Construction Manager at Risk (CMAR) - Effluent and Wastewater Pipelines and State Route 89 Improvements

The City of Prescott is seeking a qualified firm to provide design phase preconstruction services and construction services as the Construction Manager at Risk (CMAR) for the Effluent and Wastewater Pipelines and State Route 89 Roadway Improvements project.

The estimated project construction cost is approximately $25M, including the cost for a new replacement 24-inch effluent force main, a new 24-inch gravity sewer line, and State Route 89 road work including safety, operation, and capacity improvements which include above grade rock removal, roadway improvements, cross-traffic intersection improvements including grade adjustment, sight visibility lines, and turn restrictions, limited turn lanes, a realignment of the southbound approach lanes to the Willow Lake Road roundabout, a north to south turnaround near the midway point between the Willow Lake Road and Phippen Trail roundabouts, an extension of the southbound merge lane south of the Phippen Trail roundabout, and a frontage road on the northbound side of the roadway just north of the Willow Lake Road roundabout.

The project is currently 15% designed and the design consultant, Kimley-Horn and Associates, Inc. plans to complete design by February 2027. The City would like to start construction in March 2027 and complete construction by the end of 2028.

The project is an important part of the City's centralization effort by replacing an undersized and failing effluent pipeline and adding a second wastewater pipeline in the State Route 89 corridor. Once complete, the project will increase pipeline capacity and centralize wastewater treatment and effluent distribution from the Airport Water Reclamation Facility (AWRF). The project will also make roadway improvements to help improve safety, including cross-traffic roadway access and visibility along and at intersections, and improve and maintain efficient traffic flow.
