BIM, which stands for Building Information Modeling, is a process – a methodology- for creating and managing information on a construction project throughout its lifecycle. The core element of the BIM methodology is the digital model of the building, which is a set of intelligent parametric objects that contain all the information needed during design, execution, maintenance and even dismantling phases. More than just a simple three-dimensional representation, with BIM it is possible to create a dynamic, multidisciplinary and shared information model: the digital twin of the project that contains data on geometry, materials, structure, thermal characteristics and energy performance, installations, costs, safety, maintenance, etc.
Whereas design through CAD is developed through 2D and 3D drawing, BIM design is not limited to visual information, but also offers the designer technical information about the object being shaped and enables advanced workflows capabilities that augment the design process.
