Clark Nexsen Inc.

Clark Nexsen Inc. NA Division, operating as Clark Nexsen Owen Barbieri & Gibson PC, is a full-service architectural and engineering firm based in Virginia Beach, Virginia, that competes as a prime contractor (100% of awards) on federal infrastructure and facility design projects without set-aside designations. The vendor is a subsidiary of Johnson, Mirmiran & Thompson, Inc., a Subchapter S corporation, and operates alongside Technicon Engineering, Inc. within the parent corporate structure.

Clark Nexsen's federal footprint centers on architectural, engineering, design, and construction-related services for civilian and defense agencies. The portfolio spans engineering services (685 awards), architectural services (150 awards), and specialized facility work across NAICS 541330 (Engineering Services) and 541310 (Architectural Services) classifications, with PSC coding emphasizing architect-engineer general services and design work. Representative prime awards illustrate the scope: a $10.1 million delivery order from the Department of Agriculture's Animal and Plant Health Inspection Service (Plains Area) for biosafety, select agent training, and containment operations and training programs at Manhattan, Kansas (September 2025); an $8.05 million Naval Facilities Engineering Command delivery order for P-2582D Low Altitude Air Defense Missile Maintenance and Operations Facility planning and design at Marine Corps Air Station Cherry Point, North Carolina (February 2022); and a $7.5 million Naval Facilities Engineering Command delivery order to prepare FDA services solicitation documents for the P-222 Project (August 2023). Recent work also includes a $3.97 million Coast Guard owner's representation delivery order for Station South Padre Island rebuild (April 2026), a $3.4 million Navy delivery order for architectural and engineering repair services at Naval Air Station Oceana's Student Housing Building 419 in Virginia Beach (August 2023), and a $3.08 million Navy delivery order for P-1499 POM24 PDA effort (November 2022). Bridge inspection and pavement assessment work for the Federal Highway Administration spans multiple delivery orders in the $100,000–$280,000 range across National Park Service structures and metropolitan airports.

Customer concentration sits heavily with defense and homeland security agencies. The top five customers by potential value account for 77% of combined potential value: the Department of Homeland Security US Coast Guard (71 awards, $357.7 million combined potential value), the Department of the Navy Naval Facilities Engineering Command (126 awards, $219.4 million), the Department of the Army Corps of Engineers Engineering District Norfolk (48 awards, $71.9 million), the Department of the Army Corps of Engineers Engineering District Savannah (56 awards, $46.2 million), and the Department of Transportation Federal Highway Administration (97 awards, $44.2 million). By award count, Navy programs dominate (382 awards, $10 million; 126 NAVFAC awards, $219.4 million), with significant Coast Guard exposure (71 awards, $357.7 million) reflecting Clark Nexsen's placement on the USCG Nationwide A&E Services 2017-2022 contract vehicle, which carries 53 task orders worth $12 million combined potential value.

Clark Nexsen places most of its delivery orders against Navy and Coast Guard indefinite delivery contracts. The top five parent vehicles are Navy IDC N4008010D0303 (97 task orders, $30.2 million), Army Corps of Engineers IDC W9123607D0012 (73 task orders, $36.7 million), Coast Guard HSCG8307D3WF171 (53 task orders, $12 million), Department of Transportation DTFH7117D00002 (43 task orders, $5.5 million), and Navy N4008519D9041 (40 task orders, $77.1 million). The vendor holds a $15 million Indefinite Delivery Contract with USDA Animal and Plant Health Inspection Service for nationwide architect-engineer services supporting facility upgrades and agricultural research infrastructure, which is referenced across multiple delivery orders.

Activity has declined sharply over the past five years — 25 awards in 2022 declining to 5 awards in 2026 (as of late September) — a trajectory suggesting maturation or portfolio rebalancing rather than growth. Seven awards (combined potential value $15.1 million) reach ultimate completion within the next twenty-four months and face recompete risk. The vendor carries obligated dollars of $404.7 million against combined potential value of $963.3 million (42% obligation rate), indicating room for drawdown on existing delivery orders.

Service Contract Inventory data, a partial view covering federal service contracts above the $150,000 threshold, shows Clark Nexsen invoiced $2.6 million across SCI-reportable prime contracts from FY2022 through FY2024, with FY2024 activity at $1.6 million across 4.0 FTEs. Government-paid hourly rates on prime SCI contracts run a median of $130.48 per hour, with senior labor pricing reaching the $17,576 per hour range. Across SCI-reportable prime contracts, subcontractors account for an average of 19% of total contractor hours, with six named subcontractors reported — suggesting Clark Nexsen builds most delivery team capacity in-house and uses subs for specialized or overflow work rather than relying on subcontractor-heavy models. The vendor operates as a pure prime on federal awards with no recorded sub-award participation, a posture consistent with its role as a specialized engineering and design firm competing directly for scope rather than feeding work to larger integrators.
