AEI Ranks Among the Nation’s Top Engineering Firms in BD+C’s 2026 Giants 400 Report

We are proud to share our Building Design + Construction (BD+C) Giants 400 rankings for 2026. These rankings reflect the breadth of work and continued growth across the markets and practice areas we serve. Across them, the questions and scope may change, but our responsibility remains the same: understand what matters to each project, help teams navigate consequential decisions, and develop solutions around clients’ unique priorities.

That work depends on people who bring technical depth to difficult questions and collaborate closely across disciplines, offices, and project teams. Their work makes AEI’s continued growth and recognition like this possible.
