BACKGROUND
On February 6, 2024, the Board of Supervisors (Board) authorized creation of the “North County Crossroads Paving project,” RDS 24-08 and a budget amendment of $600,000 to fund the design of the project. On February 27, 2024, the Board authorized a professional services agreement with GHD INC. for design and construction administrations services. The project consists of the design of the following roads: Bale Lane, Bennet Lane, Dunaweal Lane, Larkmead Lane, Lodi Lane, Old Lawley Toll Road, Silverado Trail - Larkmead Lane to Deer Park Road, and Tubbs Lane.
During the design phase for the project roads, it was determined that only the following roads can move forward with construction in 2024 based on available budget:
• Dunaweal Lane (0.81 miles) (PCI 24)
• Larkmead Lane (1.3 miles) (PCI 28)
• Old Lawley Toll Road (1.1 miles) (PCI 8)
• Silverado Trail, Larkmead Lane to Deer Park Road - Digouts/Crack Seal only (4.2 miles) (PCI 70)
• Tubbs Lane (1.1 miles) (PCI 58)
Total Miles: 8.5 Miles
The remaining project roads (Bale Lane, Bennet Lane, and Lodi Lane) have been scheduled for rehabilitation in 2027. However, this schedule may change depending on when funding becomes available.
On April 9, 2024, the Board approved the Plans and Specifications and authorized to advertise for sealed bids and opening of the bids pursuant to Public Contract Code section 20150.8. Bids were opened on May 16, 2024, and the construction award was awarded to Ghilotti Bros., Inc. of San Rafael, CA for their base bid of $4,342,215 as well as bid additive alternative #2 for $1,403,881 for a total of $5,746,096 on June 4, 2024.
Amendment No. 1 to Agreement No. 240285B increases the contract maximum by $104,945 for GHD to provide geotechnical consultation and material testing for the duration of the construction. The funding for this agreement is included in the project budget presented during the construction award and budget amendment. Construction for this project is scheduled to begin in June 2024.
