ENDIST Tulsa

The Department of the Army Corps of Engineers Engineering District Tulsa, a sub-agency of USACE within the Department of Defense, is the principal design, construction, and real-estate contracting arm for military facilities, civil works projects, and infrastructure across the Southwestern Division footprint. The district manages contracts for military base construction, locks and dams, power generation, water resources management, and related engineering services across Oklahoma, Kansas, Arkansas, and the Southwest region.

The Tulsa District has awarded 7,562 federal contracts since 1997, totaling $8.69 billion in combined potential value with $9.1 billion in combined dollars obligated. Recent contract activity shows acceleration: 67 awards in 2022, 53 in 2023, 73 in 2024, 153 in 2025, and 129 year-to-date in 2026. The most recent recorded award date is August 3, 2026. Competition is highly fragmented across 2,220 distinct prime contractors; the top five primes by award count hold only 12 percent of recent awards over the last five years. By potential value, the top five hold just 2 percent, indicating that contracts are distributed widely across the contractor base. Southwind Construction Services, LLC leads by value with 10 awards totaling $81.4 million combined potential value; Diversified Construction Of Oklahoma, Inc. ranks second with 9 awards and $54 million. Federal Contracts LLC leads by count with 14 awards but only $521 thousand in combined potential value, reflecting a portfolio dominated by smaller task orders and below-threshold purchase orders.

The set-aside mix is dominated by unrestricted procurement: 48 percent of awards carry no set-aside designation. Small-business set-asides account for 33 percent of awards, with 8(a) Sole Source comprising 13 percent. HUBZone, Competitive 8(a), and Service-Disabled Veteran-Owned Small Business together represent 5 percent; Woman-Owned Small Business and economically disadvantaged variants account for less than 1 percent combined.

The Tulsa District also administers grant funding, though at minimal scale: two grant awards totaling $444 thousand in combined federal dollars obligated. Colorado State University received one Cooperative Agreement for $350 thousand; The Student Conservation Association, Inc. received one for $94 thousand. Both awards fall within the last two years (first grant award May 23, 2025; most recent June 15, 2026), and all grant assistance is structured as Cooperative Agreements.
