BIM objects

Building Information Modeling (BIM) is the digital management of the information processes for the design, construction, and management of building projects. The use of the digital model – the representation of the physical and functional characteristics of a structure – promotes interoperability and interaction among the various stakeholders and the result is a highly interactive environment capable of adapting to changes. According to “Delivering value with BIM: a whole of life approach” book, a BIM object is a model element which contains: *Information that defines the product or element *Geometric characteristic of the physical product or element *Visualization data giving the object a recognizable appearance *Functional data that allows the object to be positioned or to behave in a certain manner. Therefore, a BIM object is not a simple digital representation in 3D, but an intelligent object as it contains the metadata that describes what kind of object it is, its classification, performance values, the material type, expected lifetime, manufacturer, maintenance, its behavior and also information regarding sustainability and energy efficiency and so on. This information is crucial for the management of the object along the whole life-cycle of the building project. How can BIM objects be classified? Which are their sources? Read less
