Set Public Hearing For <br /> CONTINUED TO <br /> 12 <br /> FILE NUMBER <br /> CITY MANAGER <br /> <br /> RECOMMENDED ACTION <br /> <br /> Increase the contingency for the contract with Guerrero Backhoe Service, Inc. for the Recycled <br /> Water Conversion Project by $100,000 to a total estimated contract amount of $324,526 and <br /> authorize the City Manager to execute change orders up to the contingency amount. <br /> <br /> <br /> <br /> DISCUSSION <br /> <br /> On December 7, 2009, the City Council awarded a contract for the Recycled Water Conversion <br /> Project to Guerrero Backhoe Service, Inc. in the estimated amount of $195,240 plus a <br /> contingency of $29,286 totaling $224,526. 526. Unforeseen field conditions <br /> 9 $ not shown in the contract <br /> at Centennial Park have prompted additional work to complete the Water Conversion Project. <br /> The existing water supply system at Centennial Park continuously loops throughout the entire <br /> park with connections to Godinez High School, the lake, and the soccer fields. Water is <br /> provided for daily use in the school and the park, as well as irrigation water for the landscaped <br /> areas. To convert the irrigation system from potable water to recycled water, the existing water <br /> pipes and apparatus will need to be disconnected and regrouped into two separate systems: <br /> potable water for domestic use and recycled water for landscaping. <br /> After construction started, it was discovered that the underground piping system was <br /> significantly different from what was shown on the plans, which were prepared based on old as- <br /> built records. To rectify the situation, exploratory excavations have been performed at several <br /> connection points to determine the actual layout of pipes, and plans have been revised based on <br /> the result of the investigation. The revisions require additional pipes and equipment to provide <br /> separate domestic water and recycled water for each area, and to provide temporary water to <br /> the school and the park until the conversion is completed. <br /> <br /> <br /> 23B-1 <br />
