Clark Nexsen Inc.

Clark Nexsen Inc. NA Division, doing business as Clark Nexsen Owen Barbieri & Gibson PC, is a full-service architectural and engineering firm that serves as a prime contractor delivering facility design, engineering, infrastructure assessment, and construction-related services to federal agencies across civilian and defense portfolios. The firm operates as a subsidiary of Johnson, Mirmiran & Thompson, Inc., and competes entirely in full-and-open federal procurement with no set-aside designations across its recent award footprint.

Clark Nexsen's customer base splits sharply between defense and civilian infrastructure customers. The Department of Homeland Security's U.S. Coast Guard anchors the largest potential-value share (70 awards, $357.2 million combined potential value) across nationwide architectural and engineering services work, including airfield pavement inspections, structural analyses, facility design, and station renovations. The Department of the Navy Naval Facilities Engineering Command represents the second-largest customer by dollars ($219.4 million across 126 awards) and funds a broad portfolio of military construction, maintenance facility design, and specialized project delivery including aircraft hangar improvements, training facility modernization, and utilities infrastructure work. The Department of the Army Corps of Engineers (Norfolk and Savannah engineering districts combined) accounts for $118.1 million across 104 awards. The Department of Transportation Federal Highway Administration contributes $44.2 million across 97 awards, primarily bridge and culvert inspection services at national parks and federally owned structures. Collectively, these five customer agencies account for 77 percent of combined potential value across the firm's 1,419 total awards. The firm also maintains active relationships with the Department of Agriculture's Animal and Plant Health Inspection Service, holding a $15 million Indefinite Delivery Contract for nationwide architect-engineer services supporting facility upgrades, biosafety operations, and agricultural research infrastructure.

Clark Nexsen places significant task-order volume under five named parent indefinite delivery contracts. The Coast Guard Nationwide Architectural and Engineering Services 2017-2022 vehicle anchors 53 task orders carrying $12 million in combined potential value. Army Corps of Engineers IDCs (W9123607D0012 and N4008519D9041 combined) support 113 task orders valued at $113.8 million. Navy NAVFAC contracts (N4008010D0303) support 97 task orders at $30.2 million. The Federal Highway Administration Bridge Inspection Services IDC (DTFH7117D00002) carries 43 task orders at $5.5 million. Work is performed from multiple locations including Virginia Beach, Seattle, Ashburn, Cleveland, and Cockeysville (the parent company's Maryland headquarters), with performance scope spanning domestic installations, national parks, military bases, and research facilities nationwide.

Representative recent delivery orders demonstrate Clark Nexsen's scope across both major customers. A $3.97 million Coast Guard award (April 2026) covers owner's representation services for the rebuild of Coast Guard Station South Padre Island under the Nationwide A&E Services parent vehicle. A $9.4 million USDA APHIS delivery order (September 2025) funds biosafety, select agent training, and containment operations and training programs at Manhattan, Kansas. A $7.5 million Navy Naval Facilities Engineering Command order (August 2023) covered preparation of solicitation documents for FDA services supporting the P-222 Project. A $8.05 million Navy NAVFAC award (February 2022) funded Low Altitude Air Defense Missile Maintenance and Operations Facility planning and design at Marine Corps Air Station Cherry Point. Smaller recurring work includes bridge inspections across Federal Highway Administration contracts ranging from $31,000 to $272,000 per task order, and Coast Guard airfield pavement inspections valued between $152,000 and $794,000.

Activity has declined materially in recent years: 25 prime awards in 2022, declining to 4 in 2024 and 7 in 2025, with 2 awards recorded through April 2026. Ten awards (combined potential value $21.7 million) face ultimate completion within the next twenty-four months and therefore expose the firm to recompete risk. The firm's primary NAICS profile centers on engineering services (682 awards) and architectural services (150 awards), with service-contract-inventory reporting showing minimal SCI-captured activity — $2.6 million invoiced across three fiscal years (FY2022–FY2024) representing roughly 10 FTE equivalents. SCI-reported government-paid rates on prime contracts median around $130/hr, with a 90th percentile reaching $17,576/hr reflecting high-value professional engineering labor. Across SCI-reportable prime contracts, subcontractors performed roughly 27 percent of total contractor hours, with six named subs identified; the firm operates predominantly as a prime builder of its own delivery teams rather than as a subcontractor or sub-heavy prime.
