RECOMMENDATIONS: That the Board of Public Utilities: Approve the capital expenditure of $535,000 for Work Order No. 1227664, which includes all design, construction, contract administration, inspection and construction contingency costs for the Water Transmission Main Valve Replacement Project — Phase III, Bid No. RPU -7212; and 2. Award a contract for the construction of the Water Transmission Main Valve Replacement Project — Phase III, Bid No. RPU -7212 to the lowest responsive bidder, Trautwein Construction, of Riverside, California, in the amount of $368,056. BACKGROUND: The Riverside Public Utilities (RPU) uses transmission mains to move water efficiently throughout its service area. In early 2011, staff identified a list of critical transmission valves to be replaced as part of the ongoing asset management program, On January 20, 2012, the Board of Public Utilities (Board) awarded a construction contract to replace five transmission main valves that were identified to be in immediate need of replacement to enhance system reliability and operational effectiveness. The Board awarded a subsequent construction contract on May 3, 2013 to replace three additional inoperable transmission main valves. The next set of valves to be replaced based on priority is located on 24 -inch, 36 -inch and 48 -inch transmission pipeline segments throughout RPU °s service area (Attachment 1). These three isolation valves are unreliable and they impact staffs ability to operate the system efficiently and effectively. Upon investigation, these valves have been determined non - repairable and were listed as high priority valves to be replaced. Staff is continuing the process of evaluating other transmission main valves to determine their status and priority for replacement. Work associated with additional valves will be presented to the Board for future approval to repair or replace as appropriate. The work of the subject project will generally entail removal and replacement of three transmission main valves with new 24 -inch, 36 -inch and 48 -inch valves, along with all other related fittings, appurtenances and pavement restoration. The system shutdowns needed for this work will be carefully scheduled and coordinated by staff to minimize disruptions to the system, Bids were opened on December 30, 2013. The lowest responsive bid was submitted by Trautwein Construction. Staff has reviewed all provided documentation and has determined that Trautwein Construction has met all of the requirements of the specifications.
