District Context & Mission Impact
This massive vertical construction contract vehicle is administered by the U.S. Army Corps of Engineers Tulsa District. The Tulsa District manages military construction, civil engineering, and base installation support across Oklahoma, southern Kansas, and northern Texas, supporting major defense installations such as Fort Sill, Vance Air Force Base, Sheppard Air Force Base, and Tinker Air Force Base. Federal installations require continuous vertical building upgrades, including secure administrative complexes, training facilities, maintenance hangars, and logistics warehouses. Establishing a robust $495 million shared IDIQ capacity enables USACE to rapidly issue competitive task orders for major design-build and traditional design-bid-build facility projects through summer 2030.
