The centre's extension features an 11-screen cinema complex, an underground link to the adjoining train station, a colonnade restaurant and cafe precinct, and more than 70 new shops.
Arup provided detailed facade engineering design and fabrication documentation of the glass and secondary support steel.
The 110-meter-long by 20-meter-high facade consists of 2425 square meters of bolted steel and glass, including a glazed footbridge spanning 21 meters that links the new and existing complexes.
Arup estimates that its use of Bentley's Building Information Modeling (BIM) solutions on this project saved AUD$270,000 due to error-free fabrication and installation.
Some 550 glass panels plus support steelwork were coordinated, detailed, and installed without error and on time.
In addition, automated production of documentation for the glass panels saved Arup roughly three man-weeks in time as compared with conventional approaches to documentation.
The bolted glass facade features a series of frameless glass panels, fixed back to horizontal transom box sections with patch fittings at each corner and at midspan.
These transoms are then fixed to radial mullions with connections back to the primary building structure.
A section through the building revealed that the geometry of the facade was described by an upper radius, a step back into the building, and then a lower radius.
A plan view showed that the geometry was further complicated by two bends along the length of the facade to keep within the site boundary.
This resulted in the glass panel becoming nonrectilinear in elevation where a joint line occurred.
Adjacent to the main facade is a vertical cylindrical facade, and a return wall connects this to the main facade.
Arup had to maintain a constant vertical joint width, which meant the nonrectilinear panels all had slightly different top and bottom lengths.
The design, glazing installation, and secondary steelwork for the facade had to be completed within six months so the cinema could be fitted out.
This all had to be done while also accommodating the lead-in time required to manufacture and deliver the glass from an overseas plant.
Using MicroStation's DGN file format, Arup could easily share information with its design partners.
This enabled a highly coordinated secondary steelwork model, which was installed without error.
Coordination was carried out in a 3D environment, facilitating an understanding of the errors and omissions throughout the design team.
By extracting production drawings from the 3D model, Arup could produce extra drawings as required.
This ensured that the complex geometries and connections could be easily understood.
By modeling the glass panels in Bentley Structural, Arup could ensure a correct size and location.
This information could then be extracted and presented to the glass fabricator in a table format, which is more appropriate for its manufacturing processes.
The automatic extraction of this information also eliminated rekeying errors.
The workflow that Bentley Structural and MicroStation provide allows Arup to simultaneously produce a rich 3D model and standard 2D documentation.
Moreover, the 3D model can be interrogated in a number of ways, providing a broad spectrum of information for use by various members of the design team. Request free introductory details about products from Bentley Systems ...
