RPU-7298 ISSUE: The item for Board of Public Utilities consideration is approval of a contract award for the Gratton Booster Station Replacement Project, Bid No. RPU-7298. RECOMMENDATIONS: That the Board of Public Utilities: 1. Reject the bids submitted by Cora Constructors, Inc., and SCW Contracting, in the amounts of $888,572, and $900,000, respectively, as non-responsive; 2. Award a contract for the construction of the Gratton Booster Station Replacement Project, Bid No. RPU-7298 to the lowest responsive bidder, Hemet Manufacturing, Inc. dba Genesis Construction, of Hemet, California, in the amount of$942,777; and 3. Approve the capital expenditure of $1,311,100 for Work Order No. 1424014, which includes all design, construction, contract administration, inspection and construction contingency costs for the Grattan Booster Station Replacement Project—Bid No. RPU-7298. BACKGROUND: The 2013 Integrated Water Management Plan outlines improvements to the Gratton 1400 Pressure Zone which includes expansion of the existing Grafton Booster Station. The existing Grafton Booster Station was constructed in 1965 and is currently 49 years old and consists of two outside pumps and piping enclosed inside a chain link fence. Pump Nos. 1 and 2 were rebuilt in 2007 and 2006, respectively, and are currently in poor condition. The pumps, motors, piping and electrical systems have exceeded their useful life and need to be replaced. The proposed replacement booster station will be built approximately 4,000 feet northeast of the existing station within public right-of-way and adjacent to an existing Public Utilities easement along Grattan Avenue. The work for the replacement booster station will generally entail the construction of four (4) 40 HP pumps, electrical equipment, an electrical service, a control building, yard piping and construction of approximately 800 linear feet of 8-inch ductile iron pipe, including all other necessary fittings and appurtenances. Enclosing the equipment inside a control building will improve maintenance and security of the station and will mitigate noise. Following construction of the new station, the existing pump station will be abandoned and demolished. Bids were opened on December 30, 2014. Staff has determined that the two lowest bids, which were submitted by Cora Constructors, Inc., and SCW Contracting, were non-responsive due to the fact that the respective dollar amounts listed for"Item No. 1 — Mobilization..." were in excess of the stipulated five- percent cap. Consequently, the lowest responsive bid was submitted by Hemet Manufacturing, Inc. dba Genesis Construction. Staff has reviewed all provided documentation and has determined that Hemet Manufacturing, Inc. dba Genesis Construction has met all of the requirements of the specifications.
