Potomac-Hudson Engineering Inc.

Potomac-Hudson Engineering Inc., a small business environmental consulting firm based in Rockville, Maryland, operates as a prime contractor (99% of recent awards) delivering environmental assessments, NEPA documentation, environmental site assessments, water quality monitoring, and hazardous-materials inspections across 60 federal agencies. The company competes predominantly under total small business set-asides on GSA Multiple Award Schedule and Professional Services Schedule vehicles, with recent prime activity spanning environmental consulting, engineering, and architectural services.

Potomac-Hudson's customer concentration is dispersed across defense and civilian agencies. The top five customers by award count—the Department of the Navy (33 awards, $7.5 million combined potential value), the United States Marine Corps (29 awards, $6.3 million), the Department of Veterans Affairs Headquarters (28 awards, $2.9 million), the Department of the Navy Naval Facilities Engineering Command (25 awards, $32.9 million), and the Veterans Integrated Service Network 5 (24 awards, $2.2 million)—account for 33% of awards. However, the top customers by potential value diverge significantly: the Department of Energy National Nuclear Security Administration (4 awards, $97.4 million combined potential value) anchors 15% of the total dollars, followed by the Department of Homeland Security U.S. Coast Guard (17 awards, $61.9 million), GSA Federal Acquisition Service (9 awards, $56.3 million), and the Department of the Army Installation Management Command (23 awards, $42.6 million). The dollar concentration reflects a few large BPAs and IDIQs against a broad base of smaller task orders and purchase orders.

Potomac-Hudson's vehicle portfolio centers on two dominant GSA platforms. The Professional Services Schedule accounts for 214 task orders and $107.3 million in combined potential value, primarily for asbestos inspections, soil and water sampling, and building assessments at federal facilities. The Multiple Award Schedule places 35 task orders (combined potential value $148.1 million) for environmental impact statements, NEPA compliance work, and water-quality studies—notably for the International Joint Commission on Great Lakes research, the U.S. Mint environmental assessments, and GSA regional offices conducting environmental reviews for land ports of entry and federal courthouses. Beyond GSA vehicles, Potomac-Hudson holds a $108 million single-award Blanket Purchase Agreement with the Department of Energy Office of General Counsel for NEPA support and environmental compliance documentation, with two recent BPA calls generating $12.6 million and $19.4 million in combined ceiling value. The company also holds a $50 million USDA Forest Service multiple-award BPA for Land Management Integrated Resources professional services (awarded August 2026, running through March 2033) and an OASIS+ Small Business multiple-award IDIQ with GSA (awarded September 2026, running through December 2034) carrying no task orders as of the award date.

Recent representative work includes a $1.73 million GSA Multiple Award Schedule delivery order (September 2022) for an environmental assessment of the Grand Portage and International Falls areas; a $753 thousand GSA Region 9 delivery order (November 2021, running through October 2025) for an environmental impact study of the Douglas, Arizona Land Port of Entry; a $688 thousand GSA Region 4 delivery order (March 2023, running through February 2027) for environmental assessments and Phase II environmental testing at the Chattanooga Federal Courthouse; a $302 thousand delivery order (January 2024, completed December 2024) for NEPA Environmental Impact Statement services at the Lynden and Sumas, Washington land ports of entry; a $219 thousand delivery order (September 2022, completed September 2024) from the International Joint Commission for community-of-practice development and climate-resilience planning tools for Great Lakes communities; and a $1.1 million GSA Region 9 delivery order (September 2025, running through December 2028) for an environmental impact study of the Nogales-DeConcini Land Port of Entry in Arizona.

Activity has declined moderately over the past five years—eight awards in 2023, nine in 2024, seven in 2025, five in 2026, and one in early 2027—suggesting either a shift in capture strategy toward larger vehicles or a recompete cycle. Eight awards with a combined potential value of $33.4 million reach ultimate completion within the next twenty-four months and therefore face recompete exposure.

Service Contract Inventory reporting shows minimal labor intensity. Across SCI-reportable prime contracts, Potomac-Hudson invoiced $2.1 million over FY2023–FY2025 ($280 thousand in FY2023, $892 thousand in FY2024, $973 thousand in FY2025) with between 1.8 and 2.8 FTEs per fiscal year. Government-paid hourly rates on SCI records ran a median of $149.79 per hour, with a 10th percentile of $0.00 per hour (likely a reporting lag in one early contract) and a 90th percentile of $205.70 per hour. On GSA Schedule, Potomac-Hudson carries 33 labor categories spanning Clerical Admin I at $42.58 per hour through Program/Project Manager IV at $181.87 per hour, with no security-cleared roles offered. The low SCI and GSA labor-rate volume is consistent with a delivery model centered on environmental assessments, impact statements, and documentation work rather than ongoing staffing support; the work is largely project-based and delivered by senior environmental scientists and engineers.

Potomac-Hudson operates as a self-performing prime across its SCI-reportable contracts, with an average sub-hours share of 6% and four named subcontractors reported across the dataset. In its rare subcontractor role, Potomac-Hudson performs construction management, commissioning, and engineering services under Amentum Technology on the International Falls Land Point of Entry project and pollution-prevention planning under Trevet-Noreas JV on Marine Corps Air Station Camp Pendleton. The corporate structure includes four named limited-liability-company joint ventures: Phe-Baker JV, Phe-Baker JV2, Phe-Baker JV3, and Phe-Ndn JV, likely vehicles for specific customer or project teaming arrangements.

NAICS concentration confirms the environmental-consulting posture: 292 awards under NAICS 541620 (Environmental Consulting Services), 31 under NAICS 541330 (Engineering Services), and 24 under NAICS 541310 (Architectural Services). The PSC framing mirrors this—140 awards under PSC Special Studies/Analysis–Environmental Assessments and 56 under Other Environmental Services—with the remaining volume spread across general support and architectural-engineering categories. The combined potential value of $646.8 million across 424 awards reflects a mature, diversified federal customer base anchored by large GSA vehicles, substantial DOE and DHS programs, and recurring defense-facility environmental compliance work, all priced at small business set-aside rates.
