About Electrical Substations

We offer structural engineering and steel detailing for electrical substation (15 KV to 500 KV) and transmission projects. Our staff has over 60 years combined experience on substation projects. We also provide structural engineering and CAD services for other types of projects.
Principals - Gary A. Johnston PE and Sayan Yadmark (retired).
Our projects are located throughout the world and include substation structures (steel, aluminum, tubular, wide flanged, latticed, and tapered tubular), transmission towers, industrial structures, highway sign structures, and foundations.
As a small engineering firm, we can offer the careful, detailed and complete services that substation and transmission projects demand. All engineering services are provided by the principals, or are completed under their direct supervision.
