Contra Costa County Public Works Department is requesting qualifications for on-call transportation engineering services, with Statements of Qualifications due August 27, 2026 at 5:00 p.m. The County intends to establish a prequalified shortlist of multiple consultant firms to provide transportation planning, design, and analysis services over a three-year initial period (2026–2029), with an option to extend for an additional two years.
