Utilization of sustainable BIM technology based on the Internet of Things in construction projects

Recently, China’s economy has been growing and technology has been updated and iterated. People have been thinking more and more about the traditional construction industry’s rough construction model. The traditional construction industry has a high consumption of building materials, severe environmental pollution, high engineering costs, and a lack of rationalization in construction plans. This article aimed to study how to optimize the construction process, improve efficiency, and reduce resource waste by combining Internet of Things (IoT) and Building Information Modeling (BIM) technology. This article established a construction project model that combined IoT and BIM technology (IoT + BIM) and conducted experiments to quantitatively and qualitatively evaluate the effectiveness of IoT-sustainable BIM technology in construction projects. The value of technology application was quantified by considering indicators such as construction efficiency, resource utilization efficiency, and safety. The experimental results show that the total construction time of IoT and BIM technology is 5.01 h and 5.14 h longer than that of sustainable BIM technology based on IoT, respectively; the average score of building structural safety, fire safety, and physical safety based on sustainable BIM technology based on IoT is 8.49 points; and the intelligence level is stable at more than 80%. The results of this article indicated that through the IoT and BIM technology, better planning and management can be carried out; resource waste can be avoided; design and construction efficiency can be improved; and sustainable development of construction projects can be achieved.
