2022–2023), with no prime contract footprint and no federal grant activity.
Solterra's entire customer concentration is the Department of Transportation Federal Highway Administration, which accounts for 100% of recent awards. All four sub-awards flow through Oftedal Construction, Inc. as the prime contractor on highway and bridge construction work. The projects are testing and construction-management definitization tasks on National Park Service infrastructure: Yellowstone National Park Northeast work (two sub-awards in August 2022) and Grand Teton National Park's Moose Wilson Road Phase 1 supplemental testing (two sub-awards in October 2023). The vendor operates under a single parent IDC (69056719D000003).
Activity has flatlined at two awards per year across the two-year window. The most recent award is nearly three years old, indicating no new federal fundings since October 2023. The vendor's work is categorized under NAICS 2371 (Highway, Street, and Bridge Construction). Given the sub-only posture, reliance on a single prime, single customer agency, and single parent vehicle, Solterra has minimal federal market mobility and no internal federal business development infrastructure visible in the award record.
