D Street Reconstruction and Utility Design Services

The City of Petaluma is soliciting professional design services for the comprehensive reconstruction of D Street from Petaluma Blvd S to the city limits, focusing on the creation of bid-ready construction documents that incorporate Complete Street and Green Street principles. The scope encompasses integrating traffic calming measures, ADA accessibility enhancements, green infrastructure, and the replacement and upgrade of aging utilities including water mains, sewer mains, and stormwater systems. The selected consultant will manage the project through all design phases—30%, 60%, 90%, and final—conducting essential site investigations such as surveying and geotechnical analysis, and will provide up to eighty hours of support during bidding and construction for review of submittals and response to RFIs. Deliverables include detailed construction drawings in AutoCAD and PDF, technical specifications in CSI format, cost estimates, environmental permits, tree protection plans, and as-built documentation if required, all aligned with CALTRANS, NPDES, BASMAA, ADA, and California environmental regulations. The work must comply with the City’s General Conditions and adhere to prevailing wage and living wage requirements as certified through mandatory attachments. The solicitation, numbered 20260720021, is open for responses until August 28, 2026, with proposals required to be submitted electronically via email to the Principal Civil Engineer at the City’s Public Works Department. The technical proposal is limited to forty single-sided pages, excluding cover materials and resumes, with a separate fee proposal to be submitted as a distinct file. Evaluations will be based equally on the offeror’s responsiveness to the scope and proposed approach and their demonstrated experience delivering similar services to public agencies, with selection determined on a trade-off basis rather than lowest price. Contractors must hold an A.M. Best rating of A:VII or better, provide primary and non-contributory insurance with waiver of subrogation, indemnify the City against negligence or misconduct under California law, and avoid any organizational conflicts of interest as defined by state statute. All permits, licenses, equipment, and facilities are the contractor’s responsibility, and the City retains unfettered inspection rights throughout performance. Submission must comply with strict format rules, and any violation of prevailing wage, living wage, or disclosure obligations regarding past violations may result in disqualification or contract termination.
