3. Concept of Flexibility
• Systems design – ability to modify the mode of operation
• Manufacturing – ability to change the volume, the speed of
delivery or to add new product lines
• Network design – allows to add new nodes or to make new
connections between nodes
• Building design – allows to create spaces that anticipate
complex and changing requirements of human needs
Flexible design accommodates potential movement or change

• Airport design is ‘Complex’
• Facilitates complex interactions among airline, aircraft and airport authorities

• The inherent flexibility allows efficient operation for nearly a century
• Steady and constant growth
• Phases of construction
• No site constraint

9. Flexibility VS Inflexibility
TWA terminal, JFK Airport
• The landmark building of New York opened in 1962
• The building eventually closed in 2001 when American Airlines bought TWA
• Radical and compact plan
• High cost of restoration
• Limited option for alteration

10. Shearing layers of Flexible design
• Buildings are complex - composed of a number of interacting layers

11. Proposed shearing layers of Airport design
• Influence of shearing layers in terminal design
• Terminal as a series of layers and the activities within it is a system
