(1) A comprehensive database can be established. The core of BIM lies in engineering data, which forms the basis for its various functionalities. This data originates from fundamental information such as geological surveys and design planning during the early stages of construction, as well as the continuous flow of information generated and updated throughout the project lifecycle. For instance, during the bidding phase, both parties must calculate extensive engineering quantities and negotiate numerous documents. Traditionally, this was done through manual errands, phone calls, emails, and other communication methods, often causing delays in information transmission and updates. When changes occur, many related parameters must be adjusted simultaneously, increasing the complexity and workload of data management. BIM technology overcomes these challenges by creating an information database that reflects all relevant data. Management personnel can collect, classify, modify, and manage this data as needed. Real-time data exchange ensures that stakeholders receive updated information promptly, enabling efficient information sharing.
(2) Models can be created to meet specific requirements. BIM technology leverages computer software systems to build models by either converting 2D drawings into 3D through BIM tools or CAD conversion, or by recognizing and transforming electronic DWG files into digital models. BIM computational models can also be developed from similar templates in the software’s built-in model library and then adapted to fit actual project needs. This approach reduces repetitive modeling efforts and improves model accuracy, making it an efficient modeling method. The resulting models can represent 3D buildings, construction processes, environments, and effects, enabling the anticipation of construction challenges and risks so that preventive measures can be taken in advance.
(3) Visualization is achieved through the integration of models and data. BIM technology allows the creation of detailed 3D models based on relevant engineering information. These models consist of multiple layers that display various building properties and their interrelations, offering a three-dimensional view of floor plans. They can also spatially illustrate the positions and relationships of components and pipelines, perform clash detection, and generate reports to optimize design. Additionally, comprehensive pipeline and structural reserve diagrams can be produced, providing a holistic view of the building that aligns closely with the actual construction. This level of visualization helps construction and management teams engage more effectively with the project.
(4) BIM enhances coordination across all project aspects. By collecting, integrating, and processing large volumes of data, BIM creates a synchronized 3D building information model that reflects the real engineering situation. This facilitates the integration and coordination of information and requirements from various departments and phases, forming a collaborative management platform. It clearly presents the work status of different disciplines and roles, strengthening communication and collaboration. Processes such as material submission, application, approval, and changes between different units become more streamlined. The design and construction teams can quickly and rationally update and confirm plans, enabling collaborative design optimization that prevents conflicts and lays a solid foundation for a smooth and coordinated project workflow.
