The Whiting-Turner Contracting Company

The Whiting-Turner Contracting Company (doing business as The Whiting-Turner Contracting Co), a large, for-profit construction management and general contracting firm headquartered in Towson, Maryland, delivers design-build, design-bid-build, renovation, repair, and new facility construction services to federal agencies as a prime contractor on 99% of its federal awards and competes under full-and-open, unrestricted procurement (no set-asides). The company operates across commercial and institutional building construction (NAICS 236220) and holds a federal prime footprint of 486 awards with combined potential value of $60.07 billion, making it one of the federal government's largest construction contractors.

Whiting-Turner's customer concentration is heavily weighted toward defense and civilian infrastructure modernization. The top five funding agencies account for a majority of awards, anchored by the Department of the Navy Naval Facilities Engineering Command (76 awards, $29.51 billion combined potential value), the Department of Homeland Security US Coast Guard (32 awards, $7.44 billion), the Department of Health and Human Services National Institutes of Health Construction (5 awards, $2.93 billion), the Department of the Navy (67 awards, $1.89 billion), and the Department of the Army Corps of Engineers Engineering District Baltimore (44 awards, $908 million). Together these five entities represent 71% of the vendor's combined potential value across all awards. Recent representative prime contracts include a $400 million accelerated design-build delivery order with the Coast Guard for barracks, training facility, galley, and firehouse at USCG Training Center Cape May, New Jersey (April 2026, currently suspended pending notification); a $255.9 million design-build delivery order with the US Census Bureau for renovation and consolidation of Census and Bureau of Labor Statistics facilities at the GSA Suitland Federal Center in Maryland (December 2022); a $213.5 million delivery order with Naval Facilities Engineering Command for three design-build facilities at Naval Air Weapons Station China Lake, California (September 2021); a $163.1 million definitive contract with Naval Facilities Engineering Command for Hurricane Florence recovery military construction at Marine Corps Air Station Cherry Point, North Carolina (August 2025); and a $138.2 million delivery order with the Coast Guard for CERCLA cleanup and waterfront recapitalization at Base Seattle supporting homeporting of new USCG Polar Security Cutters (August 2025).

Whiting-Turner's position across parent vehicles is extensive and spans multiple large construction IDIQs. The vendor holds seats on the $4 billion National Multiple Award Construction Contract III (NMACC III) with the U.S. Coast Guard (effective through September 2033), the $16 billion Unrestricted Design-Build/Design-Bid-Build Hawaii & Wake Island MACC with Naval Facilities Engineering Command (effective through June 2033), the $2 billion Southeast Area of Responsibility Multiple Award Construction Contract with Naval Facilities Engineering Command, the $1.999 billion Southeast region general construction IDC with Naval Facilities Engineering Command (effective through June 2030), the $1 billion NAVFAC Northwest MACC for Washington, Oregon, and Idaho (effective through September 2031), the $950 million Hampton Roads Area of Responsibility Multiple Award Construction Contract with Naval Facilities Engineering Command, the $495 million Design-Build and Design-Bid-Build Construction Services Hawaii IDIQ with Engineering District Honolulu (effective through May 2030), the $245 million South Alabama Region MATOC with the US Army Corps of Engineers Mobile District, and the $50 million National Gallery of Art Small and Medium Construction Projects IDIQ (effective through October 2029). Whiting-Turner also recently received a $10 billion multiple-award design-build construction IDIQ from US Customs and Border Protection (May 2026) for CBP facilities nationwide, and a $29.55 million Other Transaction IDV from Naval Sea Systems Command (August 2025) for procurement and supply of TATB-based energetic materials.

Activity has remained relatively steady year over year, with awards ranging from 13 in 2022 to 23 in 2025. However, 31 awards (combined potential value $1.42 billion) face ultimate completion inside the next twenty-four months and therefore carry recompete risk. SCI-reported invoicing across federal service contracts captured above the $150,000 threshold totaled $260.4 million in FY2022, $249.7 million in FY2023, and $269.8 million in FY2024 — a relatively flat profile that understates the vendor's construction delivery model, which emphasizes subcontracted labor. Across SCI-reportable prime contracts, 63% of contractor hours are performed by subcontractors, with 368 named subcontractors reported in the dataset. Government-paid hourly rates on federal services contracts run a wide spectrum, from a 10th percentile of $93.68 per hour to a median of $557.44 per hour to a 90th percentile of $5,090.05 per hour, reflecting the diversity of skill and specialization across Whiting-Turner's service delivery model. FTE trajectories show a sharp increase from roughly zero FTEs in FY2022–FY2023 to 184 FTEs in FY2024, indicating expanded staffing or SCI reporting visibility in that year.

Whiting-Turner operates predominantly as a prime contractor and does not pursue federal work as a subcontractor at scale; the sub-award footprint consists of four named sub awards to Aerospace Corporation, GE Energy Power Conversion Naval Systems Inc., Honeywell Federal Manufacturing & Technologies LLC, and Aerospace Corporation, involving engineering services, transformer oil sampling, and facility management operations reimbursable funding. The company's service delivery model leans heavily on a broad subcontractor base rather than organic vertical integration, which is consistent with large construction management firms that coordinate specialized trades and subcontractors rather than perform all labor in-house. All visible federal awards are unrestricted and full-and-open competed; the vendor has no SBA set-aside posture and consistently competes as a large business across its federal portfolio.
