Eureka TowerEureka Tower
When completed, the 90-story Eureka Tower in Melbourne, Australia will be the tallest residential building in the world, rising 985 feet (300 meters) above street level. It is being built in the arts district on the Yarra River within the Southgate precinct of the city. With a facade of glass and aluminum,

The builder, Grocon Pty. Ltd., takes pride that this large-scale venture is right on schedule.
Nonda Katsalidis, principal and design director of the Melbourne-based architecture firm, explains: "by exploiting the intelligence of the 3D computer model, we have been able to not only provide construction documentation when needed by the builder, but to prototype the design options as part of that process."
Fender Katsalidis Architects (FKAU) used ArchiCAD from Graphisoft for
the design and documentation of the project, and information from their
digital models continues to inform the construction process.

Rethinking Design Processes
For good design to emerge, it is essential that an architect respect the need for multiple iterations in design development despite the pressure of limited time available to do that work.
David Sutherland, director of planning at FKAU, believes that by fully exploiting the strengths of ArchiCAD, his firm has found a way to concentrate on their core skills of design and management. While the architects test their design ideas, other participants provide much of the construction information.
By using ArchiCAD, which stores all the information about the building in a central database, FKAU simulates the building in three dimensions throughout the design and documentation process.
With ArchiCAD, changes made in one view are automatically updated in all others, including plans, sections, elevations, architectural and construction details, bills of material, window/ door/ finish schedules, renderings, animations, and virtual reality scenes.
This level of integration makes the management of the project easier and faster and allows the designer to design instead of draft. Sutherland says drafting represents wasted effort because it produces only lines, and it is more important to be creating byproduct-rich 3D information.
The byproducts of the ArchiCAD database also include descriptions of materiality and quality, specification data, and analysis of environmental, financial, and construction issues. In fact, the architect could continue coordinating such information for the life of the building through computer-aided facilities management.

Object-Oriented Design in Practice

For 2D output, the firm uses a separate Graphisoft application, Plotmaker, which allows them to batch-plot drawings. Live design information is brought into Plotmaker from the 3D model, and live document information is brought in automatically from a Microsoft Access drawing registration/ issue/ transmittal database.
