About the company
Clark Construction Group LLC, a Bethesda, Maryland–based heavy civil and federal construction prime contractor, delivers large-scale design-build and design-bid-build construction services to the Department of Defense, Department of Homeland Security, and civilian federal agencies on a full-and-open (non-set-aside) basis, with 99% of recent awards as prime contractor and a combined potential value across all recent awards of $32.67 billion.
Clark Construction competes predominantly in Commercial and Institutional Building Construction (NAICS 236220) and Facilities Support Services, grounded in concrete delivery of military and federal facilities projects across military installations, border infrastructure, federal courthouses, and health-care systems. Recent representative prime work includes a $332 million design-build project at Laredo, Texas under the CBP Design-Build Construction IDIQ (awarded September 26, 2026, completion September 1, 2029); a $167.6 million firm fixed-price definitive contract for the Arlington National Cemetery Southern Expansion (awarded February 23, 2026, completion May 15, 2029); a $626.8 million design-build contract for the Veterans Affairs Health Care Center in El Paso, Texas (awarded December 19, 2023, completion February 29, 2028); and a $616.3 million contract for construction of the new CISA headquarters building at St. Elizabeths West Campus, Washington, DC (awarded August 16, 2024, completion April 16, 2029). The $616.3 million CISA project shows SCI-reported invoicing of $51.1 million across 71,765 contractor hours (34.5 FTEs) through fiscal year 2025, with blended government-paid hourly rates declining from $4,761.92/hr in FY2024 to $645.93/hr in FY2025 as the project transitioned from mobilization to production phases.
Customer concentration skews heavily toward maritime and defense infrastructure. The top five funding agencies account for 84% of combined potential value: the Department of Homeland Security Customs and Border Protection leads with 4 awards carrying $10.57 billion combined potential value; the Department of Navy Naval Facilities Engineering Command holds 9 awards worth $10.41 billion; the Department of the Army Corps of Engineers Engineering District Baltimore has 13 awards totaling $2.65 billion; the Department of Health and Human Services National Institutes of Health Construction carries 3 awards worth $2.55 billion; and the General Services Administration Public Buildings Service National Capital Region anchors 6 awards valued at $1.4 billion. By award count, the Department of the Navy dominates with 182 awards, followed by the Department of the Army with 44 awards, but the Customs and Border Protection and Navy rankings diverge significantly on dollar magnitude—CBP's four awards average $2.64 billion per task order, whereas Navy's 182 awards average $41.2 million.
Clark Construction holds four major indefinite delivery contracts. The CBP Design-Build Construction IDIQ (awarded May 4, 2026, ceiling $10 billion, completion May 10, 2031) is a multiple-award vehicle supporting border patrol stations, checkpoints, sector headquarters, and air facilities nationwide; Clark has received two delivery orders totaling $455.6 million in the past two weeks (the $332 million Laredo design-build awarded September 26, 2026, and a $123.6 million Laredo checkpoint facility awarded October 1, 2026). The Naval Facilities Engineering Command Large General Construction D.C., Maryland, and Virginia IDIQ (awarded June 25, 2026, ceiling $8 billion, completion June 24, 2034) is a multi-award vehicle; Clark's activity includes 37 task orders under an older NAVFAC indefinite delivery contract (N6247786C0109) and 20 task orders under another NAVFAC vehicle (N6247777C0172). The Army Corps of Engineers ENDIST Baltimore MATOC Design-Build Design-Bid-Build contract (awarded September 26, 2023, ceiling $499 million, completion September 24, 2028) carries 25 task orders worth $102.6 million combined. Clark also holds a single-award Naval Facilities Engineering Command Large General Construction contract (awarded September 19, 2023, ceiling $1.229 billion, completion September 18, 2028) supporting Washington D.C.–area military facilities.
Activity has accelerated recently. Annual award counts rose from 3 in 2025 to 9 in 2026 (through October), though the five-year trend shows overall volatility (9 awards in 2022, 7 in 2023, 4 in 2024). Ten awards carrying combined potential value of $1.89 billion reach ultimate completion within the next twenty-four months, representing significant recompete exposure across border infrastructure, cemetery expansion, and military facilities work. SCI-reported invoicing of federal service contracts above the $150,000 threshold totaled $1.07 billion across FY2022–FY2025, reflecting ramp-up: FY2024 peaked at $454.7 million across 441 FTEs and government-paid median hourly rates around $568.98/hr, with senior labor pricing reaching $3,644.34/hr and junior labor at $196.15/hr. FY2025 invoiced $295.6 million across 349 FTEs, indicating project-phase transitions and execution scaling.
Clark Construction operates as a general contractor with significant subcontracting depth. Across SCI-reportable prime contracts, subcontractors perform approximately 39% of total contractor hours, with 258 named subcontractors reported in the source. The $616.3 million CISA headquarters contract names 11 subcontractors for specialized trades: Calvert Masonry (concrete and masonry), Ruppert Landscape (landscaping), Otis Elevator Company (traction elevators), Pillar Construction (cold-formed metal framing), and teams performing utilities, drainage, membrane roofing, fire suppression, earthwork, electrical, and plumbing. The $927.6 million Federal Correctional Institution Leavenworth contract (awarded August 7, 2023, ceiling $927.6 million, completion September 11, 2026) shows 34 subcontractors performing 90% of contractor hours in FY2025, indicating prime-oversight delivery model with blended labor rates declining from $985.86/hr (FY2024) to $396.60/hr (FY2025) as execution scaled. The Smithsonian Museum Support Center Pod 6 contract ($111.8 million, awarded September 19, 2022, completion July 1, 2026) reported 22 subcontractors performing 81% of contractor hours in FY2025, with rates declining from $601.19/hr (FY2023) to $261.35/hr (FY2025).
Clark Construction LLC is the parent entity; Clark Construction Group LLC operates as the prime contracting subsidiary. The corporate structure includes 26 named subsidiaries spanning regional construction operations (Clark Construction Group - Texas, LP; Clark Design / Build Of California, Inc.), facilities management (Clark Facility Solutions LLC), specialty infrastructure (C3M Power Systems LLC; Edgemoor Infrastructure & Real Estate Of Washington DC LLC), and design-build platforms (Coda, LLC). Clark holds one named subcontract relationship: a GBSD Engineering and Manufacturing Development sub to Northrop Grumman Systems Corp (awarded September 16, 2025), indicating limited sub-to-prime volume relative to the 99% prime posture and suggesting Clark operates primarily as the general contractor rather than a feeder to larger primes on federal construction work.
