A partnership of Utzon Architects and Johnson Pilton Walker along with consulting engineers Arup worked closely on the review and study of the Sydney Opera House’s interior. The primary goal was to create a base-coordinated structural, architectural, and MEP as-constructed model. This existing-condition BIM allowed further internal building studies and scheme documentation to be completed with a great deal of confidence in the redistribution of internal space and existing structural constraints.

Bentley Structural and Bentley Architecture were used by the various project disciplines to facilitate interoperability between their models. Bentley’s BIM solutions demonstrated how easily an extremely complex geometry could be generated, manipulated, and documented. The ease of integration of other subconsultant documentation—such as DWG and IGES formats—without the time-consuming conversion process saved numerous man-hours.
