design: to do or plan something with a specific purpose or intention in mind

Our design philosophy is to deliver practical solutions that facilitate the construction, use, and maintenance of a facility over its lifetime. Our interdisciplinary approach and use of inter-office expertise allows us to engage our best people on your project, regardless of the project size.

We are prequalified/certified by local and state agencies in various design categories nationwide. SE3 has been involved in the design of both traditional delivery - design, bid, and build - and alternative delivery - design and build - projects.
