About this IDV
Black Construction/Mace International Joint Venture, a Guam-registered partnership, holds a multiple-award indefinite delivery/indefinite quantity construction contract valued at $448 million with an ultimate completion date of September 2, 2026. Awarded by Navy Installations Command on September 3, 2021, this contract provides design-build and design-bid-build construction services supporting U.S. Navy shore facilities at Naval Support Facility Diego Garcia in the British Indian Ocean Territory. The contract structure permits task orders ranging from $150,000 to $50 million and encompasses general building construction, repair, renovation, alteration, demolition, and necessary design work. The underlying solicitation, issued as a pre-solicitation notice in April 2020, required that all contractors operating at Diego Garcia be U.S.-U.K. joint ventures with management control vested in the U.S. partner and minimum participation thresholds of 60 percent U.S. and 20 percent U.K. ownership, reflecting the bilateral defense agreement governing construction activities at this strategic overseas location.
Through the current contract period, the joint venture has executed 19 substantive task orders totaling approximately $160 million, demonstrating significant infrastructure modernization and maintenance across the facility. Delivered projects include electrical infrastructure upgrades (power pole replacement, pad-mounted switch installation, electrical system repairs), mechanical systems work (water tank replacement, motor control center repairs, air conditioning unit replacement, standby generator installation), facility renovations (door replacement, roof repairs, incinerator building repairs, geodetic surveillance operations building repairs), specialized infrastructure projects (antenna installation, parking apron repairs, road repairs), fire safety systems (fire alarm system replacement, fire hydrant repairs), vehicle support systems (exhaust extraction installation), and environmental remediation (lead and asbestos abatement). Task orders have been funded by Navy Installations Command, Naval Facilities Engineering Command, Office of Naval Research, U.S. Fleet Forces Command, and Defense Logistics Agency Energy, reflecting the broad facility support requirements across multiple Navy operational commands at this remote but strategically critical installation.
