Award a contract for the construction of the Gage/Waterman Water Supply Mains Interconnection Project — Bid No. RPU -7213 to the lowest responsive bidder, Hemet Manufacturing Co., Inc. dba Genesis Construction, of Hemet, California, in the amount of $3431777. BACKGROUND: The Gage/Waterman transmission pipelines serve important roles as major sources of supply to Riverside Public Utilities' (RPU's) water system. Each of these two pipelines deliver groundwater pumped from underground aquifers located in the San Bernardino area to Riverside. At Van Buren Street in the City of Grand Terrace, there is an existing interconnection between these two transmission pipelines, which provides added flexibility when the lower ends of these pipelines need to be shut down for operational or maintenance requirements. While most of the interconnection consists of a 24 -inch diameter pipeline, there is a 950 foot segment of the interconnection which is only 16- inches in diameter; undersized to meet operational needs. The scope of work will generally entail installation of approximately 950 linear feet of new 20 -inch CML &C Steel pipe along with all related valves, fittings and appurtenances parallel to the existing 16-- inch pipeline. A 15 -inch and a 20 -inch pipeline in parallel will deliver flows comparable to what a 24- inch pipeline will deliver. Bids were opened on January 9, 2014. The lowest responsive bid was submitted by Hemet Manufacturing Co., Inc. dba Genesis Construction (Genesis). Staff has reviewed all provided documentation and has determined that Genesis has met all of the requirements of the specifications.
