Env. Consulting Government Contracts in Illinois

In Q2 2026, Illinois has 6 active Env. Consulting Services opportunities distributed across 2 cities, but the market is top-heavy: Chicago commands 83% of all activity. Chicago, Scott Air Force Base together hold 100% of statewide deal flow. Contractors entering Illinois's Env. Consulting Services market should treat Chicago as the primary beachhead before expanding to secondary markets.

Illinois's Env. Consulting Services procurement is controlled by a narrow agency base: Environmental Protection Agency and Department of Veterans Affairs together account for 82% of all awards worth $125.2M in total obligated spending. This dual-agency dominance means contractors in Illinois must build relationships with both to access the majority of contract dollars. On the vendor side, the market is incumbent-heavy: the top 3 contractors — TETRA TECH, INC., Unknown, TROPICAL ENVIRONMENTAL INC — hold 84% of recent awards, meaning new entrants face significant barriers unless targeting recompetes or set-asides.

Illinois's Env. Consulting Services recompete pipeline contains 3 contracts approaching renewal windows in Q2 2026, valued at an estimated $82.0M combined. 3 of these (100%) carry high takeover signals, indicating agencies with a pattern of switching vendors at contract renewal. Department of the Army accounts for the largest share of upcoming recompetes, making it the priority agency for displacement-focused contractors.
