Here's How

Whether it’s a terminal, hangar, support structure, parking garage or transit connection, aviation facilities require highly specialized experience. With more than 900 projects under our belt, we know the ins and outs of aviation design and construction. We relish the challenge of fine-tuning a structure – from scratch or by updating or expanding an older one – to adapt to changing needs, optimize operational efficiency and the traveler experience, and accommodate new technologies. 

We apply creative problem-solving and cutting-edge technology to invent new ways of solving difficult engineering problems. The result? Efficient, constructable designs for complex, iconic forms. 

Creative structural design is just the beginning. Our holistic approach – one that combines multidisciplinary services such as sustainability and resilience consulting, protective design and security, and façade and construction engineering, and more – streamlines design and construction.

With a portfolio of projects spanning four continents, we bring a global perspective to any local challenge. And not just terminals. We also design the support facilities that are essential to the operation of any airport, such as aircraft maintenance hangars, control towers, ground equipment maintenance facilities, parking garages, cargo handling facilities, and even police stations and airport rescue and firefighting (ARFF) stations.

We can help you with a wide range of in-house services and expertise, including:
