Approve the capital expenditure of $973,500 for Work Order No. 1415931, which includes all design, construction, contract administration, inspection and construction contingency costs for the California and Monroe Water Main Replacement Project — Bid No. RPU -7286. BACKGROUND: The construction of the California and Monroe 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 6 -inch cast iron water mains that were installed between 1956 and 1957 and have required numerous repairs due to leaks over the past several years. Based on their leak history and age, these water pipelines have been identified as high priorities for replacement to increase system reliability. Riverside County Flood Control and Water Conservation District ( RCFCWC) will be undertaking a major overhaul of the Monroe Storm Channel which is located along Monroe Street in the vicinity of this project. The storm channel improvements are scheduled to begin in early summer of 2015. The Riverside Public Works Department (PW) is planning to follow the storm channel improvements with new asphalt pavement along Monroe Street as part of their arterial roadway resurfacing program. Staff has coordinated with RCRCWC and PW, and the water pipeline replacement work has been arranged to take place in advance of the storm channel and pavement improvements. The water pipeline work will generally entail the construction of approximately 2,080 linear feet of 12 -inch ductile iron pipe, 370 linear feet of 8 -inch ductile iron pipe, 210 linear feet of 4 -inch ductile iron pipe, 17 water services, 8 fire hydrants and 11 system connections, along with all necessary fittings and appurtenances. The trench resurfacing is also included, per PW paving standards. Subsequent to the pipeline work, PW is scheduled to complete the final surface paving as part of their roadway resurfacing improvements on Monroe Street. Staff has coordinated with PW regarding the allowable working hours and traffic control for this project. The work is scheduled to occur during normal daytime hours.
