Dibble provided construction management and inspection services for the City of Phoenix for the 38th Street Relief Sewer project, located within the Town of Paradise Valley. This Construction Manager at Risk (CMAR) project installed approximately 3,500 linear feet of new 8-inch sanitary sewer line along 38th Street and 38th Place from Lincoln Drive to Bethany Home Road. The 8-inch gravity sewer main will also tie into the existing City of Phoenix wastewater collection system upstream of Lift Station 54 and allow for abandonment.
Work included installing 22 new sewer manholes, approximately 400 linear feet of 6-inch sewer services, and two drainage inlets with approximately 80 linear feet of new RGRCP 18-inch storm drain crossing. Additional scope included lane modifications to adjust the intersection of 38th Place and Berridge Lane to a “T” intersection, restoration of signing and striping, and landscaping restoration.
The project was located in a high-traffic residential area. The Dibble CM team met regularly with City officials, residents, HOA representatives, and other stakeholders to inform them of the project status and provide up-to-date information on lane closures and other neighborhood access restrictions. Our diligent oversight and tracking of rock excavation ensured accurate quantities and helped control costs.
