Intelligent construction methods and model experiments based on digital twins

Intelligent construction has become an important direction for the development of our construction industry. How to solve the problems in traditional construction industry, such as low degree of informatization, delayed data collection and excessive reliance on construction experience for decision-making, is the key to promote the development of construction industry. In this paper, an intelligent construction method based on digital twins was presented. This method combined the Internet of things (IoT), Building Information Modeling (BIM) and finite element model to build a framework of intelligent construction based on digital twin. It also includes an intelligent decision-making platform that uses real-time monitoring data to compare with theoretical models to adjust and correct the actual construction process of physical space. Based on an example of intelligent tensioning scaled model, the method was verified by the test of spoke cable truss. The conclusion shows that the digital twin model can give real-time feedback and control the whole construction process to improve the information utilization rate in construction operations. At the same time, the intelligent decision-making can achieve the real-time monitoring, the intelligent decision-making and other functions to provide quality assurance for tension construction.
