The core value of BIM technology, based on its current domestic applications, can be summarized as follows:
1) Comprehensive Model Information: Beyond representing the geometric shapes and topological relationships of engineering objects, BIM includes detailed descriptions of engineering data such as object names, structural types, building materials, and various design specifications. It also covers construction processes, schedules, costs, quality control, and resources like labor, machinery, and materials. Additionally, it provides maintenance information relating to safety performance and material durability, as well as the logical relationships between engineering objects.
2) Interconnected Model Data: Objects within the information model are uniquely identifiable and linked to one another. This allows the system to analyze model data statistically and generate corresponding graphics and documentation. When an object within the model is modified, all related objects are automatically updated to maintain the model’s integrity and robustness.
3) Consistency of Model Information: BIM ensures that model data remains consistent throughout the different stages of a building’s lifecycle, eliminating the need for redundant data entry. The information model can evolve automatically, enabling easy modifications and expansions at various stages without the need for complete re-creation. This helps avoid errors caused by inconsistent data. BIM supports professionals across design, construction, and cost estimation disciplines through simulation and analysis, providing a collaborative platform based on 3D digital models. This integrated approach enhances project design, construction, and operation management, ultimately driving energy savings, cost reductions, and efficiency improvements throughout all phases of the project.
