What Oneida Total Integrated Enterprises (OTIE) does

Oneida Total Integrated Enterprises (OTIE) is a full-service, multi-discipline engineering, science, and construction management firm operating as a wholly-owned subsidiary of Oneida ESC Group, LLC, itself wholly-owned by the Oneida Nation. Founded in 2000 and headquartered in Wauwatosa, Wisconsin, OTIE delivers two primary service lines: Environmental Services (remedial investigation, feasibility studies, remediation design and implementation, water/wastewater systems engineering, and fence-to-fence environmental compliance) and Engineering and Design Services (civil, mechanical, electrical, and structural design, asset management, and graphic design rendering). Its customer base is concentrated in U.S. federal agencies — principally the U.S. Army Corps of Engineers, Department of Defense, Air Force, Navy, EPA, USDA, and Fish and Wildlife Service — supplemented by state and local government and select international DoD work in Japan delivered through the OTIE-Merrick joint venture.

OTIE's commercial model rests on its tribally-owned SBA 8(a) status, which enables sole-source direct federal awards with no dollar threshold limitation — a structural procurement advantage unavailable to non-tribal competitors. The firm operates within a broader OESC ecosystem of eight subsidiaries covering environmental, engineering, construction, professional services, and economic development, allowing cross-subsidiary teaming on large federal procurements. Pricing flows through multi-year ID/IQ contracts and firm-fixed-price or cost-reimbursable task orders negotiated under FAR-compliant, DCAA-audited procurement and accounting systems. The firm's go-to-market is enterprise field sales oriented toward federal program offices and contracting officers, with no disclosed commercial SaaS, software product, or AI/ML offerings.

Revenue is not publicly disclosed. With 251–500 employees at the OTIE subsidiary level (and 500+ across the broader OESC Group), and applying typical revenue-per-FTE benchmarks for federal environmental and engineering services, OTIE's revenue most likely falls in the $50M–$100M range, though this estimate carries low confidence given the absence of any direct financial disclosure.
