Vendors Registration for Small Construction/Public Projects (California Uniform Public Construction Cost Accounting Act)

Yolo County solicits contractors for small construction/public projects under $200,000 as specified in the California Uniform Public Construction Cost Accounting Act (CUPCCAA).  For projects of $60,000 or less, the County can have a contractor perform the work by negotiated contract.  For projects between $60,000 and $200,000, the County will conduct informal solicitations by reaching out to registered contractors on the County's CUPCCAA list.  Contractors can apply to be on the County's CUPCCAA list by submitting an application through the County's third party registration service, Quality Bidders, at the following link:

Insurance Requirements

In instances where vendors, contractors and consultants, or their representatives, will be working on County property, the County requires that a certificate of insurance, with coverage at the minimum limits required by the Contract, be on file with the Procurement Division. Separate endorsements, naming the County as “Additional Insured”, are required for General Liability and Automobile Insurance. In addition, Workers’ Compensation Insurance that meets the minimum State requirements must also be provided.   Refer to the Sample Insurance Documents to review the requested certificate of insurance, endorsement pages, and required Additional Insured language.

Purchase orders and Contracts will not be issued until Procurement staff reviews and accepts the Vendor's insurance.  Vendors shall not perform any work prior to the issuance of a Purchase Order or Contract.
