Building Information Model

Building Information Modeling (BIM) is a digital representation Building Information Modeling (BIM) is a digital representation of physical and functional characteristics of a facility. As sucof physical and functional characteristics of a facility. As such h it serves as a shared knowledge resource for information it serves as a shared knowledge resource for information about a facility forming a reliable basis for decisions during iabout a facility forming a reliable basis for decisions during its ts lifecycle from inception onward.lifecycle from inception onward.

An “Object” is a term used to describe an electronic element within a BIM model that represents a design element. It may be a 2D or 3D object and it must either have data connected to it (intelligent object) even if it is simply named for counting purposes or it can be a programmed to respond to input automatically (Smart Object) such as a parametric cell.
