RIVERSIDE PUBLIC UTILITIES M3Board Memorandum P U B L I C U T I L I T I E S BOARD OF PUBLIC UTILITIES DATE: May 21, 2010 ITEM NO: 4 SUBJECT: OVERHEAD AND UNDERGROUND STRUCTURE INSTALLATION FOR CIRCUIT 1533 FEEDER LOAD RELIEF PROJECT WORK ORDER NO. 1010201 ISSUE: Board approval is requested for Work Order No. 1010201. RECOMMENDATION: That the Board of Public Utilities approve the estimated capital expenditure of $258,317.82 to install overhead and underground structures along Overlook Parkway and over the Arroyo between Sandtrack Road and Magnon Court. BACKGROUND: Limitation on available ties and capacity, coupled with the extreme distances from Freeman and Orangecrest Substations servicing this area, requires a new feeder from the Orangecrest Substation. The proposed project involves the construction of a new 12 kilovolt (kV) electric distribution circuit to support existing and future electric load requirements in the Canyon Crest and Alessandro Heights neighborhoods off Overlook Parkway. A route has been identified through system studies performed by Riverside Public Utilities (RPU). The alignment for the proposed 12 kV circuit generally runs northerly to southerly along Trautwein Road and Alessandro Boulevard from John F. Kennedy Boulevard to Overlook Parkway. The alignment then runs generally easterly to westerly on Overlook Parkway from Alessandro Boulevard to Crystal View Terrace. This project consists of an environmental initial study, trenching approximately 331 feet along Overlook Parkway, installation of conduits, structures, the placement of underground cable in existing structures and overhead facilities spanning the arroyo at two locations. The electrical engineering was performed by RPU. All civil work including trenching, conduits, vaults and other infrastructure work will be performed by contractor forces through the competitive bid process. Electrical work will be performed by RPU field forces. FISCAL IMPACT: The capital expenditure for the project is estimated to be $258,317.82, this includes all construction, environmental study, contingencies, construction management, inspection and design, as summarized in the following table: % Of Total Construction-Electric Conduit & Structures $145,817.41 56.45% Construction-RPU Electrical Work $53,618.67 20.76% Environmental Study $34,300.00 13.27% Contingency (10%) $14,581.74 05.65% Design, Construction Management, Ins ection $10,000.00 03.87% Subtotal: $258,317.82 100 % Funds are budgeted and available for this project in the Major Feeders Account No. 6130000-470633.
