6.1.G. - Page 1 RE PO RT To the Honorable Mayor and City Council From the Cit Mana er January 14, 2013 SUBJECT Award of Contract —Water Main Seismic Improvement Project RECOMMENDATION Approve, by motion, the contract documents and award the standard form contract for the Water Main Improvement Project to Caggiano General Engineering, Inc. of EI Dorado Hills, Ca for their responsive and responsible low bid of $209,000.02 and authorize the City Manager to increase the contract amount, if necessary, up to 10% of the amount awarded, not to exceed $230,000.00. BACKGROUND On October 24, 2011, the City Council accepted the Water System Master Plan Report and directed staff to move forward with specific recommendations for future Council consideration. The Water System Master Plan forecasts water demand for new development and redevelopment activities anticipated by the city's General Plan; analyzes and identifies improvements for reliable performance during normal and emergency conditions, such as fires and earthquakes; and prioritizes capital improvements to the system for the next 20 years. The Water System Master Plan includes the groundwork for an integrated seismic improvement program that prioritizes projects based on criticality, funding levels, cost benefit ratios, and the city's level of service expectations. Seismic improvement projects will be designed and constructed over the next five years to increase the reliability of water tanks, pump stations, and pipes during significant seismic events. ANALYSIS This project is one of the high-priority seismic improvement projects recommended in the Water Master Plan. It aims to retrofit the existing 16" steel pipeline at Bridge Parkway and the existing 8" steel pipeline at Island Drive to eliminate joint leakages and strengthen the pipes for better performance in an earthquake. The project will also provide a new protective coating for the 16" pipeline and new cathodic protection anodes for the 8" pipeline to protect them against the harsh environment and extend their service lives. Both pipelines are hung from bridges in the Redwood Shores area. The seven bids received on November 20, 2012, are summarized in the table below.
