About this opportunity
The General Services Administration Public Buildings Service Office of Leasing, procuring on behalf of the Internal Revenue Service, has awarded a 36-month lease extension under contract GS-05B-18564 on a limited-sources basis on September 22, 2026.
The extension covers 65,316 ABOA / 75,111 rentable square feet at The Esplanade I, 2001 Butterfield Road, Downers Grove, Illinois, under existing lease number LIL18564. The current lease expires July 31, 2026, with the extension commencing August 1, 2026. The justification cites 41 U.S.C. 3304(a)(1) and rests on the rationale that the IRS is developing long-term space reduction and potential relocation plans, making lease extension in the Government's best interest to avoid costly holdover awards and relocation expenses during the planning period. Remaining at the current location prevents holdover status and allows continued operations without disruption. GSA conducted market research on July 1, 2026, using CoStar, LoopNet, and Chat GPT to validate that proposed rates are fair and reasonable. The Lease Contracting Officer (Stephanie Carlson) certified the justification on July 22, 2026, with approvals from the Leasing Branch Chief (Katrina Trimble), Competition Advocate (Gina DiTommaso), and Real Property Law Division (Robert Foltman).
