RECOMMENDATION: That the Board of Public Utilities approve the estimated capital expenditure of $923,800 to relocate overhead and underground electrical equipment and structures (located at Iowa Avenue and Citrus Street)to accommodate new bridge construction for the Iowa Avenue Grade Separation Project. BACKGROUND: The electric system in this area is primarily overhead and includes both 12 kV distribution facilities and 69 kV transmission facilities. The construction of the Iowa Avenue bridge over the railroad tracks (grade separation) necessitates the removal of most of the overhead facilities and conversion to underground. A steel foundation pole will be installed to accommodate the 69 kV transmission lines, and a steel casing will be installed under the railroad tracks for current and future 12 kV distribution facilities. Pad-mounted devices will be installed to replace the overhead utilities that will be removed. The electrical engineering was performed by Riverside Public Utilities (RPU). All civil work including trenching, conduits and other infrastructure work will be performed by a contractor through the competitive bid process. Electrical work will be performed by RPU field forces. FISCAL IMPACT: The capital expenditure for the project is estimated to be $923,800, of which $256,360 will be reimbursed to the City by AT&T for proposed joint trench facilities, leaving a net cost to RPU of $667,440. This includes all construction, construction management, inspection and design, and contingencies as summarized in the following table: % of Total Design, Construction Management, Inspection $72,000 8% Construction-RPU Electrical Work$ Materials $226,500 25% Construction-Electric Conduit & Structures $580,300 62% Contingency $45,300 5% Subtotal. $923,800 100% Funds are budgeted and available for this project in the Cable Replacement Account No. 6130000- 470619.
