Research on the Efficiency Improvement Model of Construction Projects Based on the Internet of Things and Bim Technology

In this paper, a model is proposed to improve the efficiency of IOT and Building Information Modeling (BIM) techniques. First, this study uses the Internet of Things technology to achieve real-time monitoring of various equipment, materials, personnel and environment on the construction site, and uses BIM technology to manage the entire life cycle of the construction project, thereby optimizing the project decision-making process and resource allocation. The core part of the system includes an intelligent algorithm based on the combination of sensor data and BIM model, which can analyze various data in project execution in real time, adjust the construction plan and resource allocation in time, and ensure that the project is completed on time and with quality. This paper designed a variety of simulation scenarios for model testing. The simulation results show that the projects using this model have shown significant efficiency improvements in resource utilization, construction period control and cost management. The specific data analysis results show that the average project completion time is shortened by 15 %, resource waste is reduced by 20 %, and cost control accuracy is improved by 18 %.
