BACKGROUND <br /> The 2017/18 Capital Improvement Program budgeted $200,000 in CIP No. 17135, Bi- <br /> Annual Fire Hydrant Laterals and Various Control Valves Replacement Project. The <br /> project justification states the funding is needed to repair fire hydrants and fire hydrant <br /> laterals that are damaged or are otherwise identified as needing repair over the two- <br /> year budget period. However, there has been a significant and unusual amount of earth <br /> movement in the Hacienda Business Park, particularly along West Las Positas <br /> Boulevard. This has caused a number of fire hydrant laterals to break, resulting in the <br /> hydrants being removed from service. This project replaced 19 fire hydrant laterals, <br /> including some which were pre-emptively replaced before breaking. In addition, a <br /> broken water main at the Stoneridge and Tassajara bridge crossing was replaced with <br /> piping that will accommodate future earth movement. <br /> The second component of this project involved replacing control valves and other <br /> appurtenances, such as end-of-pipe blow-off valves used for flushing to ensure water <br /> quality. These items are being replaced as part of a preventative maintenance program <br /> in areas where resurfacing and slurry seal projects are planned. Many of the pipes and <br /> valves were old and corroded. The replacement was done before the planned roadwork, <br /> not only to avoid needing to dig into a newly paved street, but also to avoid breakage <br /> that could occur while the roadwork was being accomplished. The specific locations <br /> were selected from the priority list developed by the Utilities Division, in conjunction with <br /> a list of roadways identified for the 2018 resurfacing and slurry seal projects. <br /> On February 20, 2018, City Council awarded the contract to the lowest responsible <br /> bidder, Northern Underground Construction, Inc., in the amount of$850,735. Council <br /> authorized the Director of Engineering to approve change orders up to the project <br /> contingency amount of$127,000. On October 30, 2018, the City Manager authorized <br /> the project contingency to be increased by $14,756, for a total of$141,756 to cover <br /> additional emergency work performed under the contract. The project has since been <br /> completed and is ready for acceptance. <br /> DISCUSSION <br /> Northern Underground Construction, Inc. performed emergency and additional work <br /> outside of the scope of the project in support of our Operations Service Department. In <br /> the Valley Trails subdivision, blow off devices were replaced to allow for additional <br /> flushing, addressing a water quality issue. A broken sewer lateral was encountered on <br /> First Street during paving and needed to be repaired to complete the paving. On the <br /> recycled water line from Livermore, a leak in the old CWR line was found and repaired. <br /> These additional work items ended up exceeding the project contingency and required <br /> an increase in the contingency amount. <br /> Budget <br /> The final project funding and expenditures are summarized in Attachment 1, indicating a <br /> total project expenditure of$997,819 and total funding of$977,835, leaving a shortfall of <br /> $19,984. Funding was provided from the Bi-Annual Water Tank Corrosion Repairs; <br /> Page 2 of 3 <br />
