W A T E R ENERGY LIFE WI Wig PUBLIC UTILITIES RIVERSIDE PUBLIC UTILITIES Board Memorandum BOARD OF PUBLIC UTILITIES DATE: OCTOBER 3, 2014 ITEM NO: 11 SUBJECT: CONSTRUCTION OF THE WOHLSTETTER AND COOK WATER MAIN REPLACEMENT PROJECT — WORK ORDER NO. 1422199 ISSUE: The item for Board of Public Utilities consideration is approval of the capital expenditure in the amount of $1,136,000 to construct the Wohlstetter and Cook Water Main Replacement Project. RECOMMENDATION: That the Board of Public Utilities approve the capital expenditure of $1,136,000 for Work Order No. 1422199, which includes all design, construction, paving, contract administration, inspection and construction contingency costs for the Wohlstetter and Cook Water Main Replacement Project. BACKGROUND: The construction of the Wohlstetter and Cook Water Main Replacement Project is part of Riverside Public Utilities' (RPU) on -going water main replacement program to replace old and high priority, leaky mains. The project area consists of existing 4 -inch and 6 -inch asbestos cement pipe and 6 -inch and 8- inch steel pipe water mains that were installed between 1947 and 1965 and have recently experienced numerous Teaks requiring repairs. Based on their leak history, these water pipelines have been identified as high priorities for replacement. The work will entail the construction of approximately 3,790 linear feet of 8 -inch ductile iron pipe, nine fire hydrants, 61 service tie -overs and ten system connections. The work identified will be constructed by the Water Division's field forces. Other than routine service tie - overs, this project is not expected to disrupt service to RPU water customers. Once the new water pipelines are installed, RPU will be responsible for standard trench repaving per the Public Works Department standard. Staff will solicit paving bids for paving the trench area from RPU's Paving Contractor Panel. A budgetary estimate for the paving work has been included in this authorization. The work is scheduled to occur during daytime hours. A portion of the work is located in the vicinity of the Foothill Elementary and Wells Middle Schools. Work affecting the schools will be coordinated with the school's respective bell schedules to minimize impacts.
