RECOMMENDATION: That the Board of Public Utilities approve the estimated capital expenditure of$70,353.50 for Emergency Work Order No. 1323268 in accordance with Article XII, section 1202(2) (b) for the City of Riverside Charter. BACKGROUND: On Monday April 8, 2013, a section of 12 kV Cable in Conduit (CIC) faulted on Copper Lantern Drive and Carnation Court (Attachment 1). CIC was a technology developed in the late 1960s where the cable is pre-installed in the conduit before it is installed in the trenches below ground. This type of installation makes it very difficult to remove faulted cables from the conduit. In order to facilitate restoration and repairs, crews have to install temporary cables on the ground and design a more permanent installation. Contract crews from Southern Contracting Company, a member of the Contractors' Panel for Energy Delivery Work, were immediately directed to install 400 feet of trenching and 555 feet of conduit. A deteriorated top section of a primary structure was also replaced to restore the electrical system to its normal operating condition. The work started on April 9, 2013, and was completed on April 11, 2013. Street repairs continued until April 23, 2013. The total cost for contract work was $56,977.63. City crews installed replacement cable and removed the temporary cable with multiple crews on April 12, 2013, for a total amount of$13,375.87. Article XII Department of Public Utilities of the Riverside City Charter; Section 1202 Same—Powers and duties; (b) (2) allows work to be done under these circumstances and as soon as practicable thereafter be presented to the Board of Public Utilities for approval. FISCAL IMPACT: Total cost for this work order is $70,353.50. Sufficient funds are available in the System Improvements Account No. 6130000-470635. Prepared by: Stephen H.
