At present, the construction industry is facing the dual challenges of labor shortage and energy conservation and environmental protection needs, and prefabricated buildings, as a new form of building industrialization, have attracted much attention because of their advantages of shortening the construction period and reducing energy consumption. However, there are obvious problems in the construction of prefabricated building projects. The project involves many parties involved in design, production, construction, etc., and the amount of information generated is huge and complex. In addition, there is a lack of uniform standards for information at all stages, from design to construction. For example, when the information of design drawings is transmitted to the component production link, misunderstandings often occur due to differences in expression forms, resulting in inconsistency between component production and design; During construction, it is also difficult to match the on-site progress and component supply information, resulting in construction stagnation or component backlog, forming information faults and islands, and seriously restricting the development speed of prefabricated buildings. Solving the problem of information sharing and transmission has become the key to promoting the development of prefabricated buildings. BIM technology provides a solution with the advantages of systematic and efficient information integration management. It integrates the whole life cycle information of the building with a 3D digital model, accurately reflects the information of prefabricated components from the design stage, helps manufacturers to produce accurately, and helps construction personnel clarify the installation process and avoid construction conflicts during the construction stage. The “14th Five-Year Plan” for the development of the construction industry clearly requires enterprises to build a BIM cloud service platform to realize the cloud transmission and sharing of BIM data, and promote the seamless connection of design, production and construction. Designers can update their plans in real time in the cloud, and all parties can access information in a timely manner. Therefore, it is of great significance to explore the use of BIM and Internet technology to realize the integrated management of prefabricated building component information, which can assist decision-making, improve efficiency, and provide reference for the industry, so as to effectively promote the development of prefabricated buildings and the sustainable progress of the construction industry.
