BIM is often equated with modeling—this is a common perception among many people, not only those in construction companies. Objectively, the application of BIM in China began primarily within design institutes. Initially, one of the main functions of BIM for these institutes was indeed modeling.
However, the ultimate goal of BIM is to create a foundational model during the design phase. As the construction process advances, relevant data and information are gradually integrated at various stages, enabling collaborative and shared usage.
For instance, during the design phase, BIM emphasizes three-dimensional spatial information. In the construction phase, the focus shifts to engineering quantities, timelines, and cost data. During the operation and maintenance stage, BIM is mainly concerned with equipment and facility maintenance information.
Therefore, while modeling is a function of BIM, it should not be mistaken as the entirety of BIM.
How should we understand and define BIM? To clarify the perspectives of different stakeholders, BIM should possess three key characteristics:
1. Visualization
2. Information carrier
3. Collaboration
