Approve additional capital expenditure in the amount of $85,000 for Work Order No. 1501824 for a revised total of $1,349,000. BACKGROUND: The Board of Public Utilities approved Work Order No. 1501824 on September 18, 2015, in the amount of $1,264,000 for the Plaza Substation 4kV to 12kV Circuit 454 Conversion Project. At the time of approval, the conversion work was anticipated to be performed by RPU field forces. However, due to an increase in development projects and emergency work, staff determined that contracting for the work would avoid further construction delays. This work is identified as part of the Electric System Master Plan which recommends the conversion of all remaining 4 kV to 12 kV distribution circuits to improve system capacity and reliability. The work will upgrade electrical distribution facilities west of Magnolia Avenue in the region between Linwood Place and Tequesquite Avenue. Replacement of aged overhead infrastructure is identified as part of the Utility 2.0 Electrical Infrastructure Road Map. The scope of work will replace 41 wooden poles, 43 transformers, five pole switches, 20,000 circuit feet of primary wires, 6,500 circuit feet of secondary cables and related overhead distribution facilities. The scope also includes removal of the existing aged facilities. Outage notifications will be issued prior to any work, and any resulting electric service disruptions will be coordinated with customers to minimize any impact.
