The construction project aims to create a three-dimensional structure that complies with building regulations and must be accompanied by numerous illustrations within legally binding contract documents. Traditionally, these diagrams were limited by drawing tools and could only represent 3D buildings through two-dimensional drawings, requiring multiple views from different perspectives. However, this line-based method is prone to errors and can only be understood by professionally trained engineers. Currently, computers cannot automatically interpret these drawings.
BIM Technology
The emergence of Building Information Modeling (BIM) seems to offer solutions to these challenges. Today, I will discuss the background of applying BIM during the design phase.
The rapid advancement of Information Technology (IT) has enabled computers to conveniently utilize 3D tools, replacing traditional 2D representations. As a result, BIM has become a mature and widely adopted information technology in recent years. With its object-oriented programming concept and the collaborative capabilities of different professional software, BIM helps reduce many conflicts and drawing errors at the design stage.
At the construction stage, virtual construction simulations optimize scheduling and allow for pre-planning of personnel allocation, ensuring safety during hazardous work. Additionally, by linking to databases, project quantity information can be automatically extracted, improving the circulation of building information and effectively boosting efficiency within the construction industry.
However, practical applications of BIM remain limited among domestic construction companies, with many organizations yet to begin adopting this technology.
Once the design of a construction project is complete, the internal departments of construction companies must redraw the construction drawings, check for errors, correct them, and then hand the drawings over to the construction teams for on-site material calculations. The drawings undergo further checks to ensure accuracy. This process is extremely labor-intensive. Although multiple checks help reduce drawing issues, the varying skill levels of drafters often lead to new problems due to different interpretations.
The benefits of applying BIM during design can be understood from the following perspectives:
1. By converting 2D drawings into 3D models, surface issues can be identified and submitted to the construction company for correction before construction begins, helping to avoid actual losses. An effort can then be made to estimate these benefits.
2. Conflict detection can identify problems that are difficult to spot on 2D drawings. By importing various professional models for integrated analysis, conflicts can be detected early, allowing verification of the benefits gained by resolving construction issues in advance.
3. Using empirical cases, the application of BIM and its impact on changing traditional construction workflows can be evaluated, alongside the costs required to introduce BIM. This helps estimate the return on investment for construction companies adopting BIM.
4. Through case studies and practical experience, traditional tasks that BIM may replace can be explored with construction companies, culminating in a comprehensive summary of BIM workflow integration within construction firms.
This overview provides the background for applying BIM during the design stage that I wanted to share with you today. Currently, the adoption of BIM in domestic design enterprises is not ideal. The majority of companies still rely on traditional 2D design processes. However, some industry leaders have begun researching and deeply implementing BIM technology. I believe that, influenced by these pioneers, more and more design enterprises in China will start embracing the BIM application journey.
