Substantial completion must occur within 750 days after commencement of work.

The estimated construction budget is $75 million. A security deposit of 10 percent of the total bid amount is due with proposal submission. Award notification is expected in December 2026, with City Council agenda date in January 2027 and contract start date in February 2027.

Evaluation is based on responsive and responsible status (pass/fail), financial stability (pass/fail), technical competence (60 points maximum), and cost proposal (40 points maximum). Up to 5 additional local preference points are available for firms designated as City Businesses or Local Businesses under the Hire Houston First Program. The W/SBE participation goal is 0 percent. Proposers must submit resumes for key personnel with minimum ten years of experience, examples of similar completed projects from the past ten years, safety plans, quality assurance and control procedures, and project scheduling and change order management approaches.
