Potomac-Hudson Engineering Inc.

Potomac-Hudson Engineering Inc., a for-profit environmental consulting firm based in Rockville, Maryland, operates as a prime contractor (99% of recent awards) delivering environmental assessments, National Environmental Policy Act (NEPA) documentation, and specialized environmental compliance services to federal agencies under full-and-open competition and total small business set-asides. The company competes predominantly under small business set-asides — across the award footprint, roughly one-third of named customers are pursued on total small business grounds — with GSA Multiple Award Schedule and Professional Services Schedule vehicles anchoring most of its delivery-order work.

Potomac-Hudson's customer concentration is broad but defense-heavy. The top five customer agencies by award count account for 33% of recent awards and include the Department of the Navy (33 awards, $7.5 million combined potential value), United States Marine Corps (29 awards, $6.3 million), and Department of Veterans Affairs Headquarters (28 awards, $2.9 million). However, the potential-value ranking diverges sharply: the Department of Energy National Nuclear Security Administration anchors $97.4 million across four awards, the Department of Homeland Security U.S. Coast Guard holds $61.9 million across 16 awards, and GSA Federal Acquisition Service accounts for $56.3 million across eight awards. These three customers alone represent 48% of combined potential value, signaling that Potomac-Hudson's highest-dollar work concentrates in energy, maritime, and federal real property domains rather than in the volume-heavy Navy and Marine Corps contracts.

The company's capability portfolio centers on environmental site assessments, environmental impact statements, NEPA compliance documentation, water quality monitoring, and hazardous-materials inspections. Representative prime work includes a $108 million single-award Blanket Purchase Agreement with the Department of Energy Office of General Counsel running through September 2027 for specialized environmental consulting and NEPA analysis across DOE programs; a $26.5 million BPA call order from DOE for technical support services and NEPA activities (with an administrative modification in August 2024 reflecting organizational changes); a $12.6 million call order from DOE's Office of Electricity for NEPA support services; a $837 thousand delivery order from GSA Region 9 for an environmental impact study of the Nogales-DeConcini Land Port of Entry in Arizona (total small business set-aside); a $753 thousand delivery order for an environmental impact study of the Douglas, Arizona Land Port of Entry; and a $688 thousand delivery order for environmental assessment and Phase II environmental testing at the new U.S. Courthouse in Chattanooga, Tennessee. Work on the International Joint Commission side includes multiple small-to-mid-sized delivery orders on Great Lakes water quality, ecosystem services valuation, microplastics monitoring frameworks, climate resilience, and manure management.

Potomac-Hudson places task orders under two dominant parent vehicles: the GSA Professional Services Schedule (214 task orders, $107.3 million combined potential value) and the GSA Multiple Award Schedule (35 task orders, $154.8 million combined potential value). The company also holds an Indefinite Delivery Contract (N6247703D0152) with the Navy and a $250 thousand Indefinite Delivery Contract with the United States Mint for environmental assessments of Mint facilities.

Activity has contracted from a historical pace: Potomac-Hudson averaged 12.5 awards per year in 2022–2023, declining to nine awards in 2024 and seven in 2025, with three awards placed year-to-date in 2026. Fifteen awards (combined potential value $41.9 million) reach ultimate completion within the next twenty-four months and face recompete exposure. SCI-reported federal service-contract invoicing reached $892 thousand in FY2024 (2.8 FTEs), up from $280 thousand in FY2023 (1.9 FTEs), representing a small slice of the company's total federal revenue. On SCI prime contracts, government-paid rates ranged from a median of roughly $149.79 per hour to a 90th percentile of $205.70 per hour, with the company's GSA labor portfolio spanning entry-level clerical roles at $42.58 per hour through senior program management at $181.87 per hour across 33 unique labor categories, all non-cleared positions with educational requirements from high school through bachelor's degree.

Potomac-Hudson operates primarily as a prime (99% of awards) and brings minimal subcontractor engagement — across SCI-reportable contracts, subs accounted for 11% of total hours, with four named subcontractors appearing across the prime footprint. The company maintains three named joint-venture subsidiary structures (Phe-Baker JV, Phe-Baker JV2, Phe-Baker JV3, and Phe-Ndn JV, all LLCs), which may function as vehicles for specific customer or geographic commitments but do not appear to anchor separate capability lines in the recent award record. Recent sub work includes engineering services on an Amentum Technology construction-management contract for the International Falls Land Port of Entry project and pollution-prevention planning support under a Trevet-Noreas JV prime at Marine Corps Air Station Camp Pendleton.
