BIM model types can be categorized into overall models for each project stage, specialized sub-models, and specific models tailored to different needs.
Because BIM models store numerous files at various stages and contain vast amounts of data, they demand high-performance computer systems. Additionally, participants from different phases and disciplines require a clear understanding of these files and often need to transfer and share information across various collaborative management platforms. Therefore, proper file naming conventions and lightweight processing are fundamental throughout the BIM workflow. These practices are essential for lossless information transmission and effective data sharing.
File naming rules in BIM models form the foundation for smooth information display and sharing. Typically, naming conventions are chosen based on national standards, practical application needs, industry habits, and other factors relevant to each project stage. These conventions remain consistent throughout each stage to ensure information is transmitted without loss and that BIM model data remains complete and unified.
Naming principles for BIM models can be organized by project stage, progress, discipline, and special purpose to avoid conflicts and confusion with existing engineering domain names. For instance:
- By stage: survey and design model, schematic design model, preliminary design model, construction drawing design model, detailed construction design model, production and manufacturing model, completion model, and operation and maintenance model.
- By discipline: architectural models, structural models, mechanical and electrical models, equipment models, curtain wall models, and other specialized models.
- By special purpose: site models, performance analysis models, construction site planning models, construction process simulation models, schedule management models, construction equipment and material management models, prefabricated component processing models, construction drawing design budget models, construction process cost management models, digital acceptance models, and completion settlement models.
The BIM lightweight engine addresses the integration between BIM models and software systems beyond traditional modeling tools. It bridges the gap for platform software—such as project management systems, monitoring systems, and office automation systems—on web and mobile platforms. This enables the use of BIM models across various applications without the need to install professional modeling software like Revit, Navisworks, or Bentley.
