Continuously evolving the improvement of complex environments

For more than 50 years, GBA has grown its team and service offerings to support clients within complex and highly specialized markets across the United States. We evaluate our clients’ needs in order to deliver integrated solutions for architectural and engineering design and construction services (AEC). We put an emphasis on the use of innovative AEC technology that puts data-driven solutions in the hands of GBA’s experts.

Our History & Growth

GBA has seen exponential growth since George Butler first launched his consulting engineering firm in 1969 with its focus on site development and civil engineering. In the years since, we have continued to strengthen these foundational offerings. In addition, we have also grown through acquisitions and strategic in-house expansions, positioning us to better serve our clients. Today, GBA has 15 office locations nationwide.
