Design and Construction Integration Technology Based on Digital Twin

With the promotion of national policies and industrial demands, the construction industry pays more and more attention to information and intelligent development, and the progress of computer technology provides technical support for the transformation and upgrading of the construction industry. This paper introduces the application of digital twin technology in the integration of architectural design and construction. Digital twin constructs a complete virtual space mapping model by using the historical operation data and sensor data update of the physical model, so as to reflect the whole life-cycle process of the physical system. In the design stage, digital twin technology can simulate the development of the whole life cycle and feedback the data to the designers to help to decide the building performance under different parameters. In the construction stage, digital twin technology can reflect the problems in the construction, reduce the construction difficulty and improve the construction quality. In the operation and maintenance stage, more variable data are collected to reflect the internal state of the building. With the support of these data, the building condition will be analyzed and diagnosed more accurately, and the maintenance is simpler and more efficient. The application of digital twin will effectively solve the problem of low degree of digitization intelligence in the current process of design and construction integration.
