Let’s discuss What exactly is BIM? What can it do?
Literally, the term “BIM” stands for Building Information Modeling. The author believes that the Chinese translation of this phrase, “building (object) information modeling,” captures its essence. However, in China, while “building information modeling” is commonly used, the word “model” alone does not fully express the dynamic, ongoing, and progressive nature implied by the English suffix “-ing” in “Modeling.” As a result, some translators emphasize the active process aspect of “modeling” to avoid the misconception that BIM refers solely to a static 3D model.
The author also notes that the term “modeling” might mislead people into thinking BIM is just a modeling level or stage. Instead, BIM should be understood as a process — a continuous behavior involving the dynamic transformation and refinement of building information over time.
In brief, BIM (Building Information Modeling) integrates building information, parameters, scheduling, and other data directly into 3D model components. This allows each element of the model to carry relevant information. The model and its data can be continuously refined, adjusted, and supplemented throughout the building’s entire lifecycle, including phases like evaluation, planning, design, cost estimation, supervision, construction, maintenance, renovation, demolition, and new construction.
BIM not only resolves past issues related to consistency and risk in computer-generated graphics—such as plans, elevations, sections, and perspectives—but also allows the entire construction process to accumulate knowledge and avoid redundant efforts.
This type of design, implementation, and maintenance process is already common in other industries, including electronics, machinery, automotive, and aerospace sectors, where such concepts and tools have long been used for product development. Compared to these industries, the construction sector has largely remained in a “Stone Age” state, lacking continuity and accumulation during the process.
Often, repeated 3D modeling is required to reflect design changes and achieve realistic representations. Design drawings and 3D models are generated using different systems, making consistency difficult to maintain. Ensuring coherence and completeness across plans, elevations, sections, and other contract drawings remains a major challenge. Producing and approving final as-built drawings is often regarded as a difficult task by many.
Furthermore, as the building undergoes renovations and modifications over time, the importance of accurate original completion drawings grows, but their availability and reliability tend to diminish.
The BIM currently under development represents a profound transformation in architecture, comparable to an “Industrial Revolution.” It guarantees the consistency that should have been achieved, reduces construction risks, saves time and labor by preventing repeated efforts, and enables efficient, meaningful continuation and handover of activities throughout various construction stages.
This approach is incomparable to the isolated, “point-in-time” methods or tools people have traditionally relied on.
So, what exactly is BIM, and what can it do? That concludes this overview. I hope this article has been helpful to everyone!
