Aviation at LEO A DALY
Landside and airside facilities that support passenger experience and airport operations.
Our aviation team delivers projects that blend functional performance with elevated design, enhancing both airport operations and the passenger experience. From terminals and towers to parking structures, and master plans, we see every touchpoint as an opportunity to improve efficiency, safety, and comfort. Whether advancing critical infrastructure, reimagining passenger journeys, or supporting sustainable growth, we approach each project as a platform for innovation and problem-solving. Backed by more than 70 years of industry leadership, our experts bring a deep understanding of airport operations and a commitment to shaping the future of aviation.
-
We design aviation environments with a deep understanding of how airports and airlines operate, day to day, peak to peak, and under pressure. With over 70 years of aviation experience, our work on terminals has reached two-thirds of major U.S. airports, impacting over 447 airports nationwide.
-
Our architecture and engineering teams collaborate from the start, ensuring design intent aligns with constructability, systems performance, and long-term operations.
-
We specialize in aviation environments where failure is not an option. Every detail from passenger flow to air traffic control systems is designed to perform under pressure. Our 300+ ATCT and TRACON projects, along with decades of collaboration with the FAA, showcase our ability to deliver complex, mission-critical aviation systems reliably.
-
We balance bold, inspired design with practical solutions that work today and adapt tomorrow. From leading the first LEED-certified airport terminal at LAX to developing best practices for sustainable airports in China, and implementing explosives detection systems and security screening standards, our projects combine design excellence, operational reliability, and forward-looking innovation.
What we do
-
Terminals and Landside Facilities
From planning and conceptual design through execution, our team creates terminals that respond to place and culture while optimizing passenger flow, operational efficiency, and the needs of airport stakeholders.

-
Air Traffic Control Towers
We plan and design Air Traffic Control Towers that deliver clear visibility, operational efficiency, safety, and full regulatory compliance. We support the complex workflows of controllers while integrating seamlessly with airport operations.

-
Hangars
We work with private aviation, commercial operators, airports, and federal clients to design hangars that meet the specific requirements of aircraft storage, maintenance, and operational efficiency.

-
Airline Solutions
We design airline-focused solutions— maintenance and inflight services, lounges, hangars, operational centers—to optimize efficiency, support operations, and enhance passenger experience.
