Few professional fields have benefited from computer technology as much as architecture and engineering. Computer aided design revolutionised the creation of complex structures, and Building Information Modeling (BIM) is going even further. 4D building information modeling results from adding the element of time to project modeling to more accurately forecast all elements of construction.

The ability to create iterations of virtual models enables extremely detailed forecasts of how a project design will work, how long it will take to build, and how much it will cost. Sydney’s stunning new Barangaroo Reserve project, for example, was a daunting challenge made possible partly through use of…
