If you think Revit is BIM, please stop now.
Revit is a BIM tool, as are similar products from Graphisoft, Bentley Systems, etc. etc. These tools provide the basic 3d design/rendering/engineering components of BIM (and, yes I know, some additional functionality) and associated object technologies.
BIM on the other hand is a business process enabling cradle-to-grave life-cycle management of the built environment supported by a variety of techologies, of which Revit is just “one”.
Those who have spent ten to thirty plus years in the AEC sector know how much a laggard our industry is versus others when it comes to efficient business processes and supporting technologies. As a result, the adoption of BIM will REQUIRE fundamental “cultural changes” in AEC business practices. The basic business foundations of the AEC community must adapt to enable BIM and it’s resulted added value to flourish.
Sure, the risks that come with change are ever present, however, the reward, a productive AEC industry, will benefit everyone… owners, users/occupants, contractors, architects, engineers, software providers, business product manufactuers, and the community at large.
