The Building Information Modeling, acronym: BIM, indicates a process through which it is possible to optimize the planning, construction and management of buildings.

NIBS (National Institutes of Building Science) defines BIM as the “digital representation of physical and functional characteristics of an object” and in a more specific meaning of a building or infrastructural.

BIM is therefore not a product or a software application, but it is an operative methodology of planning, design, implementation and maintenance, made possible through the realization of a three-dimensional dynamic informative model, inside which all the graphic information is included documents concerning each individual element.
