Company History
From Humble Beginnings to Trusted Industry Leaders
In 1966, John Banicki opened the doors to what would become one of Michigan’s most respected engineering consulting firms. What started as a small office and lab on Woodward Avenue — just south of Detroit’s iconic Eight Mile Road — has grown into a firm with over five decades of innovation, integrity, and impact.
TEC was built on a simple idea: provide expert consulting grounded in real-world construction experience and problem-solving for buildings and structures already in service.
“I saw a need for a firm that didn’t just support new construction, but could also tackle the complex issues facing existing buildings — especially those built improperly or facing performance issues.”
— the late John Banicki, PE, Founder & Chairman of the Board Emeritus
Growth Driven by Purpose
As TEC’s reputation grew, so did the company. We moved our headquarters to Ferndale in 1968, then to Troy in 1973. In 1986, we expanded again — doubling our size with the addition of a second 10,000 sq. ft. facility. Along the way, we opened branch offices in Detroit, Lansing, and Ann Arbor, extending our reach and capabilities throughout the state.
From day one, our services have evolved to meet the ever-changing needs of our clients. Today, TEC offers expertise across:
-
Construction Engineering
-
Geotechnical Engineering
-
Materials Testing
-
Building Envelope Evaluation
-
Structural Analysis
- Environmental Services
A Family-Owned Legacy
Katherine Shanahan, who worked alongside John at Detroit Testing Lab (DTL), was instrumental in getting TEC off the ground. In 1971, John and Kathy married — officially making TEC a family business. Kathy became a Principal and eventually assumed the role of President in 1987, bringing a strong leadership presence that helped guide TEC into the future.
John remained actively involved as Chief Executive Consultant and Chairman of the Board Emeritus, continuing to shape TEC’s direction and culture.
Building the Next Generation of Leadership
In 1997, TEC welcomed Carey Suhan, PE and Ruben Ramos, PE as Vice Presidents and shareholders. Carey, who joined TEC in 1989, continues to lead our Geotechnical Engineering and Environmental Services divisions with deep technical insight and strategic direction.
After many impactful years of leadership, Ruben Ramos has retired — leaving behind a strong legacy of service and growth. In his place, we proudly welcome Scott Hoffman, PE, as Manager and Principal. Scott brings decades of experience and now leads our Building & Infrastructure Engineering and oversees Construction Services divisions with a commitment to innovation, quality, and client success.
