HomeMy WebLinkAboutItem 4.06 Contract Award for the Tassajara Road Overlay Projector 19 82 /ii � 111 DATE: TO: FROM: SUBJECT STAFF REPORT CITY COUNCIL June 21, 2016 Honorable Mayor and City Councilmembers CITY CLERK File #600 -35 Christopher L. Foss, City Manager " Award of Contract to O'Grady Paving Inc., Approval of Plans and Specifications, and Waive Minor Bid Irregularity for the Tassajara Road Overlay Project, Project No. ST5016. Prepared by Michael eoitnott, Senior Civil Engineer EXECUTIVE SUMMARY: The 2016 Annual Street Overlay Program is included in the Capital Improvement Program adopted by the City Council. This year's project will provide an asphalt concrete overlay of Tassajara Road from the 1 -580 off -ramp to North Dublin Ranch Drive. The project includes the installation of an asphalt rubber overlay, repair of failed segments of the roadway, installation of new traffic signal detection loops and pavement markings, and modifications to comply with Americans With Disabilities Act. FINANCIAL IMPACT: The estimated total cost of the improvement project is approximately $2.33 million, which requires an additional budget appropriation of $90,000 from the Noise Mitigation Fund and $181,000 from the Gas Tax Fund, for a total appropriation of $271,000 to the 2016 Annual Street Overlay Program (CIP No. ST5016). The amount of the lowest responsive bid was $1,822,890.65. A 10% construction contingency in the amount of $182,000.00 is requested for unforeseen construction issues, bringing the total construction contract cost to $2,004,890.65. RECOMMENDATION: Staff recommends that the City Council adopt the Resolution Approving the Plans and Specifications, Waiving a Minor Bid Irregularity, and Awarding a Contract for Project No. ST5016 to O'Grady Paving, Inc. for the Tassajara Road Overlay Project; and approve the Budget Change. �ubmitteb By Public Works Director '\ Reviewed By Assistant City Manager Page 1 of 3 ITEM NO. 4.6 DESCRIPTION: The Tassajara Road Overlay Project includes the design and construction of a rubberized asphalt overlay of Tassajara Road from the 1 -580 off -ramp to North Dublin Ranch Road. This segment of roadway is a heavily used arterial road and is starting to show signs of asphalt rutting and failure. Tassajara Road is an ideal candidate for an overlay, before the road deteriorates further and becomes more costly to repair. An asphalt rubber overlay provides a quieter driving surface, is more flexible, and will increase the durability of the roadway. The construction was planned by staff to be performed during summer 2016 while the culvert at the north end of Tassajara Road is being replaced and the road is closed to traffic coming from and going into Contra Costa County. The reduction of pass- through traffic results in less traffic for the overlay contractor to contend with, and shorter construction - related delays to Dublin residents. The plans and specifications for the Tassajara Road Overlay Project were completed and the project was advertised for bids in the beginning of May 2016. The project improvements will include but are not limited to: asphalt overlay, repairs to failing pavement, pavement markings; traffic signal loop detectors, and curb ramp upgrades to comply with Americans with Disabilities Act (ADA). This project is exempt under Section 15301 (Existing Facilities) of the CEQA Guidelines. Due to daytime traffic congestion and the Caltrans permit requirements for the work near 1 -580, the project will include night work. The limits of night work will be from 1 -580 to approximately 400 feet north of the Dublin Boulevard intersection, as shown on the Location Map (Attachment 1). The night work activities will include asphalt paving, grinding, installation of traffic loop detectors, and adjusting utilities to grade. The remainder of the work will be performed during the day. A total of three sealed bids were received on June 2, 2016, ranging from $1,822,890.65 to $2,031,179.00 (bid summary provided as Attachment 2). The low bid of $1,822,890.65 was submitted by O'Grady Paving Inc. This bid contained an arithmetic error between an item unit cost for traffic loop detectors and the extension of that unit cost, which subsequently adjusted the total base bid price by $4,450. However, the Public Contract Code requirements 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, checked references and necessary licenses, and recommends that the City Council adopt the Resolution (Attachment 3) awarding the contract to O'Grady Paving 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 $182,000.00 The Resolution will authorize this change as it relates to this Project. Staff expects the project to begin in July and anticipates completion of the majority of the improvements by mid - September 2016. Project Budget: The total estimated cost for the improvement project is approximately $2.33 million. The approved budget for the 2016 Annual Street Overlay Program is $665,233. In order to complete this project, which is larger than past annual overlay projects, and to take advantage of lower traffic volumes due to the road closure to the north, staff recommends using the budget from the Page 2 of 3 2016 Annual Slurry Seal Program (ST5116) and the remaining available budget from both the 2015 Annual Slurry Seal Program (ST5115) and the 2015 Annual Street Overlay (ST5015) to fund this year's overlay. Staff also recommends shifting $86,000 of CalRecycle grant funding from the Dougherty Road Improvements project (ST0911) to the annual overlay because the grant funds must be expended by April 1, 2017, which likely would not happen on Dougherty Road based on the project schedule. In addition to using available budgets from the other pavement maintenance projects and the CalRecycle grant, Staff recommends a budget appropriation of $90,000 from the Noise Mitigation Fund and $181,000 from the Gas Tax Fund for a total appropriation of $271,000 to the 2016 Annual Street Overlay Program (CIP No. ST5016). A summary of the proposed project adjustments on the Budget Change Form (Attachment 4) is shown as follows: ST5015 Annual Street Overlay Project 2015 $ 502,000 ST5115 Annual Slurry Seal Project 2015 $ 121,000 ST5116 Annual Slurry Seal Project 2016 $ 684,000 CalRecycle Grant for Rubberized Asphalt $ 86,000 ST5016 Annual Street Overlay Project 2016 $ 665,233 Noise Mitigation Fund Appropriation $ 90,000 Gas Tax Fund Appropriation $ 181,000 ST5016 Project Total Funding $2,329,233 NOTICING REQUIREMENTS /PUBLIC OUTREACH: As required by the specification, the Contractor will notify all affected residents and businesses one week as well as 24 hours in advance of the overlay improvements.
