Multnomah County Prequalification Program, Revised April 2018

Purchasing oversees its own prequalification program for General Contractors interested in doing business with Multnomah County. The goal of the program is to ensure that contractors are responsible in their business practices by determining the project level that the contractor would be eligible to compete for based upon their resources (e.g., working capital and equipment), expertise, experience, integrity, and necessary licenses and insurance.
