We've run 3 projects on BIM and have now returned to 2D 'vanilla' cad. We created intelligent objects, IFC exports, searched for clashes in 3rd party software, imported the Mech Elecs 3d model, the structural engineers model - cut sections, created elevations - and then sent the whole thing to the quantity surveyor and contractor for them to use. ..and the house of cards came crashing down. A single example, but not the most compeling as to why not to bother - clash detection is a waste of time, unless you really want to filter through '20,000 detected clashes'. But I don't want to detect clashes between concrete and concrete under a clash volume of say 10cm3. But that is asking too much of the software. So 20,000 clashes it is. People will say they use BIM, but they don't. We found nobody in Europe. Unless the QS and construction manager can track objects (including those deleted and replaced) in a model, it's a dangerous software package to use. Oneday it'll come right - but nothing on the current market works at the construction stage of the model - only the fancy 3d glass wall rendering 'show the client' front end.
