About this vehicle
The Department of the Army Corps of Engineers Engineering District Galveston awarded a Master IDIQ for horizontal construction services on April 8, 2025, with ordering authority extending through April 8, 2033. The vehicle operates under no set-aside and carries a $7 billion shared ceiling.
The MATOC procures Design-Build and Design-Bid-Build construction services for flood and storm damage reduction projects within the Southwestern Division, including levees, floodwalls, drainage structures, pump stations, sector gates, channel widening, bridges, and armoring. The vehicle supports civil works, operations, military construction, and Interagency and International programs.
All 15 task orders awarded to date carry $430.6 million in combined potential value, with 100% obligated. Kiewit US Contractors Co dominates the vehicle, holding a single delivery order valued at $404.2 million with ultimate completion in January 2030—a flagship PAV04 SEED PROJECT order covering ITR review concurrent with QC inspections and RFC certification. Ahtna-Great Lakes E&I JV holds the second-largest order at $26.4 million (Delta Pump SEED PROJECT, completing October 2027), while the remaining 13 primes—Gulf Coast Constructors LLC, Gulf Coast Builders LLP, and Slsco LTD—each hold single orders carrying $2.5 thousand minimum guarantees. The concentration is stark: one firm accounts for 94% of obligated dollars.
Customer concentration is similarly narrow. The Department of the Army placed the Kiewit mega-order ($404.2 million), the Department of the Army Corps of Engineers Engineering District Fort Worth placed the Ahtna-Great Lakes order ($26.4 million), and the Engineering District Galveston placed the remaining 13 orders totaling approximately $33 thousand. Roughly 94% of obligation funds Army-level programs.
All task orders are firm fixed price. Delivery order ultimate completion dates range from October 2027 through April 2033. The portfolio shows limited recent activity (15 orders in 2025 following vehicle establishment); task-order momentum data beyond the initial award window is not yet available.
