REPORT To the Honorable Mayor and City Council From the City Manager April 24, 2017 SUBJECT Final Acceptance – 2015-2016 Sanitary Sewer Replacement Project RECOMMENDATION By motion, accept the 2015-2016 Sanitary Sewer Replacement Project, and authorize the release of bonds and retention according to City procedures BACKGROUND The City systematically replaces sections of aging sewer infrastructure to ensure the continued reliability of the system. Each year, staff identifies pipelines that required excessive maintenance or experienced repeated service disruptions and targets those pipelines for improvement. Closed circuit television inspection review of Sanitary Sewer Basin Numbers 5B, 5F and 5H were completed in 2014. Staff’s review of the inspection videos revealed numerous defects in these sewer basins. A number of construction options for repair or replacement were evaluated to determine the most cost-effective method for mitigation. For this project, a traditional open trench method was chosen in order to replace the identified pipe defects. Furthermore, this project was designed compliant with the City’s Engineering Standards and accepted practices. ANALYSIS On May 14, 2016 the City Council awarded the construction contract for the 2015-2016 Sanitary Sewer Replacement Project to Casey Construction, Inc. of Emerald Hills for their responsive and responsible low bid of $3,121,340.00. The project replaced and furnished approximately 13,976 linear feet of existing 6-inch and 8-inch vitrified clay pipe (VCP) sewer main with new 6-inch, and 8-inch polyvinyl chloride pipe (PVC), 80 sanitary sewer manholes and 350 sanitary sewer laterals. The project area included Harding Avenue, Saint Francis Street, James Avenue, Quartz Street, Ruby Street, Hawes Street, Myrtle Street, King Street, Fairview Avenue, Virginia Avenue, Junipero Avenue, Valota Road, Oak Avenue, Oliver Street, McKinley Street, Johnson Street, Reese Street, Regent Street, Oxford Street and Poplar Avenue within Redwood City corporate limits. A map of the project area is attached. The project has been completed and approved by the City Engineer in accordance with the plans and specifications and within the timeframe allowed by contract for a total cost of $3,079,022.49 which is 1.36% less than the original bid amount.
