Hntb Corporation

HNTB Corporation, doing business as HNTB Arch, is an employee-owned, Kansas City-based architectural and engineering services firm competing as a prime contractor (95% of recent awards) on full-and-open federal procurements without set-aside designations. The vendor is a for-profit Subchapter S corporation and subsidiary of Hntb Holdings LTD, with a footprint of 743 federal awards spanning architecture, engineering, planning, and program management work across 39 customer agencies, generating $1.29 billion in combined potential value over the source period.

HNTB Arch's customer concentration is heavily weighted toward water infrastructure and military facility work. The Department of Transportation Federal Transit Administration leads by potential value at $720.4 million across 12 awards, anchored by a $670 million single-award indefinite-delivery contract for project management oversight services issued September 2024 and running through September 2029. The Department of the Army Corps of Engineers Engineering Support Center Huntsville contributes $158.4 million across 21 awards, while the USACE Engineering District Kansas City—HNTB's highest-frequency customer—places 158 awards valued at $89.5 million. Combined, the top five customer agencies account for 86% of potential value. Arlington National Cemetery Southern Expansion work dominates Army contract volume, with multiple phases spanning architectural design, construction services, testing, and facilities commissioning across Fort Myer, Virginia, valued at tens of millions cumulatively.

HNTB Arch holds three major indefinite-delivery vehicles anchoring its federal delivery model. The $670 million Federal Transit Administration 2024 Project Management Oversight Program contract (single award, September 2024 through 2029) funds programmatic oversight services to FTA's Office of Program Management in Washington, DC, with $13.57 million already obligated through September 2024 on a cost-plus-fixed-fee basis. A $15 million Army Headquarters IDC for Arlington National Cemetery Southern Expansion architectural and engineering design services was awarded December 2024 through July 2031, with task orders for design implementation, testing, and construction phase services. The $15 million USACE multiple-award IDC (August 2023 through August 2028) supports architectural and engineering services across the Mississippi Valley Division, with work including floodwall construction, levee safety, and flood risk management projects in Louisiana, Kansas, and Missouri. Top task-order vehicles by count include Indefinite Delivery Contract W912DQ08D0045 (69 task orders, $12.2 million), DACA4103D0010 (34 task orders, $3 million), and W912DQ14D1000 (25 task orders, $10.5 million).

Recent prime contract examples include a $7.875 million delivery order from the Department of Defense Engineering and Installation District Norfolk (August 2025) for Arlington National Cemetery Southern Expansion Phase II and III architect-engineer construction phase services through July 2029; a $10.2 million Army Corps of Engineers delivery order (September 2024) for the GIWW East Floodwall Tie-In design and engineering work in New Orleans through January 2028; a $13.57 million Federal Transit Administration delivery order (September 2024) for FTA project management oversight services through September 2029; a $1.934 million USACE delivery order (March 2025) for architectural and engineering services supporting Upper Turkey Creek Flood Risk Management in Kansas City through March 2030; and a $1.722 million USACE delivery order (April 2025) for the MRL Dumaine Street Floodwall Phase II project in New Orleans through August 2026. Work spans environmental assessment, groundwater monitoring, flood response planning, bridge design, wastewater studies, LEED certification, and software development for line-of-sight analysis of live fire training ranges.

Activity contracted sharply from 32 awards in 2023 to 22 in 2024 to 8 in 2025, with only one award recorded through March 2026 in the current source. Eleven awards with ultimate completion dates in the next twenty-four months carry $41.5 million in combined potential value, representing recompete exposure for HNTB and opportunity for competitors. HNTB operates predominantly as a prime and does not rely on subcontractors for federal work; across SCI-reportable prime contracts in FY2024, the vendor reported zero subcontractor hours, delivering services exclusively through its own labor. The vendor's subcontractor role is marginal—only five sub-awards appear in the source, all delivered to larger primes (CDM Federal Programs Corporation and ICF Incorporated) on transportation and environmental consulting tasks including traffic incident management, electric vehicle fire response strategies, and ecosystem restoration design for FHWA and other transportation agencies.

The vendor's SCI-reported federal service contract activity is minimal; only $213 thousand in invoiced revenue appears across three fiscal years (FY2022–FY2024), with 0.3 FTEs reported in FY2022 and FY2024 and zero in FY2023. This reflects SCI's narrow scope—contracts above $150,000—and does not represent the vendor's total federal services footprint, which is substantially larger based on the award portfolio. Government-paid hourly rates on SCI-reportable work ranged from $343/hr at the 10th percentile to a median of $351/hr, with outlier senior labor reaching $2,338/hr at the 90th percentile, indicating a mixed delivery model spanning junior engineering support and specialized senior expertise.
