Seres-Arcadis SB JV, LLC

Seres-Arcadis SB JV, LLC, the Joint Venture Division of Seres Engineering & Services LLC, is a minority-owned, Asian-Pacific American-owned small disadvantaged business delivering environmental remediation, site assessment, munitions response, and natural resources management services to Army Corps of Engineers districts as a prime contractor under USACE multiple-award IDIQs. The joint venture competes full-and-open (no set-aside designations on recent awards) and is headquartered in Charleston, South Carolina.

The vendor's entire prime footprint serves Army Corps of Engineers environmental programs. The Department of the Army Corps of Engineers Engineering Support Center Huntsville leads by potential value (8 awards, $404.7 million combined), while the Army Corps of Engineers Engineering District Baltimore leads by award count (22 awards, $301 million combined). The remaining three customers (Army Corps of Engineers Engineering District New York, Engineering District Jacksonville, and Army Installation Management Command Southwest Region) account for less than 1% of the portfolio by value. Seres-Arcadis SB JV sits on three USACE parent vehicles: the USACE Multiple Award Environmental Services 2017 (MAES 2017) with 12 task orders ($48.9 million), the Multiple Environmental Government Acquisition - Small Business Military Munitions Response Program with 9 task orders ($7.8 million), and Indefinite Delivery Contract W912DR18D0008 with 8 task orders ($4.4 million).

Representative recent work includes a $2.138 million firm fixed-price delivery order (August 2025) to decommission groundwater recirculation systems at the OASIS Point Fuel Site, Fort Drum, New York, under MAES 2017; a $1.375 million Total Small Business delivery order (July 2024) for time-critical PFAS removal actions at Fort Gregg-Adams, Virginia; a $1.081 million Total Small Business delivery order (September 2024) for Installation Natural Resources Management Plan survey support; and a $7.49 million delivery order (September 2022) for Phase I remedial investigation services at Pittsburgh Air Reserve Station and Pittsburgh Air National Guard Base, with subcontracted drilling services from HD Sonic Drilling (woman-owned small business) and Parratt-Wolff, Inc. (small disadvantaged business).

The vendor's capability footprint centers on remediation services (24 awards in the source) and engineering services (9 awards), with PSC concentration in Architect and Engineering—General (14 awards) and Environmental Systems Protection / Environmental Remediation (10 and 9 awards respectively). Activity has been episodic — 11 awards in 2020, then three in 2021, six in 2022, three in 2024, and one in 2025 — suggesting recent recompete activity and potential recompete cliff exposure. Eight awards (combined potential value $15.6 million) face ultimate completion within the next twenty-four months. The parent company, Seres Engineering & Services LLC, carries the same minority and small disadvantaged business certifications and is also based in Charleston, South Carolina.
