How to "piggyback" on King County contracts

Download the Cooperative Purchasing Agreement Form

Under RCW 39.34.030, local government agencies can use contracts from other jurisdictions through a process called "piggybacking." This lets municipal governments use contracts awarded by "host" agencies, saving time and possibly getting better prices and terms than they would on their own.

To piggyback on a contract awarded by King County, check the list of approved Cooperative Purchasing Agreements provided below. These are the jurisdictions that are already authorization to use King County contracts.

If your agency or jurisdiction doesn't have a Cooperative Purchasing Agreement Form, you can download one and have it signed by the appropriate authority. Once it's signed, email it to procurement.web@kingcounty.gov. King County will respond promptly after the Chief Procurement Officer signs the form and uploads to the designated list.

To find the contract you want to piggyback on, look at the Awarded Contracts Log. This is where King County publishes goods and services contracts from the Invitation to Bid process. If your jurisdiction needs more documents related to the contract, send a request describing your needs to procurement.web@kingcounty.gov.

It's important to know that your jurisdiction is responsible for initiating work or placing orders with the contractor. King County is not directly involved in this process. Additionally, the criteria for piggybacking are determined by your own municipal code and RCW, not King County procedures. For more details, visit the MRSC website.
