The judgement call
Account-gated at launchThe decision to expand the existing terminal rather than build a separate arrivals terminal demonstrates a focus on optimizing existing infrastructure. - The investment programme aims to redefine the airport's identity and enhance the passenger experience. - The emphasis on assembly-on-site highlights a modern approach to construction logistics in a live airport environment.
Key engineering challenges
Expanding the existing 1991 terminal building by 33% while maintaining full airport operations and passenger flow. - Integrating new facilities and infrastructure seamlessly with the original, iconic terminal design. - Prioritizing assembly-on-site over traditional construction to minimize disruption. - Addressing the challenges of integrating old and new terminal systems, including the people mover system.
