Research on the Information Integration Model of Prefabricated Buildings Based on BIM Technology

This paper constructs a multi-dimensional information integration framework based on building information modeling (BIM) technology, aiming to integrate data flows at all stages of the building life cycle and realize efficient information sharing and collaborative management. The framework adopts an improved semantic integration algorithm, and by optimizing data matching rules and semantic parsing models, it effectively improves the compatibility and interaction efficiency between heterogeneous data sources, and solves the problems of data islands, semantic conflicts and inefficiency in the traditional information integration process. In order to verify the actual application effect of the framework, an actual prefabricated building project was selected as a case, and performance tests were carried out in the design data interaction, construction plan integration and operation and maintenance information sharing links. The simulation results show that the framework significantly improves the data interaction speed and the information integration efficiency by about 28%. At the same time, it ensures the consistency of key node data, and the error rate is controlled within 1.5%. In addition, the experiment also shows that in the multi-stage collaborative work scenario, the framework has high stability and scalability, providing an efficient information management solution for prefabricated building projects.
