Structural Engineering Institute (SEI)

The Structural Engineering Institute (SEI) Orange County (OC) Chapter allows our members to interact with other professionals in the structural field of civil engineering.  We regularly send active Orange County branch members to SEI Congresses held on a annual bases across the country.  We hope the Orange County Branch members will learn new ideas and find interesting speaker topics that we can bring back to our local branch members.  Periodically SEI OC holds joint events with the Orange County Branch during branch general meetings.  The Orange County Branch and the SEI OC work together to provide continuing educations events that are relevant SEI members. We hope you will come out and participate in our institute and work with us to build a strong organization.
