Where bids are posted
Owners post on their own procurement pages, and many state and local opportunities also appear on OregonBuys, Oregon's statewide eProcurement system. Register both on OregonBuys and with the specific owners you target, since not everything flows to one place.
Certification: COBID
Oregon's Certification Office for Business Inclusion and Diversity (COBID) certifies MBE, WBE, ESB, and DBE firms. Certification can qualify you for participation goals and set-aside opportunities and helps prime contractors meet their goals on public work.
Prevailing wage
Oregon's prevailing wage rate (PWR) law, administered by the Bureau of Labor and Industries (BOLI), applies to most public works in the state. Federally funded projects add Davis-Bacon — see our Davis-Bacon prevailing wage rates lookup. Use the right determination for each job.
How to compete
- Register on OregonBuys and with each owner you want to work for.
- Prequalify with ODOT for state highway work — see contractor prequalification.
- Get COBID certified if eligible.
- Track deadlines across owners so lettings don't slip past you.
Bottom line
The Portland market is active across city, county, regional, transit, port, school, and state owners, with a statewide system (OregonBuys) on top. Register broadly, certify through COBID if you qualify, price PWR correctly, and monitor every relevant portal.
