RECOMMENDATION: That the Board of Public Utilities approve the estimated capital expenditure of $75,171.21 for Emergency Work Order No. 1316577 in accordance with Article XII, section 1202(2) (b) for the City of Riverside Charter. BACKGROUND: On Tuesday January 15, 2013, a section of 12 kV Cable in Conduit (CIC) faulted on Copenhagen Drive westerly of Monroe Avenue (Attachment 1) interrupting service to approximately 70 customers. During restoration switching, City crews found another section of faulted 12 kV CIC on Amsterdam Drive westerly of Monroe Avenue. 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 Asplundh Construction, a member of the Contractors' Panel for Energy Delivery Work, were immediately directed to install 729 feet of trenching and 1,023 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 January 17, 2013, and was completed on January 31, 2013. The contractor's cost, including weekend work totaled $62,791.27. City crews installed all the electrical cables and accessories with multiple crews for a total amount of$12,379.94. 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 Work Order No. 1316577 is $75,171.21. Sufficient funds are available in the Cable Replacement Account No. 6130000-470635.
