REPORT <br />To the Honorable Mayor and City Council <br />From the City Manager <br /> <br />May 8, 2017 <br /> <br />SUBJECT <br />Award of Contract – 2016-2017 Sanitary Sewer and Watermain Replacement Project <br /> <br />RECOMMENDATION <br />By motion, approve and authorize the City Manager to execute the contract documents <br />and award the standard form construction contract 00520 for the 2016-2017 Sanitary <br />Sewer and Watermain Replacement Project to the lowest responsible bidder, Casey <br />Construction Inc. of Emerald Hills, California for their low bid of $5,673,488; and, <br />authorize the City Manager to increase the contract amount, if necessary, up to 10% of <br />the original contract amount, not to exceed $6,240,825.80; and find that the project is <br />exempt from the requirements of the California Environmental Quality Act (CEQA) <br />under CEQA Guidelines Section 15302 (Replacement or Reconstruction) <br /> <br />BACKGROUND <br />The City systematically replaces sections of aging sewer and water infrastructure to <br />ensure the continued reliability of the system. Each year, staff identifies pipelines <br />wh i c h required excessive maintenance or which experienced repeated service <br />disruptions and target those pipelines for improvement. <br /> <br />On October 24, 2011, the City Council accepted the Water System Master Plan Report <br />and on January 28, 2013, a technical update to the 2008 Sanitary Sewer Master Plan <br />was finalized. These master plans directed staff to move forward with specific <br />recommendations for infrastructure improvements. The Water System Master Plan <br />prioritized the system pipeline replacement into seven priorities or programs. The Sewer <br />Master Plan Update prioritized the system pipeline replacement into four priorities. <br /> <br />Closed circuit television inspection review of Sanitary Sewer Basin Numbers 6 and7 were <br />also completed in 2015. Staff’s review of the inspection videos revealed numerous <br />defects in these sewer basins. A number of construction options for repair or <br />replacement were evaluated to determine the most cost-effective method for mitigation. <br />For this project, a traditional open trench method was chosen in order to replace the <br />identified pipe defects. <br /> <br />The proposed sanitary sewer and watermain replacement project will enhance the <br />condition and reliability of the sewer collection by minimizing infiltration and inflow and <br />and enhance the water system by providing improved fire protection.
