CITY COUNCIL REGULAR MEETING AGENDA PACKET

Page 2 of 3 pumps to pull water from Zone 7's system and increase the pressure to the City's system- desired water-pressure setting. It will also be designed to meet the future peak demand of 5,200 gpm. As the existing site has minimal space, staff and the City’s design consultant, Woodard & Curran, Inc., developed plans and a request for proposals to solicit bids for purchasing a prefabricated (built off-site) booster station. The existing turnout, fluoride system, and traffic signal controller will remain in operation during construction. DISCUSSION The procurement of the pre-packaged booster station was done in conformance with the Uniform Public Construction Cost Accounting Act 22002.5, which allows flexibility from the conventional design, bid, and build process for public works projects necessary to maintain publicly owned water, power, or waste disposal systems. The consultant solicited proposals from several qualified pre-packaged booster stations through a Request for Proposal process outlining the station's requirements. Proposals were received in February 2024, ranging from $1.7 million - $1.8 million, exceeding the Engineer’s estimate of $850,000. After a detailed review, the project was value-engineered, which reduced the building size, modified the style of pumps, and clarified electrical equipment needs. A value-engineered proposal was developed, and three new proposals were received in August 2024, ranging from $1.17 million - $1.23 million. The City’s design consultants reviewed and approved the proposals, and confirmed the system would meet the City’s needs and that the design and pricing were valid. The designer reviewed their original engineer’s estimate and updated it to $1.2 million, with the earlier estimates not reflecting the market costs for the electrical and control equipment and the building structure. After the purchase order, City staff and the manufacturer will work through the specifics of the equipment and finishes. The City Engineer reviewed and confirmed that the solicitation and selection process conducted by the design consultant is in alignment with the City’s purchasing requirements and recommends awarding a purchase order in the amount of $1.17 million to Shape Incorporated of Pleasanton, California, for the Turnout No. 4 Pre-Packaged Booster Station Procurement, CIP No. 24181. In addition, staff recommends approving a 10 percent contingency (not to exceed $117,000) to cover potential City-requested changes and modifications during the shop drawing process. Engineer’s Estimate Shape Flow-Line Romtec $1,200,000 $1,170,000 $1,221,960 $1,228,875 The pre-packaged system will be housed in a 14-foot by 18-foot by 10-foot-tall fiberglass building (similar to the recycled water booster station in Ken Mercer Sports Park) mounted to a metal skid that allows for the building and equipment to be set in one piece. It will house three 50-horsepower pumps and motors that will deliver a firm capacity of 5,600 gpm and peak capacity of 7,000 gpm, meeting the City’s current and future demands. All electrical equipment, including PG&E metering, generator connections, and controls, are included. The installation of the pre-packaged booster station was included in the construction contract with JMB Page 175 of 658
