Building Information Models (BIM) can be classified mainly based on their purpose. Furthermore, additional characteristics can be identified to properly define and communicate the model's use.
3D models aimed for construction scheduling purposes - called Construction information Models (CIM) - need to represent the construction scope breakdown intended for scheduling. In other words, the driving aspect of construction is linked to physical construction elements that will be built i.e. columns, slabs, walls etc.
BIM aims to represent as many physical (geometrical) and functional attributes as well as capturing any information related to the building (e.g. suppliers, materials, specs etc). The idea of the CIM is that you digitally represent the building and its elements, as they will be constructed in real life.
For example, a good BIM will represent the envelope physical information by successfully designing the exterior walls probably spanning from bottom to top level, along with all desired design detailing (e.g. sweeps, cuts etc). However, for a good CIM the envelope construction information will be successfully represented by simply designing a simple exterior wall, that’s split by levels without necessarily including the design details of the BIM.
