About the Oregon Chapter
The Oregon Chapter of the Design-Build Institute of America is committed to educating professionals across the state on how to procure, execute and deliver design-build projects while forging connections, partnerships and friendships throughout the industry. The chapter’s membership includes representatives from architecture, engineering, contractor and developer firms of all sizes from across Oregon and Southwest Washington, as well as numerous state agencies and many cities and counties. Among the chapter’s initiatives are bimonthly breakfasts; an annual owner’s forum, summer social event and golf tournament; and events throughout the year geared toward young professionals interested in learning and networking. Ultimately the chapter works to grow understanding of not just “traditional” design-build delivery but also the growing progressive design-build delivery method and other alternative forms of delivery and helping its industry and owner members best choose the most appropriate delivery method for each of their projects.
