Research on Building Process Optimization Framework Based on BIM-DT

Aiming at the problems of low integration of enterprises in various parts of the construction process, low productivity, serious waste of resources, and poor construction safety, this project constructs a framework for optimizing the construction process based on BIM-DT through an in-depth analysis of the characteristics and development status of the digital twin technology and BIM technology. The framework is a complete cycle system, including data management system, BIM modeling system, and digital twin model, which are integrated with each stage of survey and design, construction preparation, construction, and operation and maintenance, respectively. Finally, in the empirical study, the construction phase is taken as the object of study, and the data management system is constructed to comprehensively demonstrate the realization process of each system, and the BP neural network is utilized for fault diagnosis.
