BIM (Building Information Modeling) has become a widely developed construction technology in advanced countries around the world. Although it has been introduced in our country for over ten years, many people still misunderstand its true meaning. Today, let’s explore what BIM really means and why it is significant.
Many people currently equate BIM with 3D CAD, believing that BIM simply stands for 3D modeling. However, there is a fundamental difference between the two. On the surface, BIM may look like 3D drawing software, but in reality, 3D modeling software is only one component of BIM. Based on the precise English terms “Information” and “Modeling,” BIM is far more than just simple 3D drawings. BIM represents a concept, a technology, and a practical application — the future direction of the construction industry.
Information: Whether using 2D or 3D CAD, engineering drawings rely on shapes, symbols, lines, and representation methods to convey engineering information. This information includes not only appearance and dimensions but also details such as material properties, color, designers, manufacturers, constructors, inspectors, dates and times, area, volume, and coding. Traditionally, 2D or 3D drawing tools could only annotate this information with text, relying heavily on experienced engineers for interpretation. This approach was prone to human error and data omissions during transmission. In contrast, BIM-compliant tools and software can embed engineering information directly into 3D models.
Modeling: Modeling is closely linked to information. It emphasizes not just the creation of a visual 3D model but also the process of integrating information into the model during its construction. Therefore, in BIM, the “M” refers not merely to the 3D model itself but to the entire process of building the model. This aspect is often misunderstood or overlooked. A well-executed modeling process enables a BIM model to retain rich information and unlock a wider range of applications.
The construction industry is one of the oldest and most traditional industries, dating back to the dawn of human civilization. All human activities depend on it, and every built environment falls within its scope. Because of its long history, the industry often struggles to move beyond legacy practices, including experience, technology, and tools. Experience must be accumulated and passed down; technology needs to be mastered and innovated; tools must be accurate and efficient. The development and application of information technology aim to meet these six goals, and BIM represents the best practice of information technology in construction.
BIM has made it easier to understand the complexities of the construction industry, no longer treating it as a “black box.” The construction sector cannot afford to fall behind in adopting information technology. We hope BIM will bring prosperity and promising prospects to the industry, making living environments more comfortable, energy-efficient, and sustainable.
That wraps up our discussion on what BIM means and its significance. I hope this article has been helpful!
