The contractor has consistently performed as a prime contractor with no documented subcontractor involvement, demonstrating in-house capability to execute diverse technical infrastructure projects. All awards have been issued by the Navy Installations Command as task orders under larger indefinite delivery/indefinite quantity multiple award construction contracts established through the U.S.-U.K. bilateral facility support framework.

ECC Diego Garcia LLC currently holds two active indefinite delivery/indefinite quantity contracts with the Navy Installations Command. The first IDIQ, awarded September 3, 2021, carries a $448 million ceiling value with an ordering period through September 2, 2026, and provides design-build and design-bid-build construction services supporting facility repair, renovation, alteration, demolition, and new construction at Naval Support Facility Diego Garcia. Under this vehicle, ECC Diego Garcia LLC has received twelve delivery orders with a combined value exceeding $25.3 million for diverse infrastructure projects. The second IDIQ, a newer multiple award construction contract awarded September 10, 2025, provides a significantly larger $1.5 billion ceiling value with services extending through September 9, 2033. This contract also encompasses design-build and design-bid-build construction services with anticipated individual task orders ranging from $150,000 to $50 million, enabling the contractor to support critical facility maintenance and infrastructure improvements across an extended eight-year period. Both IDIQs were established per bilateral agreements between the U.S. and U.K. governments to facilitate facility operations at the strategically important naval installation in the British Indian Ocean Territory, with no small business set-aside designations applied to either vehicle.
