Explanation
1. BACKGROUND: This legislation authorizes the Director of Public Utilities to enter a professional engineering agreement with Chester Engineers for the Blacklick Creek Main Trunk Sewer Large Diameter Sewer Assessment (LDSA) project, CIP 650725-100011. This work is in accordance with the requirements of the OEPA consent order and is consistent with the Division of Sewerage & Drainage’s Capacity, Maintenance, Operations, and Management (CMOM) plan. This project will provide inspection for one of the City's large diameter sanitary sewers. The limits for this project are from the northernmost manhole in the vicinity of the Blacklick Ridge Boulevard and Reynoldsburg-New Albany Road, to its connection point with the Big Walnut Outfall (North) near the intersection of Williams Road and I-270. The approximate total length of the sewer included in this project is 116,105 feet.
Work items for this phase of the project shall consist of field surveying of manholes, manhole inspections, closed circuit televising and man-entry inspections to assess the structural and operational condition of the large diameter trunk sewers identified on the project Exhibit, the providing of an Technical Memorandum outlining the structural and operational conditions of the sewers, and all other necessary items for the completion of the Memorandum.
2. Project Timeline: The initial sewer assessment phase of this project will have a duration of one year. A future contract modification may be necessary to perform design services on an emergency basis for the rehabilitation of various sewers if it is discovered during the initial assessment that significant defects exist within the sewers, and that these defects pose a significant risk to the public or adjacent properties. If they are necessary, the duration of these services would last through both design and construction phases, and would be approximately 2 years.
Future Modification: $1,200,000.00
