W A T E R 1 E N E R G Y 1 t 1 F E PUBLIC RIVERSIDE PUBLIC UTILITIES Board Memorandum BOARD OF PUBLIC UTILITIES DATE: OCTOBER 3. 2014 ITEM NO: 10 SUBJECT: CONSTRUCTION OF THE JASMINE AND COLUMBUS 12 -INCH WATER DISTRIBUTION MAIN REPLACEMENT PROJECT — WORK ORDER NO. 1507007 ISSUE: The item for Board of Public Utilities consideration is approval of the capital expenditure in the amount of $679,000 to construct the Jasmine and Columbus 12 -Inch Water Distribution Main Replacement Project. RECOMMENDATION: That the Board of Public Utilities approve the capital expenditure of $679,000 for Work Order No. 1507007, which includes all design, construction, paving, contract administration, inspection and construction contingency costs for the Jasmine and Columbus 12 -Inch Water Distribution Main Replacement Project. BACKGROUND: The construction of the Jasmine and Columbus 12 -Inch Water Distribution Main Replacement Project is part of Riverside Public Utilities' (RPU) on -going water main replacement program to replace old, undersized and high priority leaky mains. The project consists of replacing existing 4 -inch asbestos cement (AC) and 6 -inch cast iron (CI) pipe waterlines that were installed in 1953 and 1957, respectively. These pipelines are inadequately sized to support the fire flow demand required per the City's General Plan Industrial Land Use designation. This work will also allow RPU to abandon an existing 300 foot long segment of 8 -inch 1973 AC pipe located in Ordway Street. The public street right -of -way for Ordway Street at this location will be vacated as part of a current development project. The developer will be contributing $25,000 to RPU toward their share of the pipeline relocation costs. The work will generally entail the construction of approximately 1,300 linear feet of 12 -inch ductile iron pipe within Jasmine Street and Columbus Avenue, 60 linear feet of 24 -inch steel casing installed via bore and jack beneath an existing railroad track, 16 water services, 4 fire hydrants and 3 system connections, along with all necessary fittings and appurtenances. The trench resurfacing is also included, per Public Works Department (PW) paving standards. Once the water pipeline design is complete, it is anticipated that City Forces will construct the water pipeline. Staff will utilize RPU's contractor panel to construct the 24 -inch steel casing and trench resurfacing. If City Forces are not able to complete the pipeline work based on their availability and other priorities at that time, the pipeline work will also be constructed by the contractor's panel. Budgetary estimates for the water pipeline construction, bore and jack and paving work are included in this authorization. Staff will coordinate with PW regarding the allowable working hours and traffic control for this project. It is anticipated that work will be permitted during normal daytime hours. Other than routine service tie - overs, no service disruptions are anticipated to complete the work of this project.
