In recent years, Building Information Modeling (BIM) has rapidly developed in China, with many companies adopting it for their projects. However, some have found that the results are not as impressive as advertised. This may stem from misunderstandings about what BIM really is. Today, let’s explore what BIM is not and the advantages of applying BIM.
First, let’s clarify what BIM is not:
1. A model containing only 3D data without any object attribute parameters is merely a visual drawing tool, not BIM.
2. Models that lack behavioral characteristics, do not possess parametric intelligence, or cannot adjust position and properties dynamically are not considered BIM.
3. Entire buildings represented by interlinked 2D CAD files that do not display consistent and reliable parametric intelligence cannot be classified as BIM.
4. A model that changes size in one view but lacks linked updates across other views simultaneously is not BIM.
Building Information Modeling (BIM) is an engineering data model rooted in 3D digital technology that integrates diverse and relevant information about construction projects. It represents a detailed expression of project-related data. Many people mistakenly think BIM is just 3D design, but the core of BIM lies in the “Information” it manages. Effective information management allows all stakeholders to gain a clearer understanding of design and construction data, significantly reducing project risks and enhancing control. When BIM information management supports the entire construction project lifecycle, its value is fully realized.
