BACKGROUND
On April 22, 2025, the Board of Supervisors (BOS) authorized creation of the “Bale, Big Ranch, Lodi, Silverado Trail, and West Zinfandel Paving Project,” RDS 25-06 and a budget amendment of $50,000 to fund the design of the project.
The roads to be included in the project are as follows:
Bale Lane (0.70 miles) - All
Big Ranch Road (0.7 miles) - Oak Knoll Ave (east) to End
Lodi Lane (0.53 miles) - All
Silverado Trail (2.4 miles) - Zinfandel Lane to 6,000 feet south of the Caltrans SR 128
West Zinfandel Lane (0.56 miles) - All
Total miles: 4.9 miles
On May 6, 2025, the Board of Supervisors approved the plans and specifications and authorized to advertise for sealed bids and opening of the bids pursuant to Section 20150.8 of the Public Contract Code. On June 16, 2025, bids were received and opened. The bid results are attached for reference.
Staff recommends awarding the contract to the lowest responsive bidder, Team Ghilotti, Inc., of Petaluma, CA, for their base bid of $4,397,141. Team Ghilotti’s base bid is lower than the engineer’s estimate of $5,300,000. The total project cost, including design and engineering, construction, construction management, geotechnical services and contingency, is $6,046,147. The project will be funded by Measure-T.
Team Ghilotti, Inc. is not a local vendor however, the Public Contract Code requires that the construction contract be awarded to the lowest responsible and responsive bidder regardless of whether the low bidder is local or not. Staff reached out to the local construction contractor community by advertising the request for bids in the Napa Valley Register and the Solano-Napa Builder’s Exchange, and by posting on the County website. Staff also sent “Notices to Contractors” to the local construction community.
Requested Actions:
1. Award of the Construction Contract for the “Bale, Big Ranch, Lodi, Silverado Trail, and West Zinfandel Paving Project,” RDS 25-06 to Team Ghilotti, Inc., of Petaluma, California for their low base bid of $4,397,141 and authorization for the Chair to sign the construction contract;
