The Navy Installations Command awarded a multiple-award Indefinite Delivery/Indefinite Quantity contract to ECC Diego Garcia LLC on September 10, 2025, with a ceiling value of $1.5 billion and an ultimate completion date of September 9, 2033. This Design-Build/Design-Bid-Build Multiple Award Construction Contract provides general building construction services at Naval Support Facility Diego Garcia in the British Indian Ocean Territory, with no small business set-asides applied. The scope encompasses repair, renovation, alteration, demolition, new construction, and associated design services for military infrastructure at the facility. Individual task orders are anticipated to range from $150,000 to $50 million, with the contract structured to support critical facility maintenance and infrastructure improvements over its eight-year period of performance.

The original pre-solicitation notice, posted October 2, 2023, sought capable contractors meeting the Commercial and Institutional Building Construction classification (NAICS 236220) to support the Navy's facility requirements. Per a bilateral agreement between the U.S. and U.K. governments, priority consideration was extended to joint ventures composed of at least 60 percent U.S. and 20 percent U.K. firms. The contract awards no set-aside provisions, indicating competition among full-sized business entities. The initial task order awarded to ECC Diego Garcia LLC carries a firm fixed-price minimum guarantee of $100,000 with a completion date of September 9, 2030, demonstrating the commencement of service delivery under this vehicle for facility support operations in the strategically located Indian Ocean region.
