6.2.A. - Page 1 <br /> RE PO RT <br /> To the Honorable Mayor and City Council <br /> From the City Manager <br /> August 22, 2011 <br /> SUBJECT <br /> Final Acceptance — 2010-2011 Watermain Replacement Project <br /> RECOMMENDATION <br /> By motion, accept the 2010-2011 Watermain Replacement Project and authorize the <br /> release of bonds and retention, according to city procedures. <br /> BACKGROUND <br /> The city systematically replaces sections of aging watermain infrastructure to ensure the <br /> continued reliability of the system and to provide for improved fire protection. Annually, <br /> staff from Engineering and Transportation and Public Works Services departments <br /> identify pipeline sections that experienced service disruptions, excessive maintenance <br /> requirements, or capacity limitations due to age and target those sections for <br /> replacement. This year, the 2010-2011 Watermain Replacement Project replaced <br /> approximately 5,820 linear feet of deteriorated cast iron water pipeline with more <br /> durable PVC pipe. Improvements also included replacement of residential services, fire <br /> hydrants, and water valves to improve the quality, performance and reliability of the <br /> water system for the area residents. <br /> On September 27, 2010 the City Council awarded the construction contract for the <br /> 2010-2011 Watermain Replacement Project to Casey Construction, Inc., of Redwood <br /> City for the amount of $1,049,549.00. The project has been successfully completed in <br /> accordance with the plans and specifications for a total cost of $1,123,282.13 which is <br /> 7.02% higher than the original bid amount. One (1) change order was issued for the <br /> amount of $73,733.13 resulting from quantity adjustments and unforeseeable field <br /> conditions. The change order included a credit of $3,535.00 for quantity adjustments, <br /> $13,235.37 in negotiated extra work, and $64,032.76 in force account payments. <br /> ALTERNATIVES <br /> Council may choose not to accept the project or authorize the release of bonds and <br /> retention which would be contrary to the terms of the contract, prior Council action, and <br /> public contracting code. <br />
