BIM informatization is characterized by the high concentration of structural project information within 3D models, project visualization through software, and the ability to coordinate and share project progress among different roles. The efficient integration and exchange of information within BIM models are widely recognized in current research. Below is a brief overview of the key characteristics of BIM:
(1) Information Integration
To enable the integration and sharing of BIM information models across different professional disciplines and various construction stages, researchers have continuously worked to merge topological relationships, 3D data, key construction process information, and attribute details among the diverse fields involved in the model. This comprehensive approach supports the sharing of structural lifecycle information effectively.
(2) Model Visualization
BIM technology features a three-dimensional environment, parametric modeling, and user-friendly viewing during model creation. These capabilities allow construction and technical professionals to view and build models in real time with clarity and intuitiveness. To facilitate interaction and collaboration among different disciplines, BIM continuously enhances related technologies by linking models with relevant professional technical data.
Furthermore, to better represent the entire lifecycle of a structure, BIM adds the time dimension to traditional 3D models, creating 4D models that integrate temporal information. This advancement plays a crucial role in evaluating construction plan feasibility and optimizing structural design.
(3) Information Synergy
In traditional CAD workflows, the lack of real-time communication among design and construction teams, coupled with software limitations, often leads to excessive consumption of manpower, time, and materials when problems arise. In contrast, BIM information models not only integrate relevant technical data across disciplines but also allow real-time modifications based on varying professional needs.
Moreover, BIM software enables intelligent linkage—when one change is made, corresponding updates automatically propagate throughout the model. This “one change triggers all” effect significantly reduces repetitive manual work and enhances overall efficiency.
(4) Information Interoperability
To overcome issues related to information transmission errors, communication barriers, and inefficient use of valuable data among different disciplines, BIM employs collaborative workflows and integrated management to facilitate seamless information exchange.
BIM technology employs IFC standards to manage project, construction, and operational data throughout the software design process. This eliminates the need for redundant data collection or the input of duplicate data in varying formats. The unified standard ensures efficient information exchange while minimizing security risks caused by errors during construction.
