Diego Garcia and British Indian Ocean Territory Multiple Award Construction Contract 2021 - 20206

Naval Facilities Engineering Command is procuring design and construction services for U.S. Navy Support Facility Diego Garcia, British Indian Ocean Territory under a multiple-award Master IDIQ with a shared ceiling of $249 million and a last date to order of September 2, 2026—roughly one month of ordering authority remaining.

This vehicle carries a structural constraint: under bilateral U.S.-U.K. agreement, all construction contracts must be awarded exclusively to U.S.-U.K. joint ventures with management control vested in the U.S. partner and no less than 60% U.S. and 20% U.K. participation. This restriction materially shapes the competitive field.

The vehicle is nearly fully obligated. Of the combined $471.3 million potential value across 121 task orders awarded since September 2021, $470.5 million (100%) has been obligated. Ordering activity peaked in 2025 at 36 orders, then slowed to 6 orders in 2026 through April, consistent with the approaching September 2026 deadline.

Three primes dominate the work: Mvl-Bromgrove JV LLC holds 45 orders worth $189.2 million combined potential value; Black Construction / Mace International Joint Venture holds 20 orders worth $154.9 million; and JSK Diego Services LLC holds 43 orders worth $100.3 million. Together these three capture roughly 88% of the awarded potential value. ECC Diego Garcia LLC (11 orders, $25.9 million) and Parsons-Colas UKP JV (2 orders, $1 million) comprise the remainder.

Department of the Navy Installations Command funds 78 orders ($316.6 million combined potential value), representing roughly 67% of total activity. Defense Logistics Agency Energy funds the next largest block (13 orders, $60.7 million). The remainder disperses across Naval Facilities Engineering Command, Pacific Air Forces, and Navy Office of Naval Research.

All 121 task orders are unrestricted (no set-aside designations). Task order values span from under $300,000 to $43.5 million. Representative recent orders include a north parking apron repair at $43.5 million, an overhead feeder repair at $32.8 million, approach lighting repair at $7.9 million, and routine HVAC replacements ranging from $900,000 to $3.7 million. Work covers airfield repair, mechanical and electrical systems, fire protection, water treatment, fuel handling, building renovation, and site infrastructure.

All performance occurs at Naval Support Facility Diego Garcia. Competition for remaining 2026 orders will be confined to the established JV base, and new entrants would need to structure qualifying partnerships before the September deadline.
