I began learning about BIM in 2016 and started applying it to projects at my company the same year. Over the past three years, my understanding of BIM has deepened significantly. Today, I would like to share my experience and insights into BIM technology application.
1. Human Resource Allocation: When integrating BIM into a project, it is crucial for the construction site to appoint dedicated personnel responsible for BIM-related tasks, such as a labor safety engineer. This specialized role greatly improves overall project efficiency.
2. Company Competitiveness: Building Information Modeling is an inevitable trend in the construction industry. To enhance international competitiveness, especially in China, construction companies should adopt BIM as early as possible to strengthen their capabilities.
3. Mechatronics Integration: Currently, electromechanical work is often outsourced, which can cause disputes over drawings and information. Pipeline conflicts are common. Employing a 3D approach to electromechanical engineering helps reduce these clashes. However, because electromechanical contractors typically work independently, there is often resistance to unified integration.
4. Consulting and Training: A BIM training institution in Beijing provides us with software education and training. Most trainees are involved in drafting or onsite work, so they quickly become proficient with the software and can apply it effectively to their tasks.
5. Human Resource Skills: There is currently a shortage of integrated BIM talents. Interviews with members of our BIM department revealed a strong need to improve software skills. While transitioning from 2D to 3D drawings, many tasks remain simple and repetitive, highlighting the lack of experienced, multidisciplinary professionals.

6. Construction Planning: The BIM implementation in this project lacked thorough planning at the start. Moving forward, it is essential to clearly define each participant’s responsibilities based on task complexity and manpower. Establishing a comprehensive collaborative workflow is necessary to prevent conflicts among modelers.
7. Quantity Output: Once a 3D model is established, it can directly generate material quantities. Although this project did not use quantity calculations, BIM still effectively supports material management on site.
8. Software Clash Detection: The built-in interference detection functions in BIM software help identify human errors during modeling or overlooked design issues. This feature greatly benefits designers and multidisciplinary coordination.
9. Comprehensive Discussion: Some of our projects are still in the early stages of BIM adoption and are experiencing delays, failing to shorten construction timelines as expected. For BIM to be truly effective, management practices and workflows must be aligned with BIM processes, going beyond visualization and clash detection while complying with client requirements.
Additionally, quantity calculation is a critical task since it directly impacts project costs. Accuracy in quantity takeoff influences budget estimates. Although this project lacks a procurement contract based on pre-calculated quantities, material inspection and related quantity checks are performed onsite. In the future, quantity takeoffs can be fully integrated into BIM from the bidding stage, using parametric models to automatically generate quantity reports and reduce omissions.
Currently, challenges remain in using BIM for quantity calculations. For example, because calculations rely on counting components, missing elements lead to inaccurate results. Establishing standardized verification procedures will enable more precise cost control and improved profitability through BIM-based quantity takeoffs.
That concludes my experience and insights into BIM technology application. I hope this article is helpful to everyone interested in BIM!
