Re: Update on the 2018 Pavement Overlay Project No. 6001-lSOL
The purpose of this memorandum is to provide an update on the 2018 Pavement Overlay
Project No. 6001-18OL (Project).
Background
On July 24, 2018, City Councjl accepted bids and approved award of the Project to PAL General
Engineering, Inc. (PAL) in an amount not to exceed $2,177,318. The Project included pavement
overlay on La Costa Avenue between El Camino Real and Camino de los Coches, and a small
residential area that includes Viejo Castilla Way, Navarra Drive and Pirineos Way (see
Attachment A).
Discussion
Rubberized asphalt concrete consists of asphalt, aggregate and a rubber/oil binder. After award
of the contract, it was discovered that the rubber/oil binder specified in the contract was no
longer commercially available in California because the primary refinery discontinued making
the material. The product is available in Texas but the refinery is unable to sell to California due
to patent issues.
Moving forward, a polymer-modified asphalt concrete will be specified which will have similar
characteristics compared to rubberized asphalt. Due to this recent change in material
availability, staff will amend the contract specifications to allow for use of a polymer-modified
asphalt concrete, or equivalent, and resolicit the contract.
Approximately $100,000 of construction work was completed in the contract with PAL, which
will be closed out prior to termination of their contract.
Next Steps
The tentative timeline to award the new contract is as follows:
• March 2019 -Amend contract language
• April 2019 -Request approval of plans and specs and authorization to bid
• May 2019 -Open bids
• July 2019 -Request City Council authorization to award
• August 2019 -Award new contract
• December 2019 -Estimated contract work completion
