Key personnel must be Texas-licensed Professional Engineers with TxDOT precertifications in hydraulic design categories, and resumes must include licensure numbers, experience, and availability starting October 1, 2026. The solicitation requires strict adherence to formatting guidelines: proposals must be divided into four sections with page limits of two pages for the transmittal letter, five pages for the statement of qualifications, and one page per resume, with all documents labeled by vendor name and job number. Submissions are exclusively via the Bonfire portal by June 1, 2026. M/WBE participation is mandatory with a 19.60% goal, requiring certified firms to demonstrate Significant Local Presence through three prior contracts in specific Texas counties and maintain a physical office within those areas. Contractors must submit Good Faith Efforts documentation if the goal is not met, along with letters of intent and certifications from approved agencies. Insurance requirements include general liability with additional insured endorsements and a 30-day cancellation notice.
