RECOMMENDATION: That the Board of Public Utilities approve Work Order No. 1831543 in the amount of $71,803 and Work Order No. 1831515 in the amount of $8,980 for a total amount of $80,783, in accordance with the City of Riverside Charter Article XII, section 1202(b)(2), for emergency work completed due to the primary cable burn-up on Merlin Drive and Lancelot Court. BACKGROUND: On Wednesday May 30, 2018, a section of 12kV cable -in -conduit (CIC) faulted on Merlin Drive easterly of Lancelot Court (see project site map) interrupting service to approximately nine (9) customers. CIC was a common industry practice developed in the late 1960's. As part of the manufacturing process for CIC, cable was pre-installed in the conduit before the CIC was 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 had to install a generator to maintain service and design a more permanent installation. When electric service is provided to customers via generator, there are high voltage facilities installed above ground in a temporary fashion. Exposed, high voltage facilities pose a risk to the public therefore exposure should be limited. As such, staff began repairs immediately under City of Riverside Charter Article XII, section 1202(b)(2) which allows work to be done without prior approval if there is an urgent necessity to preserve life, health or property. As soon as practically thereafter, the matter shall be presented to the Board of Public Utilities. Members of the Contractors' Panel for Energy Delivery work were contacted for immediate availability and Doty Bros. was the first responder. Subsequently, contract crews from Doty Bros. were immediately directed to install 520 feet of trenching and 520 feet of conduit to restore the electrical system to normal operating condition. Work started on June 1, 2018, and was completed on June 8, 2018. The contractor's cost, including weekend work totaling $71,803, including RPU Inspection. City crews installed all the electrical cables and accessories with multiple crews for a total amount of $8,980.
