Page 2 of 3 <br /> <br />The failure of this sewer main created imminent risks to public health, safety, and welfare due <br />to: (1) potential sewage overflows; (2) propagation of voids toward the roadway that could lead <br />to pavement collapse; and (3) threats to adjacent utilities, including water and storm drain <br />systems. To mitigate the imminent risk, the City issued an emergency time-and-materials <br />contract, not to exceed $500,000, to mobilize the contractor immediately. The contract covers <br />the replacement of the sewer pipe, repair and replacement of the water line, roadway <br />restoration, repaving, and any other work necessary to restore utility and roadway services <br />fully. <br /> <br /> <br />DISCUSSION <br />City crews could not perform these facility repairs due to the scale and complexity of the work. <br />The sewer line is located more than 13 feet below the roadway, requiring specialized shoring <br />systems, large-scale excavation equipment, and coordination with multiple utility crossings. In <br />addition, the length of pipe replacement and roadway restoration exceeds the City’s in-house <br />staffing capacity, equipment availability, and safety limitations. Engaging an on-call contractor <br />ensures the work is completed safely, efficiently, and in compliance with regulatory and <br />construction standards. <br /> <br />DPI Construction, Inc. is the City’s contractor currently working on a major storm drain CIP <br />project involving deep excavation and complex underground pipe replacement with similar <br />conditions to the Denker Drive situation. The necessary heavy equipment, shoring, and <br />materials are available at the City’s job site and were mobilized to replace the collapsed sewer <br />pipe. <br /> <br />Pavement restoration estimated at $100,000 will be completed by either DPI Construction, <br />Inc., one of the City's on-call paving contractors, or the Annual Resurfacing CIP contractor who <br />is performing work within the area, and is included in the $500,000 total project costs. <br /> <br />This project qualifies as an unforeseen, time-critical emergency. The extent of the pipe failure <br />was not visible from the surface and could only be detected through CCTV inspection. Once <br />identified, immediate action was required to prevent further sewer collapses, protect adjacent <br />water lines, and minimize service disruptions to residents. Delaying repairs would have posed <br />significant risks to public health, roadway stability, and surrounding utilities. <br /> <br />EQUITY AND SUSTAINABILITY <br />Not applicable, as this item is an emergency condition. <br /> <br />OUTREACH <br />Not applicable, as this item is an emergency condition. Staff informed residents of utility <br />outages by going door to door.
