contingency amount not-to-exceed $136,000 (approximately 10 percent of the contract). 7. Authorize the transfer of $191,763 from the Bridge Approach Roadway Repairs, CIP No. 15524, to the Bridge Improvements at Various Locations, CIP No. 16514, for the Santa Rita Road Bridge at Arroyo Mocho approach slab work. 8. Authorize the transfer of $225,000 from the Santa Rita Road/Hopyard Road Piping Improvements, CIP No.18128, to the Bridge Improvements at Various Locations, CIP No. 16514, for water pipeline improvements required at the Santa Rita Road bridge. FINANCIAL STATEMENT Project funding totals $1 ,440,000, with $163,688 expended to date. The total estimated project expenditure is $1,856,763, leaving a project shortfall of $416,763. Staff recommends transferring $191,763 from the Bridge Approach Roadway Repairs, CIP No. 15524, to cover the project shortfall and provide the additional local match funding for the Santa Rita Road Bridge at Arroyo Mocho approach slab work. In addition, staff recommends transferring $225,000 from Santa Rita/Hopyard Piping Improvements, CIP 18128, to fund the required water pipeline work which is not an expense eligible for the federal grant. Funding includes $1,277,000 through a reimbursable federal grant and $354,763 of participating local funding, exceeding the required local match of 11.47 percent. Funding and anticipated project expenditures are detailed in Attachment 3. BACKGROUND The City's Bridge Maintenance Program (BMP) is updated through bi-annual bridge inspection reports performed by the state of California. Caltrans inspects all bridges located in the City of Pleasanton that are listed on the National Bridge Inventory (NBI). The BMP identified five bridges in need of preventative maintenance and the City applied for federal grant funding for the required work. In 2015, the City received approval from Caltrans, who administers the federal grant, to proceed with the design of bridge preventative maintenance. The City authorized BCA to complete the design work under an existing on-call contract. During the design, additional work was identified, and additional design and construction funds were approved by Caltrans in March 2017. During the final field review with Caltrans, Caltrans approved the addition of the Santa Rita Road Bridge at Arroyo Mocho approach slab work to address the differential movement that is a reoccurring issue at the bridge. Funding for design was approved in August 2017. Subsequently, Caltrans informed the City that the grant funding for project construction was deferred until FY 2019. DISCUSSION The project consists of performing major maintenance at the Santa Rita Road Bridge at Arroyo Mocho and preventative maintenance on four other bridges identified by the BMP (the four bridges are listed below). The Santa Rita Road bridge work includes construction of approach slabs and water line improvements. The installation of approach slabs will remove twenty feet of existing pavement on either side of the bridge and install a concrete slab that will move with the bridge, eliminating the reoccurring differential movement that can be felt as large bump by motorists traversing the bridge. The approach slab work will be phased by one traffic lane at a time, so the bridge remains in service with two lanes in each direction throughout the project. Nevertheless, Page 2 of 5
