About Hill International, Inc.

Written by GovTribe AI ·

Hill International, Inc.'s Washington DC Division, a subsidiary of Global Infrastructure Solutions Inc., provides construction management, project management, and engineering consulting services to federal agencies as a prime contractor across full-and-open and multiple-award federal vehicles, with no SBA set-aside designations in its recent footprint.

The Washington DC Division operates as a pure prime (100% of 223 awards in the portfolio), competing across GSA schedules and agency-specific indefinite delivery vehicles without set-aside status. Hill International is a for-profit entity structured as a corporate subsidiary; the parent, Global Infrastructure Solutions Inc., is headquartered in Newport Beach, California. The division's capability portfolio centers on construction management as agent (CMA) services, construction quality management (CQM), commissioning advisory, and project management support for federal facilities modernization, infrastructure renovation, and courthouse and office building upgrades. Representative recent work includes a $2.75 million firm fixed-price delivery order from GSA Region 5 (May 2024) for construction management and commissioning on the Carl B. Stokes United States Courthouse Plaza Replacement Project in Cleveland, Ohio, running through May 2027; a $1.62 million BPA call from the Centers for Medicare and Medicaid Services (June 2023) for construction manager as agent services on the CMS Headquarters Back on Campus Project in Woodlawn, Maryland, through December 2026; and a $914,895 BPA call from the Social Security Administration (September 2022) for construction management as agent on the Robert M. Ball stair tower and fire protection project in Woodlawn, Maryland, through July 2025. A $1.22 million definitive contract from CMS (April 2026) for California services and supplemental work on roof renovation and elevator modernization at CMS Headquarters runs to December 2028.

Customer concentration reflects strong positioning with facility-owner agencies. The top five customer agencies by award count (GSA Public Buildings Service, Department of the Army, Department of State Bureau of Overseas Building Operations, Smithsonian Institution, and GSA National Capital Region) account for 49% of awards. By potential dollar value, the ranking shifts materially: GSA Federal Acquisition Service dominates with 2 awards carrying $255.9 million combined potential value (63% of the portfolio's total), anchored by Hill International's $200 million Federal Supply Schedule contract (renewed January 2024 through January 2029) and a $60 million single-award Blanket Purchase Agreement with the Federal Railroad Administration for Support, Technical, Oversight, Review, and Monitoring (STORM) services, awarded September 2024 through September 2029. GSA National Capital Region, NASA Headquarters, GSA Region 2, and NASA Langley Research Center round out the top-five dollar customers. The Federal Supply Schedule contract spans 17 labor categories at hourly rates from $66.86 (administrative support) to $278.32 (project executive with 20 years' experience); no security-cleared positions are offered, reflecting the civilian-facilities focus.

Hill International's vehicle position centers on GSA schedules and agency IDIQs. The Multiple Award Schedule represents the largest activity footprint with 93 task orders valued at $217.8 million combined potential; the Professional Services Schedule carries 33 task orders at $33.1 million combined value. Army contracts DACA3193D0030 and DACA3195D0033 account for 14 and 12 task orders respectively. Recent awards show a declining trajectory: 6 awards in 2022, 3 in 2023, 4 in 2024, and 1 award each in 2025 and 2026. Seven awards with ultimate completion dates in the next twenty-four months carry combined potential value of $16.3 million, presenting modest recompete exposure within the near-term window.

Service Contract Inventory captures a subset of federal services activity: SCI-reported invoicing ran $4.7 million in FY2022, $4.6 million in FY2023, and $3.9 million in FY2024, with reported federal FTE delivery of 13.9, 11.9, and 11.1 FTEs in those years respectively. Government-paid hourly rates on SCI prime contracts median around $154.46 per hour, with the 90th percentile reaching $265.95 per hour. Across SCI-reportable prime contracts, subcontractor hours account for an average 3% share, with 24 named subcontractors appearing across the prime portfolio — indicating Hill International primarily builds and staffs its own delivery teams rather than operating as a labor broker. The division does not appear in SCI records as a subcontractor to other primes, reinforcing its pure-prime posture across the federal footprint.
