Commissioned by Adelaide Airport Limited, this large-scale structure has been designed as both a screen to a multi-deck carpark and as a landscape device to give spatial definition to the new plaza at Adelaide Airport. It serves as a memorable gateway experience for arrival and departure. The truss frame structure is a 3D, twisting form which has an elegant stainless steel woven mesh wrapping around two sides. At night the frame and mesh will be dynamically lit to enhance the arrival and departure experience.
The innovative use of parametric software was crucial to the conception and development of the design, through to documentation and beyond. The key to its success was the strategy taken to construct, use and share the 3D model within the design process. Research was conducted to find out how other models had been built and shared at this scale. The GHD Woodhead model was built in a way that allowed continual refinement and change without the need for rebuilding. Manipulations of form automatically changed the structure to follow the shape.
The structure was set up to, for example, allow spans between structural nodes to be updated simply by inputing the span in the parameter callout. All programed structural nodes would update their span distances without the need for direct modelling. Automatic schedules were set up to give information such as surface area directly to the quantity surveyors. The model was shared collaboratively between architect, engineers, cost consultants, lighting consultants, landscape architects and steel fabricators. It was used directly in the concept and detail design, visualisations, documentation drawings as well as being sent out as a 3D file to all tenderers. This process allowed for continuous, integrated feedback and refinement, and a much faster timeframe for design and documentation than that of a traditional workflow.
