About Affinis Corp
Affinis Corp, a small-business–certified civil engineering and environmental consulting firm headquartered in Overland Park, Kansas, operates as a prime contractor (100% of recent awards) delivering architect-engineering services, infrastructure condition assessments, and facility operations and maintenance support to the U.S. Army Corps of Engineers. The company is a for-profit Subchapter S corporation that competes predominantly under total small business set-asides on individual task orders, though not all orders carry set-aside designations.
Affinis has built a deeply concentrated footprint with the Army Corps of Engineers across multiple district offices. The Department of the Army Corps of Engineers Finance command anchors the largest single value ($36 million) through a single indefinite delivery contract, while the Engineering District Kansas City (25 awards, $14.9 million combined potential value) and Engineering District Omaha (4 awards, $5.6 million combined potential value) account for 97% of awards by count and 91% of combined potential value across the entire award portfolio. The Air Force Air Mobility Command represents a single $77 thousand outlier. This concentration reflects Affinis's regional and programmatic specialization: the firm operates primarily in Kansas and Missouri, performing stream asset and condition assessments, combined sewer overflow projects, wastewater treatment facility work, storm system improvements, and facility operations and maintenance updates at military installations including Fort Riley and Whiteman Air Force Base.
Recent representative work includes a $275,537 delivery order from USACE Kansas City District (December 2025) for multi-county stream asset condition assessment in the Kansas City area (completion December 2026), a $522,198 firm fixed-price delivery order for the Atchison combined sewer overflow project (September 2024, completion September 2026), and a $181,912 delivery order for Manhattan Facilities Operations and Maintenance Update (July 2024, completion May 2026). Affinis places task orders under two primary USACE indefinite delivery contracts: W912DQ14D1004 (21 task orders, $6.1 million combined potential value) and W912DQ19D1012 (9 task orders, $4.9 million combined potential value), along with the USACE Dam and Levee Safety program vehicle (4 task orders, $5.6 million).
Activity has been episodic rather than growth-oriented — one award in 2025, two in 2024, two in 2022, one in 2020, and four in 2019 — with only two awards (combined potential value $798 thousand) facing completion inside the next twenty-four months. The vendor carries a joint-venture subsidiary, Affinis Freese And Nichols JV, structured as a small business joint venture. Combined potential value across all 37 awards stands at $64.7 million, with $16.5 million obligated (26% utilization), reflecting the contract-funding profile of task orders under indefinite vehicles where not all ceiling value is drawn.
