RECOMMENDATION: That the Board of Public Utilities approve the capital expenditure of $2,150,000 for Work Order No. 1308883 which includes all design, construction, paving, contract administration and construction contingency costs for the Park Avenue and Grove Avenue Water Main Replacement Project. BACKGROUND: The construction of the Park Avenue and Grove Avenue 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 replacement project was originally scheduled to occur in the Fiscal Year 2014- 15. However, the Public Works Department (PW) is scheduled to pave several streets in the area and this project was shifted in priority to reduce overall costs. The project area consists of existing 4 -inch and 6 -inch water mains that were installed between 1928 and 1946 and have experienced several leaks. The work will entail the construction of approximately 7,600 linear feet of 8 -inch ductile iron pipe, 128 service tie - overs, 22 fire hydrants, and 20 system connections. The work identified will be constructed by the Water Division's field forces. Once the new water pipelines are installed, RPU will be responsible for standard trench repaving in accordance with PW's paving standard and based on coordination with PW staff. Staff will solicit paving bids for paving the trench area from RPU's Paving Contractor Panel- A budgetary estimate for the trench resurfacing work has been included in this authorization. The final asphalt pavement improvements will occur as part of PW's upcoming street improvement project.
