About OBEC toggle

We’ve grown, but there are some things we’ll never change.

In 1966, a small team of bridge engineers founded OBEC as a subsidiary of a construction company in Springfield, Oregon. In 1971, they struck out on their own, bringing with them a strong sense of the connection between office engineering, field construction, and the role infrastructure plays in our quality of life. More than 50 years later, while we do a lot more than just bridges, our tradition of quality remains unchanged.
