Previously, there was an article written by BIM experts explaining what BIM is. Today, I want to revisit the topic, sharing my own understanding of BIM and engaging with a broader BIM community. Let’s skip the small talk and get straight to the point.
BIM stands for Building Information Modeling. In Chinese, it translates directly to the same term. Traditionally, in construction projects, architects create design drawings using software. These drawings are then passed on to structural engineers for analysis, and downstream contractors build according to those designs. Each party focuses only on their part of the process.
While this workflow may seem straightforward, it often leads to problems. Common issues include mismatches between pipeline installation and design drawings, or impractical placement of steel reinforcements. These problems arise because although architects produce the designs, structural engineers must perform computer-based analysis separately. This analysis often requires rebuilding the model using specialized software, which is time-consuming and labor-intensive.
Moreover, during this model reconstruction, discrepancies frequently occur between the new model and the original designs. This leads to inconsistencies that affect both analysis and detailed configurations. Without seamless integration, it is difficult to perfectly align all design documents. These challenges have driven the development and adoption of BIM in recent years.
The Chinese term for BIM is Building Information Modeling. It originated in the 1980s with ArchiCAD, an innovation by Graphisoft. As the name implies, BIM gradually evolved from traditional 2D drawings to comprehensive 3D models, marking a fundamental shift from earlier methods.
BIM utilizes intelligent building components such as floors, roofs, walls, windows, and doors. This advanced technology allows architects to deliver higher quality designs and integrate building information more effectively. By improving quality control and communication, BIM platforms facilitate seamless information integration.
The completed BIM model can be directly transferred to analysis software, enabling structural engineers to perform calculations without having to recreate the model. The analysis results are then sent back to the design software. This streamlined cycle not only makes it easier to access detailed building information—like coordinates and file generation—but also automates the entire process, significantly reducing human errors.
Ultimately, BIM is more than just computer graphics. It harnesses powerful computing capabilities to fully manage the entire lifecycle of a building project—including modeling, analysis, modifications, procurement, equipment management, demolition, and construction—creating a complete and integrated workflow.
This is what I wanted to share about BIM today. I encourage all BIM professionals to actively share their opinions. Individual perspectives are limited, and advancing BIM requires collective effort from everyone involved.
