Building information modelling (BIM) is one of the most fundamental changes to affect the global construction industry. The growing worldwide adoption and implementation of this technology allows for powerful data-based modeling, visualisation, analysis and simulation capabilities that are revolutionizing all aspects of the construction process.

The leading software fuelling this growth is Autodesk Revit. Purpose-built for BIM, Autodesk Revit Architecture helps architects and designers capture and analyze early concepts, and then better maintain designs through documentation and construction.

The current perception has been that BIM can only really be applied to new-build projects. However, as a result of the economic downturn, these projects are few and far between. In their place retrofits on existing sites have become a popular, albeit unavoidable, alternative.

This has created a demand to model existing buildings in Revit and overcome the inherent problems associated when modeling complex, aging buildings and structures.
