Contractor Prequalification

Prequalification with the City of Portland (City) is required of all prime contractors bidding on public improvement projects with an engineer’s estimate of $250,000 or greater, as specified in Portland City Code 5.34.510(A). 

Contractors interested in bidding a City construction project that are not currently prequalified must complete and submit the City of Portland Construction Prequalification Program Prime Contractor Application with all required attachments for the Prequalification Board’s evaluation of qualifications and determination of bidding limits.  

Portland City Code states that contractors must demonstrate to the City’s satisfaction that they are a responsible offeror prior to bidding on public improvement projects.  The City makes this determination through the Prequalification process, where contractors demonstrate that they meet the Standards of Responsibility pursuant to City Code 5.34.500.

A contractor may submit a request for Prequalification at any time by completing and submitting the City of Portland Construction Prequalification Program Prime Contractor Application.  The date on which all required information has been received by Procurement Services will be considered the receipt date of your prequalification application. For more information see the Application Instructions. 

All Applications will be evaluated and bidding limits determined by a Prequalification Board that meets approximately every two weeks. The application review and approval process can take up to four (4) weeks to complete. Once prequalified, a contractor’s bidding limits are in effect for two (2) years.


If currently prequalified with the City of Portland in one or more classes of work and you are seeking prequalification to meet the requirement of a specific Invitation to Bid currently advertised, complete the Project Specific Prequalification Request or Increase Request Form.  Available to download below.

The deadline for receipt by the City is usually ten (10) calendar days prior to bid opening; however, it is important to review each set of bid documents to determine the specific requirement for that project.

There are some construction projects that require specific expertise, prior experience, special equipment, or are of high risk and are outside of the criteria necessary for prequalification in one of the City’s general classes of work.  For these projects, a Special Prequalification application will be included in the bid documents. Contractors intending to be specially prequalified to bid on that project must complete the Special Prequalification application and submit it by the date and time stated within the solicitation.

Applications are available to download below.  Questions?  Contact us at 503-823-5578
