Abstract: Developing construction industry Internet is one of the primary tasks of implementing intelligent construction and construction industrialization, which brings new support for the high-quality development of the construction industry. Supporting the demand for all factors, all processes, and whole industry chain connections, as well as the complex structure of multi-discipline and multi-system intersection put forward higher requirements for establishing a unified system architecture. On the basis of the existing research, this paper summarizes the concept of the construction industry Internet, elaborates the advantages of various industrial Internet architectures, and establishes a new type service-oriented construction industry Internet system architecture supported by construction and information technologies, which can integrate implementation, capability, and platform, and may be applied to guide technological innovation, promote enterprise exploration, and provide theoretical support for the development of construction industry Internet.
