Westfield Parramatta, the largest shopping center
in Sydney, Australia, contains more than 350
retail shops and a cinema complex. The center’s
extension features an 11-screen cinema complex,
an underground link to the adjoining train station,
a colonnade restaurant and café precinct, as well
as 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 façade consists of
2425 square meters of bolted steel and glass,
including a glazed footbridge spanning 21
meters that links the new and existing complexes.
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.
ings 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 their
manufacturing processes. The automatic extraction
of this information also eliminated re-keying errors.
The workflow that Bentley Structural and
MicroStation provided Arup allowed it to
produce a rich 3D model and standard 2D documentation simultaneously. The software then
allowed for a number of ways to interrogate the
3D model and make that information useful to
others on the design team. ;
By extracting production drawings from
the 3D model, Arup could produce extra draw-
