(1) Naming Conventions for Models: As models become more complex and design revisions increase, the number of BIM models and backup files multiplies. To efficiently distinguish models by discipline, region, and creation date—and to reduce the time spent locating specific files—it is essential to implement a consistent naming convention throughout the modeling process.
(2) Model Depth Control: Different project phases require varying levels of BIM model detail. For instance, during the architectural design phase, it’s sufficient to understand the building’s appearance and overall layout. However, in the construction phase, detailed information such as component size, material, and cost is necessary for quantity takeoff and process management. Therefore, model depth should be tailored to the specific demands of each project stage.
(3) Model Quality Control: High-quality BIM models are crucial for effective visualization and construction guidance. Both these applications demand strict quality management to maximize the benefits of BIM technology and provide reliable support during construction.
(4) Model Accuracy Control: BIM models rely on computer technology to visually represent buildings accurately. Ensuring precise dimensions and building heights is critical, as it forms the basis for subsequent building analysis and construction control.
(5) Model Integrity Control: Model integrity encompasses two key aspects: accuracy and depth. Accuracy refers to the physical representation of the model, often measured by Level of Detail (LOD). Depth relates to the functional information embedded within the model. Accurate models fully represent all floors and disciplines, while the depth includes construction-phase data and component-specific information that supports various downstream applications.
(6) Model Size Control: As multiple stakeholders contribute information, BIM model files grow in size, increasing virtual memory demands. Large files can exceed hard disk read/write capabilities, leading to software crashes. To prevent this, model files must be strictly controlled; once a file exceeds 200MB, it should be split to reduce the computer’s processing load.
(7) Model Delivery Rules: Delivering the BIM model finalizes the transfer of building information. It is important to organize delivery documents carefully to ensure that all building information is accurately and completely transmitted.
