About the company
SEH Design / Build, Inc. operates exclusively as a subcontractor on Department of the Air Force facilities support and management services, with all six recent awards flowing through Consolidated Nuclear Security, LLC on the Y-12 National Security Complex and Pantex Plant management and operating contract. The vendor has not held prime federal contract awards in the source data window and competes only in subcontract positions.
SEH Design / Build is a for-profit corporate entity headquartered in St. Paul, Minnesota. The source carries no SBA designations, set-aside certifications, or ownership descriptors; the vendor operates in full-and-open competitive posture as a sub to prime contractors. All six awards in the source data carry the same prime contractor (Consolidated Nuclear Security, LLC) and the same ultimate customer (Department of the Air Force Air Education and Training Command), indicating concentrated engagement on a single major program. Work is categorized uniformly under NAICS Facilities Support Services.
The vendor's recent activity shows steady shallow growth: one award in 2023, three in 2024, and two in 2025, with a combined potential value of $9.2 million across the portfolio. All six awards are incremental funding actions or task issuances dated between December 2023 and February 2025, suggesting continuous engagement on ongoing Pantex and Y-12 operations but no new program wins outside the Consolidated Nuclear Security prime relationship. The concentration of activity — one customer agency, one prime, one NAICS code — reflects a narrow operational footprint focused on facilities management and support services at Department of Energy weapons-production complexes managed through the Consolidated Nuclear Security contract. The vendor has not disclosed multi-year growth trajectory, teaming partners, or expansion into other agencies or programs within the source data.
