i think it can save a lot of duplicate work.
That is true. But this does mean that the BIM model must comply with certain agreed upon standards. At any point in time other participants in the building process should know which parts of the model are exact and which still have to be checked and validated.
A nightmare scenario would be finding out on site that the windows, that were just delivered, do not fit in the holes in the prefabricated walls because sub-contractors made wrong assumptions and/or the architect forgot about tolerances in his BIM model. To be used by a structural engineer, assuming he also creates the detailed structural drawings, the BIM model would have to have a high level of accuracy.
