W A T E R E N E R G Y t i RIVERSIDE PUBLIC UTILITIES Board Memorandum PUBLIC UTJLITIES BOARD OF PUBLIC UTILITIES DATE: June 15, 2012 ITEM NO: 3 SUBJECT: ELECTRICAL CABLE REPLACEMENT AT FIESTA AVENUE,IMPERIAL STREET AND GOODVIEW AVENUE -WORK ORDER NO. 1217690 ISSUE. That the Board of Public Utilities consider approval of Work Order No. 1217690. RECOMMENDATION: That the Board of Public Utilities approve the estimated capital expenditure of$284,400 for Work Order No. 1217690 to replace failed or defective 12kV distribution cable on Fiesta Avenue, Imperial Street and Goodview Avenue. BACKGROUND; On August 27, 2011, there was a 12kV cable failure in the Fiesta - Goodview Avenues area of the City. Riverside Public Utility(RPU) crews were able to restore service through switching the load to an alternate, adjacent circuit pending replacement of the failed cable. Subsequent investigation determined that the failed cable caused significant damage to the conduit, requiring its replacement as well. Also,the adjoining cables in that immediate area are identified to be replaced through the cable replacement program. Engineering has now been completed by RPU staff. The Project includes: • Installation of one S X 5' pull box • Installation of 3,897' of conduit • Replacement of 1200' of#2AL C[C HMPE cable with new 114AL XLPE cable in conduit • Approximately 36,000 sq. ft. of pavement grind and asphalt overlay • Approximately 103,544 sq, ft. of rubberized slurry All construction work including trenching,conduits,and other infrastructure work will be performed by contract crews from the Electric Contractors'Panel. Directional boring maybe used,if possible,to reduce the amount of street repairs needed. All electrical work including cable installation,splicing and terminationswil[be done performed by RPU field forces. The Project also includes deferred paving on Collingwood Drive,Amanda Court and Lydia Avenue due to a previous cable failure and repairs that occurred in September 2011. Paving for this work was deferred to help minimize the impact on focal residents and to allow for normal bidding processes to be used. Streets in this area were completely renovated by Public Works within the last three years. FISCAL IMPACT: The capital expenditure for the project is estimated to be $280,000 and is broken out as follows:
