‘Convergence of technologies enables 5D design modelling’

Malaysia: Convergence of geospatial, engineering design and 3D — GIS, CAD, BIM [building information modelling] — has allowed Autodesk to offer modelling solutions in 5D, which enhances both sustainability and emergency response planning, according to Geoff Zeiss, Director Technology, Autodesk.

“The 5D approach allows tight control of 3D design as well as project management in a time sequence [fourth dimension] as well as detailed monetary implications to any real-time changes. The ability to immediately see monetary implications of any design or project variations constitutes the fifth dimension,” said Zeiss.

He said that this approach of using electronic models allowed in-depth collaboration over networks. “Clash detection is one of the problems that can be managed through intelligent modelling, which also enable 4D management. This involves using a 3D model that is linked to project management applications, which run through project instances, thus allowing a project to be viewed in time sequence.”

“Geospatial is used in many different processes around location-based applications or GIS systems,” Zeiss said, adding that such intelligent 5D modelling would be useful to both public service and business organisations throughout Asia.

“For example, Malaysia’s Penang state is in many respects leading the world in using such solutions for some years,” he said. “One such recent project is the mapping of underground utility networks in Penang.”

“One of biggest benefits of the converged modelling approach is the ability to communicate the impact of projects and infrastructure across to different audience, often non-technical audiences such as local authorities,” Zeiss said.

“Google or Bing would show the externals of buildings in 3D but an emergency fire team would also need to see inside buildings,” he said. “The combination of geospatial with engineering data through any internet browser is invaluable in such conditions.”

“About 90 per cent of information relating to environmental assessments and plans is already geotagged, according to a recent Inspire confidence,” said Zeiss.
