Topographical Survey- 2021 Northeast Neighborhood Sanitary Sewer- Gaston Road Extension

The City of Madison Engineering Division in Wisconsin is seeking a topographical survey design service for the 2021 Northeast Neighborhood Sanitary Sewer-Gaston Road Extension project. The procurement involves a comprehensive topographical survey of a proposed sanitary sewer main extension on Gaston Road, Seminary Springs, and County Highway T in the Town of Burke. A registered land surveyor must conduct the survey, extending 15 feet beyond the right-of-way and creating a digital terrain model with cross-sections recorded at 25-foot intervals perpendicular to the street centerline. The survey must document all topographical features including utilities, break lines, trees, buildings, and structures, and measure invert elevations for culverts, pipes, and sewer structures. Specific deliverables include three digital design files compatible with Autodesk Civil 3D 2020, ASCII text files of survey shots, utility verification correspondence, and documented structure invert elevations. The proposal was due by 4:00 PM on November 16, 2021, with project award anticipated by November 17, 2021, contract execution by November 22, 2021, and final survey delivery required by January 1, 2022.

The Request for Proposals does not explicitly mention set-aside designations or restrictions for disadvantaged enterprises. The contract requires precise horizontal precision standards of 0.07 feet plus 50 parts per million and specific vertical standards with appropriate monument placement. Contractors without a Registered Land Surveyor (RLS) on staff will not be considered. The contractor must obtain three horizontal and vertical control points from the City of Madison, establish additional control as needed, and comply with Diggers Hotline notifications, OSHA standards, and MUTCD traffic control requirements. Utility verification letters must be sent to non-City utilities including MG&E, Alliant, and AT&T. The contract includes a payment retention mechanism where a minimum of 10 percent of the final payment will be withheld pending acceptance of completed and satisfactory deliverables by the City. While a specific contract value is not stated, the detailed technical requirements suggest a specialized and potentially substantial surveying project for the municipal infrastructure development.
