About Gsina-Gilbane II JV LLC

Written by GovTribe AI ·

Gsina-Gilbane II JV LLC is a joint venture partnership between Gsina Construction Company and Gilbane, Inc., based in Flemington, New Jersey. The company is an SBA-certified 8(a) small disadvantaged business that specializes in environmental remediation and restoration services for federal military installations undergoing base realignment and closure (BRAC). As a federally registered vendor since February 2018, Gsina-Gilbane II JV LLC holds a single-award, $60 million indefinite delivery/indefinite quantity (IDIQ) contract with the Air Force Civil Engineer Center for BRAC environmental construction and optimization services across the Southwest region, covering California and Arizona through September 2030.

Since award of its primary IDIQ vehicle in September 2020, Gsina-Gilbane II JV LLC has received over $25 million in cumulative delivery orders from the Air Force Civil Engineer Center for environmental restoration work at former military installations, including George Air Force Base in Victorville, California and Williams Air Force Base in Mesa and Chandler, Arizona. The company's service offerings encompass a comprehensive range of environmental remediation activities, including groundwater sampling and monitoring, remedy optimization and long-term monitoring (LTM), treatment system design and construction, vapor intrusion evaluations and investigations, remedial action optimization (RA-O), five-year reviews, land use controls (LUCS) implementation, and base-wide condensate treatment system construction. Delivery orders issued to the joint venture have been structured as firm fixed-price contracts without set-aside designations, though the underlying IDIQ contract was awarded as an 8(a) total small business set-aside. Individual task orders have ranged substantially in value, from approximately $154,000 to over $3.2 million, with recent awards in September 2025 including a $1.59 million delivery order for environmental remediation at Williams Air Force Base and a $1.025 million order for BECOS Southwest Region services. This consistent stream of contract awards demonstrates Gsina-Gilbane II JV LLC's established expertise and capability in supporting the Air Force's environmental stewardship mission at closed and realigning installations.
