Today, the BIM Architecture Training Network editor would like to discuss the visualization aspect of BIM technology. Although visualization is one of the key strengths of BIM Technology and clearly surpasses traditional CAD, where exactly do these advantages lie? Let me share my perspective.
The most intuitive feature of BIM is its ability to visualize design outcomes. When dealing with large and complex projects, it is often challenging to fully grasp the overall appearance of the project based solely on 2D drawings. However, with a 3D BIM model, you can instantly understand what the building will look like. You can view every part of the building from all angles, including intricate details.
For example, our project includes a soft film ceiling with a unique shape. Even though we have 2D drawings and renderings, it remains difficult to truly visualize its form or explain it clearly to construction personnel. Construction becomes especially challenging under these circumstances. But with a BIM model, it’s much simpler — you just locate the component in question and observe it from every viewpoint: above, below, left, and right. This not only aids construction guidance but also enhances communication.
If the client can see such a model before construction begins, they get a clear preview of the finished building. This allows them to identify any unreasonable or unsatisfactory aspects early on and request changes in advance. This foresight greatly reduces costly modifications later, minimizing the risk of owner dissatisfaction and cost overruns.
For example, in our current project, the main structure has already been completed and is now in the decoration phase. When the client took over the site, they found many issues and requested changes, including wall removals, alterations to ceiling construction methods, adjustments in door and window sizes, and modifications to the overall layout. These problems arose largely because the client had no clear understanding of the final building’s appearance beforehand.
In summary, by using professional software to create a three-dimensional information model for the project, we gain a virtual representation of the completed building. BIM provides visual effects and cognitive insights that 2D drawings cannot offer. At the same time, it supports effective construction planning, reduces rework, controls costs, and promotes sustainable, green, and low-carbon construction practices.
That’s all for today’s discussion on BIM technology visualization. Next time, we will explore another feature of BIM Technology — Construction Simulation. Stay tuned!
