BACKGROUND INFORMATION
Approval of this item will award a construction contract to Coffman Specialties, Inc., for the Project located in Chino. The Project scope will include the rehabilitation, saw cutting, reconstruction, and striping of the asphalt pavement at the Chino Airport. The additional $2,226,655 budget increase is necessary to fully address unanticipated pavement deterioration and expand the rehabilitation scope to include the severely damaged paving around the commercial hangars, which was not captured in the original bid estimates.
Recent bid results confirmed higher construction and material costs due to inflationary market conditions and FAA compliance requirements for pavement thickness and drainage improvements. This budget adjustment aligns the Project funding with actual bid amounts and ensures the County can proceed with the complete scope of work to maintain operational safety, protect airport assets, and meet federal grant reimbursement conditions.
On May 6, 2025, the Assistant Executive Officer (AEO), pursuant to County Policy 11-15, determined the Project to be categorically exempt from further review under the California Environmental Quality Act Guidelines, Section 15301, Class 1 subsections (a)(d)(e) allowing minor alterations to existing facilities, and Section 15302, Class 2 subsection (b), allowing replacement or reconstruction of existing structures.
On October 3, 2025, the United States Department of Transportation published an interim final rule changing the requirements of the federal Disadvantaged Business Enterprise (DBE) program and requiring the California Department of Transportation to recertify all DBEs based on these new requirements. During the recertification process, no DBE contract goals can be included in any new contract award. The contract for this Project has been modified to comply with this update.
This Project is consistent with County Administrative Office approved Capital Improvement Program Project No. 21-013.
PROCUREMENT
On May 6, 2025, the AEO authorized the Project and Facilities Management Department (PFMD) to advertise for competitive bids. On May 9, 2025, PFMD advertised for bids in the Daily Press, six plan rooms, and on the County Electronic Procurement Network (ePro) via Request for Proposals (RFP) No. ANE223-ANE2C-5880.
On May 16, 2025, Addendum No. 1 was issued to provide clarifications to the mandatory pre-bid meeting date and add the Disadvantaged Business Enterprise goal percentage. On May 19, 2025, contractors attended a mandatory job walk.
On June 11, 2025, Addendum No. 2 was issued to provide clarifications in response to contractors’ questions, revise the bid due date, and add drawings for the utility storm drain lines.
On June 16, 2025, at 10.00 a.m., the following bids were received:
