This is an excellent article, Atomic BIM by John Tobin. The question that needs to get answered is how do we deal wtih BIM instead of BIM dealing on us. For example, we need seemless translation between authoring programs. That is Navisworks collision detection data needs to move seemlessly for back into the model and then disseminate that information wirelessly to handhelds for those who need to know, etc. Unfortunately, we are a long way off from there so what do we need to do to get there, and let’s make make sure not to fall into the same traps and lousy work arounds. Anyway read the article.
