Collaborative work is a huge problem, as there is only one master model, unlike CAD, where each floor plan, or even partial floor plan, can be an individual file, as can details, etc. This allows many to work on different portions of one project at a time. Likewise, different disciplines can reference in each others plans to allow simultaneous work with proper coordination. For simultaneous work (at least as I understand it) BIM requires different versions of the master model to be worked on and merged together later. Thus, conflicting edits can be made, and no one has all the current information. Early BIM software I used in 1993-94 was a disaster. Basically, nothing worked correctly. Our energy engineers seem to be the biggest fans of BIM at this point.
