Although I have been involved in construction for many years, I only encountered BIM relatively recently. In October of this year, I joined a BIM training program offered by the BIM Building Training Network, approaching it with a trial-and-error mindset. I found the instructors at BIM Building Training Network to be extremely dedicated. Whether in course planning or explaining concepts, they always anticipated the students’ needs, especially for someone like me with no prior BIM experience. They explained everything thoroughly, frequently checked in on our progress, understood our requirements promptly, and adjusted the teaching content accordingly. I would like to sincerely thank all the instructors at BIM Building Training Network. Today, I want to share my insights gained from this BIM training, based on my actual work experience.
First and foremost, the most immediate benefit BIM provides is visualization—what you see is what you get. When dealing with large and complex projects, it can be challenging to picture the entire structure just from 2D drawings at first glance. However, having a 3D BIM model allows us to instantly understand the building’s appearance and get a comprehensive view of every part, including the finer details. For example, our project includes a soft film ceiling with a unique shape. Although we have 2D drawings and renderings, it’s still difficult to fully grasp its true form or explain it clearly to construction workers. Construction itself becomes especially challenging without a clear representation. But with a BIM model, it’s much simpler—we can locate this component and observe it from all angles: top, bottom, left, and right. This greatly aids construction guidance.
Secondly, BIM allows us to verify the model’s effectiveness. Using BIM, we can check whether the building’s structure meets load requirements, whether indoor radiators provide adequate heat dissipation, and if lighting fixtures meet the owner’s illumination standards. Some may think these details are minor and that issues can be fixed later if needed. However, in large projects, ignoring such checks can lead to significant material waste and extensive rework, which result in unnecessary costs.
Finally, BIM’s collision detection feature is particularly powerful. We can integrate various professional models into a single BIM model and run collision detection commands to find clashes across the entire project. This function detects both physical collisions and spacing conflicts. For example, if the distance between hot water pipes and electrical conduits must exceed 20 cm, the system will highlight any instances where this distance is less, making it easy for us to make corrections. Additionally, BIM supports both static and dynamic collision detection. For instance, if two pipes intersect only at different times, the system will not flag this as a conflict. This capability not only improves early design efficiency but also significantly reduces interdisciplinary conflicts later on. As a result, it shortens the construction timeline, lowers costs, and increases profitability.
These are my reflections on BIM after completing the training with BIM Building Training Network. Of course, my perspective is limited to the projects I manage. Regardless of how powerful BIM is, software and computers are ultimately tools—they cannot operate independently. In the end, it requires people to manage and control the process. Therefore, the successful adoption of BIM depends on everyone’s active learning, research, and exploration.
