Reconstruction involves the removal of the entire existing <br />pavement section, strengthening the road base by mixing cement into the existing subgrade, <br />recompacting the subgrade to remove voids resulting from the cement mixing and replacing <br />the entire thickness of pavement. <br />This project will incorporate recycled rubber asphalt concrete in the rehabilitation of certain <br />streets. The California Department of Resources Recycling and Recovery (CalRecycle) will <br />reimburse the City based on the differential cost between the actual conventional asphalt and <br />the rubberized asphalt costs through a grant. Rubberized asphalt is made by blending <br />ground-up recycled tires with asphalt to produce a binder which is then mixed with <br />conventional aggregate materials. The use of recycled tires provides an opportunity to reduce <br />the quantity of non-biodegradable byproducts from polluting the environment and aligns with <br />the City’s sustainability efforts under the Climate Action Plan. Rubberized asphalt concrete is <br />a new material for City streets that will be utilized on Teagarden Street as a pilot project and <br />will divert approximately 1,334 tires from the waste stream. If the pavement performs as <br />expected, the material may be used on future projects. <br />Overlay or reconstruction of streets triggers requirements to upgrade all deficient curb ramps <br />adjacent to the work. As part of this project and in compliance with the Americans with <br />Disabilities Act (ADA), 29 curb ramps and associated upgrades will be constructed in Phase <br />1. The project will also incorporate relevant portions of the City’s Bicycle and Pedestrian <br />Master Plan. <br />This project also includes the installation of new speed humps on Castro Street and 138th <br />Avenue that were requested by residents that participated in the 2016-17 Neighborhood <br />Traffic Calming Program. Additionally, Phase 1 of the project involves restriping of San <br />Leandro Boulevard from the City’s north limit to north of San Leandro Creek to be one lane in <br />each direction with a two-way left turn lane, bike lanes, and safety improvements at the Best <br />Avenue intersection. All of this work is expected to be completed in 60 working days. <br />Analysis <br />Bids were opened on June 26, 2017. The one bid received was $3,048,462 from DeSilva <br />Gates Construction, L.P. The pre-bid engineer’s estimate for construction was $2,620,569. <br />Staff contacted other firms that attended the pre-bid conference but elected not to submit bids <br />and learned that they chose not to bid due to an already heavy work load. <br />The bidder does not have an office in San Leandro that would qualify them as a local <br />business per the Local Inclusion Policy Ordinance. Also, the bidder has not met the Local <br />Business Participation Goal of 25% by subcontracting with San Leandro businesses for 25% <br />of the contract value. The bidder had one local subcontractor, St. Francis Electric, whose <br />subcontract for $4,500 represents 0.15% of the total contract value. However, the bidder <br />provided documentation that demonstrated completion of the required good faith efforts to <br />meet the local business participation goal. <br />Page 2 City of San Leandro Printed on 7/11/2017 <br />456
