Explanation
1. BACKGROUND: This legislation authorizes the Director of Public Utilities to enter into an engineering agreement with Chester Engineers for the Scioto Main Large Diameter Condition Assessment Project, CIP 650725-100012. This project will extend the remaining useful life of the most critical sewers within the City by making necessary replacements. It will also lower operation and maintenance costs by increasing the pipe flow efficiency. This project will provide incremental funding to allow for the systematic inspection and rehabilitation design of the City's large diameter sanitary sewer infrastructure. This work is in accordance with the requirements of the OEPA consent order. Sewers to be included are the Scioto Main (North), Scioto Main (Middle), Upper Scioto West, and Upper Scioto NW Branch. These sewers run approximately from the intersection of Riverside Drive and Bridge Street in Dublin, heading south-southeast to its terminus at the junction chamber for the Scioto Main and West Side sewers. Total length is approximately 104,800 lineal ft. It will also reduce the risk of collapse which could cause sanitary sewer overflows (SSO) to adjacent water ways or water in basements (WIB's).
2. PROJECT TIMELINE: After issue of the notice to proceed (NTP) (summer of 2017) the term of the engineering agreement is approximately 1.5 years and the estimated ending month and year of the agreement is December, 2018.
