Campus, Downtown, and East Washington Ave Sanitary Sewer Study

The City of Madison Engineering Division is soliciting advanced sanitary sewer modeling and planning services for the Campus, Downtown, and East Washington Ave study area. The project objective is to develop a calibrated 1D hydraulic model to assess current system capacity and analyze the impacts of future developments. Key deliverables include a maintainable sanitary sewer system model, a monitoring data collection plan, a calibration report, and a Modeling Guidance document to standardize future City efforts. The scope encompasses progress meetings, records review, field inspections of 125 manholes, flow monitoring at 20 sites, and the development of a Capital Improvement Plan. The contract was awarded to Carollo, who achieved the highest technical score and lowest price among five competing vendors. The initial award amount is 341,418 dollars, though the total project budget for 2026 is 500,000 dollars to allow for potential additional tasks such as smoke and dye testing. The period of performance begins with a kick-off meeting the week of February 16, 2026, and concludes by June 30, 2027. Administrative requirements include the submission of an Affirmative Action Plan for contractors with 15 or more employees and a strict prohibition of weapons at City work sites. Evaluation of proposals was based on a trade-off process weighted by cost at 30 percent, project understanding at 25 percent, team composition at 20 percent, relevant experience at 20 percent, and local vendor preference at 5 percent. Payments are issued upon the City's written acceptance of completed services and are contingent upon the approval of required workforce documentation.
