RECOMMENDATION: That the Board of Public Utilities approve the capital expenditure of $1,673,000 for Work Order No. 1201978 which includes all design, construction, and paving costs for the Coonen Drive 8-Inch Distribution Main Replacement Project. BACKGROUND: The construction of the Coonen Drive 8-Inch Distribution Main Replacement Project is part of Riverside Public Utilities Department's (RPU) on-going water main replacement program to replace old and high priority leaky mains. The project area consists of existing 6-inch steel water mains that were installed in the 1950's and have experienced approximately 50 leaks, of which 21 have occurred in the last five years. The work will entail the construction of approximately 5,600 linear feet of eight-inch ductile iron pipe, 14 fire hydrants, 114 service tie-avers, and 11 system connections. The work identified will be constructed by RPU Water Division field forces. Once the new water pipelines are installed, RPU will be responsible for standard trench repaving per the Public Works standard. Near the end of pipeline construction, 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. FISCAL IMPACT: The total capital expenditure for Work Order No. 1201978 is estimated to be $1,673,000 which includes all design, construction, paving, contract administration and inspection costs necessary to perform the work, as summarized in the following table: Description Cost Percent of Total Design/Survey/Potholing $65,000 3.9% Construction (City Forces) $1,008,000 60.2% Construction Contingency $100,000 6.0% Paving Budget $500,040 29.9% Total $1,673,000 100% Sufficient funds are available in the Public Utilities' Water Main Replacement Account No. 6230000- 470707.
