Vanasse Hangen Brustlin Inc.

Vanasse Hangen Brustlin Inc. (VHB), a Williamsburg, Virginia-based engineering and environmental consulting subsidiary of parent Vanasse Hangen Brustlin, Inc., delivers contaminated site assessment, remediation design, environmental compliance, infrastructure engineering, and transportation planning services to federal land management and transportation agencies as a prime contractor on 99% of its awards, competing full-and-open with no set-aside designations.

VHB's portfolio concentrates heavily on National Park Service work. The top five customer agencies account for 82% of awards and 95% of combined potential value, led by the Department of the Interior National Park Service National Office (141 awards, $122.3 million), followed at distance by the Department of Transportation Federal Highway Administration (15 awards, $70.8 million). The National Park Service Southeast and Northeast regional offices add another 47 awards worth $6.5 million combined. Within the NPS footprint, VHB executes delivery orders for Title III construction administration, schematic and design-development services, CERCLA technical support, preliminary assessments, remedial investigations and feasibility studies, and facility rehabilitation—typical work spanning national monuments, historical parks, and park units nationwide. Representative recent prime awards include a $2.8 million time-and-materials remedial investigation and feasibility study at Kennecott Mine and Mill in Wrangell-St. Elias National Park, Alaska (May 2023, ultimate completion April 2028); a $1.39 million transportation planning and traffic technician delivery order under the FHWA Transportation Planning IDIQ (April 2025, through September 2029); a $1.78 million Title III rehabilitation contract for the Lincoln Memorial Undercroft (December 2022); a $823 thousand program-of-requirements bridging document delivery for ferry embarkation relocation at Statue of Liberty National Monument (February 2022); and a $131 thousand delivery order for construction-phase engineering services at Vicksburg National Military Park (April 2026).

VHB holds two major indefinite delivery vehicles: a $60 million Transportation Planning IDIQ with the Federal Highway Administration (awarded October 2024, through April 2030, multiple award, no set-aside) covering transportation planning, pavement design, performance management, traffic monitoring, safety studies, asset management, environmental compliance, and engineering services, with two task orders placed to date; and a $46.6 million Blanket Purchase Agreement with the National Park Service against the GSA Multiple Award Schedule (awarded September 2021, through March 2027, multiple award, no set-aside) for contaminated site cleanup, environmental assessment, and remediation services under CERCLA, RCRA, and related authorities, exercised through frequent BPA calls—recent examples including a $410 thousand site-specific technical support call (April 2026, time-and-materials, through April 2029) and a $498 thousand technical and regulatory support call to the Environmental Compliance and Cleanup Branch (September 2025, labor-hours, through June 2026). Across the vendor award portfolio, the Multiple Award Schedule is the dominant parent vehicle (83 task orders, $75.8 million), followed by the NW IDIQ General Engineering Services contract 140P2021D0003 (90 task orders, $27.4 million).

Activity has decelerated over the past four years—from 41 awards in 2022 to 6 in 2025 and 2 in 2026 year-to-date—while combined potential value has declined from $220.6 million across the full portfolio. Within the next twenty-four months, 18 awards carrying combined potential value of $8.4 million face ultimate completion dates and therefore recompete exposure.

On SCI-reportable federal service contracts, VHB invoiced $15 million across FY2022–FY2024, with FY2024 reaching $7.7 million across 16.2 FTEs delivered. The trajectory shows growth: FY2022 invoicing of $2.5 million (3.3 FTEs) doubled to FY2023 at $4.7 million (2.4 FTEs contract-level, though the 7.3 FTE and 12.6 FTE activity-level figures suggest fuller utilization), then grew again in FY2024. Government-paid hourly rates on prime SCI contracts span a median of $188.95 per hour, with the 10th percentile at $112.19 per hour and the 90th percentile at $366.17 per hour. Across SCI-reportable prime contracts, subcontractors perform an average of 26% of contractor hours, with 16 named subcontractors engaged over the SCI period—a posture indicating VHB self-performs a substantial share of delivery but relies on subs for specialized or surge capacity work. VHB itself appears as a subcontractor only once in the source material, a $0 sub-award with WBK Engineering LLC on a community school demolition site assessment (July 2024), and as a sub-recipient on a $0 National Academy of Sciences grant subcontract on safe system concepts (April 2024).

The core capability framing across awards centers on CERCLA and RCRA site investigation, preliminary assessment, engineering evaluation, corrective action planning, and remedial design for federal properties; Title III construction-phase engineering; schematic design and design development for facility rehabilitation; transportation planning and pavement analysis; and environmental compliance documentation. VHB's primary NAICS concentration is Environmental Consulting Services (123 awards) and Engineering Services (115 awards), with PSC coding emphasizing Architect and Engineering General (87 awards) and Special Studies/Analysis Environmental Assessments (31 awards).
