26RFSQ69 Engineering Development Services

Williamson County is seeking qualified engineering firms to provide specialized review and quality assurance services for third-party developer designs related to plats, driveways, floodplain management, and drainage systems. The scope of work includes supporting county staff in daily permit reviews and delivering as-needed engineering assistance for projects under the Road Bond Program, Road and Bridge Division, Development Services & Drainage Division, and County Facilities, with no involvement in original infrastructure design such as roadway or drainage conveyance systems. The county anticipates selecting approximately three firms though the Commissioners Court retains discretion to choose more or fewer based on evaluation outcomes. All work must focus exclusively on reviewing designs submitted by outside developers rather than creating original engineering plans for the county. The solicitation, numbered 26RFSQ69 and titled Engineering Development Services, was posted on July 31, 2026, with a response deadline of August 18, 2026. Proposals must be submitted through the designated online portal, and all inquiries should be directed to Sandra Malcolm at sandra.malcolm@wilcotx.gov. The contract is administered by Williamson County, Texas, with performance expected to occur within the county’s jurisdiction. This opportunity is open to engineering firms with demonstrated expertise in plat and drainage review, FEMA floodplain compliance, and quality assurance processes for development projects, but excludes those seeking to perform original design work for the county's infrastructure.
