There is this idea in the BIM evangelist community that owners, the ones who commission a facility, should specify what BIM is to be used on a project. Not just what BIM will be delivered to them, but how BIM will be used by everyone involved in the project. To me it makes no sense.
An acceptance within the report that BIM costs more upfront but provides overall project savings mainly during the construction phase I’m not sure that this is necessarily true. Anecdotally, consultants are telling me that they are seeing efficiencies through the use of BIM. The question is are the consultant’s savings only related to lonely BIM or do they also apply to collaborative BIM? If savings are also realised during collaborative and level 2 BIM then clients would effectively be adding a premium to a project by not asking for BIM.
