About this vehicle
The Department of Homeland Security US Coast Guard awarded the National Multiple Award Construction Contract III (NMACC III) Master IDIQ on September 29, 2023, with a shared ceiling of four billion dollars and ordering authority through September 28, 2028—approximately two years and two months of remaining open ordering window. The vehicle is unrestricted and carries no set-aside designations.
Twenty-eight task orders have been awarded since inception, with combined potential value of $1.64 billion obligated in full. Ordering momentum accelerated in 2026, with eight orders awarded in the first six months of the year following a slower 2024 (four orders) and moderate 2025 (six orders). The 2023 awards consisted primarily of minimum-guarantee orders ($10,000 each) distributed across ten prime contractors to satisfy the IDIQ's guarantees; substantive work orders began flowing in earnest from late 2023 onward.
The vehicle funds general construction, marine construction, renovation, alteration, and repair projects across the 50 United States, Puerto Rico, Guam, and the U.S. Virgin Islands. Work is executed under design-build and design-bid-build delivery methods. Recent task orders reflect Coast Guard facility modernization and infrastructure priorities: shore construction and recapitalization at bases in Charleston, South Carolina; Kodiak, Alaska; Elizabeth City, North Carolina; and Cape May, New Jersey; waterfront improvements supporting homeporting of new Polar Security Cutters at Base Seattle; and training facility renovations.
The Whiting-Turner Contracting Company dominates the vehicle by both order count and value, holding 10 orders totaling $882 million in combined potential value (approximately 54% of all task-order value). Brasfield & Gorrie LLC, The Haskell Company, and Tutor Perini Corporation collectively account for approximately 28% of value; five additional primes hold the remainder. Task orders range from $7 million to $400 million, with firm fixed-price pricing predominant. Twenty-seven of the 28 orders (96% of portfolio value) fund Coast Guard operations; one $31.6 million order funds the Federal Law Enforcement Training Center.
