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

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.

GBA’s Collaborative Approach: Ensuring a Smooth AEC Transition through Integrated Teamwork

Today, our affiliates collaborate on the delivery of innovative results across every stage of project development: from a needs analysis and site planning to asset mapping through design execution and other related services. From our headquarters in Lenexa, Kansas, and regional offices in Colorado, Missouri, Nebraska, North Carolina, Texas and Washington, we can deploy teams for nationwide support.

GBA proudly partners with our affiliate companies, providing clients with total project solutions which promote ease of coordination and enhanced communications among disciplines and services benefiting our clients through a single point of contact.
