IN THE AMOUNT OF <br />$1,048,777 FOR THE PURI COURT STORM DRAIN IMPROVEMENTS PROJECT, <br />CIP NO. 25415, AUTHORIZE THE CITY MANAGER, OR DESIGNEE, TO <br />APPROVE AND EXECUTE CONTRACT CHANGE ORDERS FOR A PROJECT <br />CONTINGENCY AMOUNT NOT TO EXCEED $157,317 <br /> <br />SUMMARY <br />The Puri Court Storm Drain Improvements project will replace existing storm drain pipe of <br />various sizes with a 48-inch reinforced concrete pipe (RCP) and a custom-sized box culvert to <br />improve flow capacity and mitigate future flood risks. A competitive bidding process was <br />followed in accordance with the City's Procurement and Contracting Procedures. Nine bids <br />were received, with DPI, Inc. as the lowest responsive and responsible bid of $1.048,077. Staff <br />recommends the City Council award the construction contract to the lowest responsible bidder, <br />DPI, Inc. in the amount of $1,206,094, inclusive of a 15 percent contract contingency of <br />$157,317 for unexpected and unforeseen conditions and changes. <br /> <br />RECOMMENDATION <br />1. Award a construction contract to DPI, Inc. of Livermore, CA, in the amount of <br />$1,048,777 for the Puri Court Storm Drain Improvements Project, CIP No. 25415. <br />2. Authorize the City Manager to enter into the construction contract with DPI, Inc. <br />3. Authorize the Director of Public Works, or authorized staff, to approve and execute <br />contract change orders for a project contingency amount not to exceed $157,317 <br />(approximately 15 percent of the contract). <br /> <br /> <br />BACKGROUND <br />Severe winter storms from December 2022 to March 2023 caused damage throughout <br />Pleasanton. These weather events resulted in risks to the health, safety, and welfare of people <br />and property due to flooding, downed trees, loss of power, and property damage. The Puri <br />Court area (location map provided as Attachment 3) experienced severe flood damage during <br />the 2023 storm event. Previously, in 2017, properties on Puri Court also experienced flooding. <br /> <br />The existing main storm drain line that runs through Puri Court conveys offsite drainage from <br />undeveloped areas west of Foothill Road and tributary areas adjacent to Puri Court. The <br />existing storm drain pipe in Puri Court varies between 24-30 inches in diameter, and the <br />existing pipe sizes were determined to be undersized for carrying the required flow. The <br />proposed project, designed to current standards, will replace the existing pipe with a 48-inch <br />reinforced concrete pipe and a custom-sized box culvert (5 feet by 3 feet) to improve flow <br />capacity and mitigate future flood risks. <br /> <br />Page 176 of 223
