About this IDV

The Naval Facilities Engineering Command (NAVFAC), a defense agency, awarded a $100 million Indefinite Delivery, Indefinite Quantity (IDIQ) contract called the Environmental Science and Engineering Contract (ESEC) to Geosyntec Jacobs A Joint Venture, a for-profit organization. The ESEC contract enables NAVFAC to issue task orders ranging from $40,000 to $3 million for a wide range of architectural, engineering, and environmental services to support U.S. Navy, Marine Corps, and Base Realignment and Closure (BRAC) installations globally. The contracted services include environmental restoration, program support, studies, testing, consultation, technology demonstration, and administrative assistance. The contract does not have any set-aside designations. Task orders awarded under the ESEC cover diverse projects such as PFAS investigations, remedial investigations, environmental compliance studies, groundwater modeling, electric vehicle science and engineering support, and infrastructure assessment at various Navy and Marine Corps locations.

The ESEC contract was awarded in November 2021 and runs through March 2027. It provides streamlined access to specialized technical services across environmental, facilities, and expeditionary operations domains. The task orders reviewed demonstrate Geosyntec Jacobs A Joint Venture's expertise in delivering cost-plus-fixed-fee and firm-fixed-price contracts for NAVFAC, supporting critical environmental and infrastructure requirements at defense installations in the U.S. and overseas.
