BIM technology is applied throughout the entire lifecycle of a building, covering stages such as design, construction and acceptance, as well as operation and maintenance. When selecting BIM models, it is essential to consider the engineering characteristics alongside the economic and social benefits at each application phase.
Here are the key requirements for creating BIM models:
1. Models should consist of individual units that include both geometric and non-geometric information.
2. The model’s precision must meet the depth requirements specific to each professional discipline and project stage. Select the lowest geometric accuracy that still fulfills the application needs.
3. Models at every stage should be developed following unified rules and standards. If models are created separately by discipline or task, they must be coordinated, integrated, and compatible for combined use.
4. Model creation should use a unified coordinate system, origin, and measurement units. If a custom coordinate system is used, integration should be achieved through coordinate transformation.
5. Model elements should follow standardized classification, coding, and naming conventions. The format and naming of element information must be consistent throughout.
If any changes occur, the model, its elements, and related information should be promptly updated, with all modifications documented within the project and model records.
Throughout the BIM application process across the entire project lifecycle, all participants should establish a model sharing and exchange mechanism. This ensures efficient and reliable transfer of model data between different stages and stakeholders.
That concludes the essential requirements for creating BIM models. I hope this article has been helpful to everyone!
