There are many definitions of BIM out there and all are accurate in most senses. BIM is an intelligent model-based process to create building model data that is essentially coordinated and computable and thus AEC professionals can more efficiently design, build and operate buildings and infrastructures. A true BIM model consists of the virtual equivalents of the actual building parts and pieces used to build a building which means a building can be “built” even before its physical realization through a virtual model.
