BIM IN UNITED STATES
In the US there is quite a bit of use of BIM in the US public and private sectors, at least at the level of using it to model buildings and their components and how they fit together. There is less use of BIM for simulation and for connecting and tracking other kinds of information that are used in the building process.
There is a lot of use of BIM for the physical representation of buildings, using models to do clash detection, visualization, but less for project coordination, simulation, and optimization, as well as asset and facility management.
How is the US leading the change?
