The project will: construct a bulb out bioretention planter and install a Rectangular Rapid Flashing Beacon at Amador Valley Boulevard and Wildwood Road; modify the traffic signal, construct new curb ramps, and modify medians at Amador Valley Boulevard and Stagecoach Road; and will convert the Amador Valley Boulevard median irrigation to recycled water east of Stagecoach Road. STAFF RECOMMENDATION: Adopt the Resolution Approving the Plans and Specifications and Awarding a Contract to Golden Bay Construction, Inc., for Amador Valley Boulevard - Wildwood Road and Stagecoach Road Intersections Improvements Project No. ST0317. FINANCIAL IMPACT: As approved in the 2018-2023 Capital Improvement Program, the total remaining budget for the Amador Valley Boulevard – Wildwood Road and Stagecoach Road Intersections Improvements is $859,971.86. The lowest responsive bid for construction was $636,761.70. A construction contingency of $75,000 is requested for unforeseen construction issues, bringing the total potential construction cost to $711,761.70. Sufficient funding is available in the project budget to cover th e construction contract costs. DESCRIPTION: The Five-Year Capital Improvement Program (CIP), adopted by City Council, includes Amador Valley Boulevard - Wildwood Road and Stagecoach Road Intersections Improvements, CIP No. ST0317 (Attachment 1). The project will construct a landscaped Page 2 of 3 bioretention planter and bulb out and will install pedestrian activated Rectangular Rapid Flashing Beacons (flashing pedestrian warning lights) at the Amador Valley Boulevard and Wildwood Road intersection. The project will also modify traffic signal infrastructure and signal timing, for safer pedestrian crossing, construct new cub ramps, and modify the medians, roadway striping, and signs at the Stagecoach Road intersection. The project will also convert the Amador Valley Boulevard median irrigation from potable water to recycled water. The plans and specifications were completed and advertised for bids in March 2019. A total of two sealed bids were received on April 2, 2019. A summary of the bids is provided as Attachment 2. The low bid of $636,761.70 was submitted by Golden Bay Construction Inc. The low bid contained an arithmetic error between an item unit cost and the mathematical sum, which subsequently decreased the total base bid price by $40. The Public Contract Code and the City’s bid documents define this as a “minor bid irregularity,” and authorize the City to waive this irregularity and proceed with the award of the contract. Staff has reviewed the bid results and bidder qualification statements, checked references and necessary licenses, and recommends that the City Council adopt the Resolution (Attachment 3), awarding the project construction contract to Golden Bay Construction Inc, as the lowest responsive bidder. To facilitate the approval of contract change orders and to avoid construction delay, it is requested that the City Manager be authorized to approve change orders up to the contingency amount of $75,000. The Resolution will authorize this change as it relates to this project. Staff expects the project to begin in early June 2019 and anticipates completion by the end of September 2019. To minimize impact to school-related vehicular, bicycle, and pedestrian traffic, the contract specifications require the contractor to diligently pursue all work items prior to August 10. Work occurring after August 10 shall not result in closure of more than one crosswalk at a time. This project is exempt under Section 15301 (Existing Facilities) of the CEQA Guidelines. NOTICING REQUIREMENTS/PUBLIC OUTREACH: Strategy 3: Pursue efforts to help strengthen the City’s infrastructure and technology. Strategic Objective 3b: Continue to embrace technology to improve traffic street and engineering infrastructure. NOTICING REQUIREMENTS/PUBLIC OUTREACH: A copy of this staff report was sent to Golden Bay Construction, Inc. and to the Alameda County Transportation Commission, Independent Watchdog Committee.
