The conceptual theory of Building Information Modeling (BIM) technology originated in the United States. Essentially, BIM represents data-driven, three-dimensional modeling. According to the 2016 Chinese industry standard, the Unified Standard for Building Information Modeling Application (JG/T51212-2016), BIM technology is defined as “a comprehensive term describing the process and results of digitizing the physical and functional characteristics of construction projects and facilities throughout their entire lifecycle, encompassing design, construction, and operation.”
BIM technology addresses the limitations of traditional design methods by utilizing Autodesk Revit software, which transforms conventional 2D drawings into detailed 3D architectural information models. Unlike CAD’s focus on points and lines, Revit builds models using various building components and families as fundamental elements. Because these models are information-rich, parameters are added to each component, integrating the physical model with comprehensive data.
This approach allows BIM to effectively analyze natural factors such as acoustics, lighting, thermal performance, and airflow within buildings. With the rise of green building practices and ecological awareness, traditional design methods often evaluate energy consumption only after the design phase is complete, causing delays and increasing costs due to necessary revisions. In contrast, BIM enables real-time performance simulations that assess building-related digital information, allowing timely optimization during the design process.
Furthermore, BIM facilitates collaboration among various design professionals using the same building model, improving coordination and reducing conflicts between different disciplines. Revit’s 3D visualization and full lifecycle data capabilities support proactive design improvements, driving the advancement of BIM technology, as illustrated in Figure 1.
