market and IFC is the best way to exchange data with Revit users and collaborators that use programs other than ArchiCAD.
Fender Katsalidis is looking into other kinds of model checking to include:
•
• LEED information that can be tagged to the appropriate elements for use by rules-based checking programs from which reports can be generated;
•
• Code compliance (automated code compliance has yet to be a factor in the ar-eas in which Fender Katsalidis works; Solibri and similar programs have code compliance checking programs that can be customized for any jurisdiction).
Tagging of elements is useful to team members involved in other phases of the work. Contractors are amending their work for construction-related uses. Life-cycle issues are being explored for information the architect has that should be available to facilities management. One example of this is equipment specifica-tions. Architects are now exploring ways to attach installation and owner manuals to equipment by tagging. Hyperlinks can provide links to PDFs and/or company Web sites (though links on Web sites can become broken when updated.) Managing manufacturing or other data to be accurate and current is an ongoing problem for the building industry.
13.3.9 Automated Code Compliance
Automated code compliance has yet to be a factor in the locales in which Fender Katsalidis works. Solibri and similar programs have code compliance checking pro-grams that can be customized for any jurisdiction. Prior to joining Fender Kat-salidis, Baudin worked in Malaysia. During this time he gained experience with Singapore’s automated code checking. Singapore has been a leader in implementing automated code checking for buildings with its Corenet system.
13.4 Local Criteria that Influences BIM Implementation
From Baudin’s discussions with BIM professionals in the United States, he finds that BIM adoption in Australia is led by consultants when the consultants include the architect and engineers. In the United States Baudin sees the construction industry playing an important role in driving the adoption of BIM. In Australia contractors are becoming more aware of BIM, but they tend to be passive participants. They receive BIM models but do not play an active role in managing the process. Models that architects and engineers provide the contractor are for their own benefit and are not structured in ways to benefit the contractors’ concerns with 4-D (schedul-ing) and 5-D (cost(schedul-ing) BIM of actual construction.

13.5.1 The Dubai, Project, Dubai, United Arab Emirates
The Dubai project was a mixed-use project in Duabi, for their client Nakeel. It is typical of experiences Fender Katsalidis has had where they were the one consul-tant team member using BIM. BIM was a critical part of this project for Fender Katsalidis as the complex fractured and triangulated facade could not have been designed and documented without a 3-D methodology. Fender Katsalidis was origi-nally hired for full design services from design through construction administration.
The project lasted 18 months and was halted due to the global financial crises of 2008. During the design phase Fender Katsalidis received data in 2-D format from their consultants. They modeled all the design in 3-D including the structural and façade elements.
Fender Katsalidis was able to use the BIM model to unfold and explain this complex facade to contractors. They also used the model to derive the floorplate profiles which varied at each floor. This was achieved by modeling the project in 3-D and embedding the data to be extracted during documentation for construction.

Lesson learned for this project, says Baudin, was that it was good learning experience for the firm for the practice of using BIM in their work. BIM enabled them to document complex folded facedes. The BIM documentation allowed them completely new ways to represent complex 3-D shapes. Until then they had, said Baudin, been caught in a mindset where they would use BIM to replicate the same kinds of drawings they had done in 2-D. They were now able to use 3-D drawings to more clearly represent their design.

13.5.2 The Moorilla Pavilions
The Moorilla Pavilions is a smaller-scaled luxury hotel in Tasmania, incorporating three luxury hotel pavilions. These hotel pavilions has a complex geometry simi-lar to the Dubai Ice project. This was the first time Fender Katsalidis successfully worked in a BIM collaboration with a fabricator. Fender Katsalidis produced an external cladding shell of the building which the steel fabricator imported into a shell model then returned to Fender Katsalidis in IFC format to integrated with the Fender Katsalidis model. This allowed Fender Katsalidis to produce accurate internal fitout modeling without internally clashing with any steel structure. This integrated approach was faster and more accurate than traditional BIM approaches when a structural model is first sourced from a structural engineer, and then exten-sively reworked by a fabrictor. This process would not work in all cases, but does lend itself well to steel framed buildings.
Figures 13.4 and 13.5 show the front and back views of the steel frame of each pavilion. In Figure 13.6 and 13.7 the architectural model of a pavilion is shown from the front and back view respectively. By constructing a virtual model of the steel frame Fender Katsalidis could integrate the frame with their architectural design.
