BIM, or Building Information Modeling, integrates various specialized information technologies generated throughout engineering projects. By creating a collaborative management platform based on BIM, all stakeholders can share information and manage processes more effectively, ultimately enhancing overall project management.
The construction phase of a project can be divided into three key stages: the BIM preparation stage, BIM application, and BIM model delivery. The preparation stage itself includes BIM implementation planning and BIM model establishment, as illustrated in Figure 1. BIM implementation standards are comprehensive and cover many aspects such as model information exchange protocols, color classification of models, units and coordinates, modeling foundations and standards, principles for model segmentation, file structure types, and file naming conventions. It is essential to apply all these standards thoroughly.
Currently, construction teams typically establish BIM models using one of three methods. The first and most common approach is to build the model based on the actual drawings. The second method involves rapidly generating BIM models by leveraging accumulated data from existing plugins. The third approach uses BIM models directly provided by the design team. While the second method offers high execution efficiency, it tends to be less cost-effective due to required adaptations, often resulting in significant rework. The third method is theoretically the most efficient; however, it is still in its early stages of development, and the industry has yet to adopt it widely, making practical implementation challenging. For these reasons, most construction teams currently prefer the first method.
