BACKGROUND: On Saturday July 16, 2011, a 1976 high voltage cable failed on Arlington Avenue, westerly of Anna Street, interrupting service to 34 customers. During restoration switching, City crews found another section of failed high voltage cable on Anna Street and Cimarron Road. northerly of Arlington Avenue. City crews were unable to remove the existing Cable in Conduit (CIC); however, they were able to install a temporary cable to restore service to the affected customers. Emergency Work Order No. 1202225 was issued to contract crews from International Line Builders, a member of the Contractors' Panel for Energy Delivery Work, to trench and install 350 feet of conduit, and a primary structure to temporarily restore the electrical system. The work started on July 20, 2011 and was completed on July 30, 2011. City crews installed all the electrical components and removed the temporary cable. The Public Works Department had recently completed a pavement rehabilitation project in the area and, therefore, permitted only the minimum amount of emergency work necessary for public safety. Permanent repairs were deferred for three years to comply with Public Works' policy and the necessary work will now be undertaken. Work Order No. 1322051 includes: • Installation of one 3 foot x 5 foot Pull Box • Installation of 1,315 feet of 4-inchconduit. • Replacement of 1315 feet of #2AL CIC HMPE cable with new 1/OAL XLPE cable in 4-inch conduit. • Approximately 44,095 square feet of Type 1 asphalt slurry pavement Engineering has been completed by Riverside Public Utilities (RPU) staff. All construction work including trenching, conduits, and other infrastructure work will be performed by contract crews from the Contractor's panel. Directional boring will be used, where possible, to minimize cost and street repairs. All electrical work including cable installation, splicing and terminations will be done by RPU crews.
