Sector Leader Aviation

Karl Traeger


Bachelor of Architecture,
University of South Australia


An expert in aviation architecture, Karl has been instrumental in designing and delivering elegant, integrated airport terminals and security projects across the Asia-Pacific, including China, Singapore, Indonesia, and Australia’s major capital cities.

Over the course of his 25-year career, he has played a leading role in significant projects such as the Singapore Changi Airport Terminal 1 expansion and refurbishment, Soekarno-Hatta International Airport’s new Terminal 3 in Jakarta, and Melbourne Airport’s Northern Infill project. His expansive understanding of the complexities and technical requirements of airport developments put him in a unique position to help clients realise their unique objectives and aspirations.

An excellent communicator, Karl is always focused on creating a great, collaborative experience for clients and stakeholders. He has steered design teams towards creative solutions through all project stages, including master planning, visioning and design workshops, concept generation, and schematic and detailed design.

His diverse career encompasses mixed-use, civic, hospitality, tourism, commercial, retail, master planning, defence and transport projects – experience he has leveraged developing landside and business park concepts for several Australian airports.

Karl is committed to aviation architecture that is sustainable, adaptable and socially advanced. He was the driving force behind A-UX, an inclusive design tool allowing people with disabilities and travel anxiety to navigate complex and often stressful airport environments before even leaving home.
