To meet the dual goals of preserving the Sydney Opera House for future generations and ensuring its continuing utility as a performing arts center, the Sydney Opera House Trust has adopted building information modeling (BIM) as the core Arup created a structural and arfor its strategic building chitectural BIM model of existing and asset maintenance conditions for potential reconplans. Utzon Architects and Johnson Pilton Walker, in collaboration with a © Sydney Opera House. Courtesy consulting team includUtzon Architects/Johnson Pilton ing Arup, conducted a Walker (architects in collaborareview and study of the tion)–Arup Opera Theatre interior as part of the strategic building plan. The design team included 10 engineers, two 3D technicians (architectural and structural), and specialists in acoustics, ﬁre, and theater planning. The team’s assignment was to create a base as-built model for the structural, architectural, and selected MEP components of the building. BIM forms the foundation for further internal building studies and scheme documentation, ensuring conﬁdence in the redistribution of internal space and existing structural constraints. At the start of the project, the architect and structural engineers used a single software platform – Bentley Architecture and Bentley Structural -- to ensure interoperability between their models. Later, MEP consulting engineers Steensen Varming joined the project, using the same software platform. Because of the complexity of the acoustic paneling throughout the auditorium, the team engaged a building surveyor to conduct a 3D laser-scanning survey. The resulting point cloud, accurate to ±20 millimeters, was converted to a surface model, which became the base model for an acoustic panel model to be used in acoustic analysis software. Working concurrently, the structural engineer created a structural model of the auditorium bowl. The 2D and 3D survey data was constantly reviewed to identify instances where as-built information might give misleading results and require reinterpretation. Engineers also modeled the existing primary mechanical duct runs in and around the Opera Theatre auditorium to help determine where new plant rooms and duct runs could be located.

With the big changes in how the profession does business. With the countless small changes made on every project, every day. How well do you respond to change? Are you sure that every change you make is good for business? Bentley’s Building Information Modeling and Management solutions make change a good thing. By equipping your team to respond to changes effectively, they’ll embrace change and see it as an opportunity, rather than a challenge. And so will you. By changing the way you think about change – you can transform your business. Make change good for you. MakeChangeGood.com © 2007 Bentley Systems, Incorporated.
