What will be the first large US building construction project to go paperless? 3D BIM models hold all that and more over traditional 2D drawing sets. There are first generation 3D delivery formats for packaging model systems for contractor bidding and construction. Wisconsin and Texas require BIM on public projects. Contractors can build from it and I have heard them tell owners not to make drawings for their benefit. GSA is requiring BIM and some private sector owners are ready to take the next step and have the design reviews 100% 3D.
Despite the need to modernize all the paper processes currently in place, someone who is leading advances in lean practice in the AEC industry will soon have enough stars aligned to pull off a construction completion without paper drawings. Maybe without 2D altogether.
