Geosyntec Jacobs A Joint Venture

Geosyntec Jacobs A Joint Venture, a joint venture between Geosyntec Consultants and Jacobs Engineering Group headquartered in San Diego, California, delivers environmental remediation, engineering, and technical services to the Department of Defense as a prime contractor on a single five-year, $100 million IDIQ vehicle through March 2027, with no subcontracting footprint in the available award record.

The joint venture competes full-and-open with no set-aside designations across its federal portfolio. Geosyntec Jacobs is a child entity of Ch2M Hill Companies, LTD., a for-profit corporate parent.

The customer base is heavily concentrated on Naval Facilities Engineering Command (NAVFAC), which accounts for 54 of 63 awards (86% of the award count) and $163.4 million of $175.4 million combined potential value (93%). The joint venture also serves the United States Marine Corps Air Ground Combat Center (3 awards, $5.6 million), the United States Marine Corps (1 award, $3.6 million), the Department of the Navy as a separate funding agency (1 award, $2 million), and smaller task orders from the Naval Supply Systems Command and the Office of the Secretary of Defense. This concentration reflects Geosyntec Jacobs' role as the dominant prime on NAVFAC's Environmental Science and Engineering Contract (ESEC) vehicle.

All work is performed under a single parent vehicle — the ESEC Indefinite Delivery, Indefinite Quantity contract (N3943022D2400) — through which NAVFAC has issued 62 task orders valued at $75.4 million combined potential. Task orders range from $10,000 minimum-guarantee orders to delivery orders exceeding $4 million. Geosyntec Jacobs' scope encompasses per- and polyfluoroalkyl substances (PFAS) remedial investigations, unexploded ordnance characterization and removal planning, groundwater modeling and optimization studies, long-term monitoring at installation restoration program sites, environmental compliance support, infrastructure resilience assessments, electric vehicle science and engineering, technology transfer program administration, and final status surveys across Navy and Marine Corps installations worldwide.

Recent representative work includes a $4.4 million Phase 2 PFAS remedial investigation at Naval Air Station Whidbey Island Ault Field in Washington (awarded April 2026, with human health and ecological risk assessment); a $5.66 million water quality surveillance and response task at Red Hill, Joint Base Pearl Harbor-Hickam in Hawaii (awarded September 2025); a $3.6 million natural hazard resilience assessment spanning Marine Corps Air Facility Quantico, Virginia and USMC installations in Okinawa, Japan (awarded September 2025); and a $2.49 million Defense Environmental Restoration Program task supporting Installation Restoration Program and Military Munitions Response Program work in San Diego, California (awarded August 2025). The joint venture frequently subcontracts specialized environmental consulting, geophysical surveying, laboratory testing, and surveying services to small businesses, including women-owned, minority-owned, and veteran-owned enterprises — examples include Meadows Cmpg, Inc. (Economically Disadvantaged Women-Owned Small Business) on long-term monitoring at Indian Head Naval Surface Warfare Center, EA Engineering, Science, and Technology, Inc. on ecosystem restoration at Nu Upia Ponds, and GSI Environmental Inc. on groundwater remediation and PFAS support.

Activity has grown from 5 awards in 2022 to a peak of 18 in 2025, with 16 awards in 2024. As of mid-2026, the source reflects 5 awards year-to-date. Twenty-one awards with combined potential value $27.1 million have ultimate completion dates in the next twenty-four months, representing significant recompete exposure on the ESEC vehicle as individual task order performance concludes through mid-2027. The underlying ESEC contract itself expires March 31, 2027, making NAVFAC's recompete decision and award timeline a critical milestone for the joint venture's federal pipeline.
