Building Information Modeling (BIM) is a new approach to building project delivery that uses data to create an information-rich model of a facility to improve the design, construction, and operation of the facility.
Building - the entire lifecycle of the building is considered (design/build/operations). Information - all information about the building and its lifecycle is included. Modeling - defining and simulating the building, its delivery, and operation using integrated tools
BIM has the potential to revolutionize the way facilities look and function, the way they are planned, designed, constructed, and operated throughout its life cycle.
