Extended Description:


Commonwealth was established in 1988, following the closing of another major engineering firm's Jackson, Michigan, office. The founders had worked closely together on domestic and foreign electric utility projects for many years out of the Jackson office. Rather than leave Jackson, Commonwealth's founders left the company and took action to incorporate under a name that was—and remains—well known and respected in the electric power industry. The group devoted itself to structuring a new employee-owned company with the intent of upholding the previous Commonwealth Associates Inc.'s reputation for providing high-quality engineering and consulting services. Today, Commonwealth's staff of approximately 270 professional and technical employees represents one of the most skilled, experienced technical resources available to analyze, plan, design, and construct electrical power projects.

Office Locations

To serve clients throughout the United States efficiently, Commonwealth is headquartered in Jackson, Michigan, and currently has branch offices in Everett and Liberty Lake, Washington; Kennesaw, Georgia; and Columbus, Ohio.
