The City of Chicago Department of Procurement Services is requesting qualifications for final design engineering services for the Far Southside Overflow Tunnel project on behalf of the Department of Water Management, with submissions due July 31, 2026 at 3:00 p.m. Central Time. The procurement carries contract-specific diversity goals requiring 26 percent Minority Business Enterprise (MBE) participation, 6 percent Women Business Enterprise (WBE) participation, and 1 percent Veteran-Owned Business Enterprise (VBE) participation.

The scope encompasses comprehensive professional engineering design services, including preparation of plans, specifications, and cost estimates for this municipal sewer infrastructure project.

The contract term is 36 months with an option to extend for up to 24 additional months in two one-year renewal periods. No total agreement amount is specified.

Evaluation occurs in three phases. Phase I assesses compliance and responsiveness on a pass/fail basis.

Phase III consists of oral presentations for shortlisted respondents. Additional pass/fail criteria include Economic Disclosure Statement compliance, legal actions review, insurance requirements, sexual harassment policy affidavit, conflict of interest disclosure, and acceptance of City terms and conditions.

A pre-submittal conference is scheduled for April 28, 2026 at 10:00 a.m. Central Time at 2 N. LaSalle Street, Chicago, Illinois; advance registration is required.
