The traditional construction industry is still in the labor-intensive stage and consumes a lot of social resources, especially the energy consumption of buildings and the production process of building materials. The total energy consumption in the society accounts for 46%, which has become a huge burden on the national economy. It is imperative to develop green, low-carbon and environment-friendly industries. The advanced construction technology based on information physical system (CPS) and the deep integration of information technology emerge at the historic moment, the intelligent construction system can effectively solve the above problems, and it is also the inevitable trend of the transformation and upgrading of the construction industry. Build efficient intelligent building system need to organic integration of artificial intelligence, 3 d printing, digital manufacturing, robotics, big data, Internet of things and cloud computing and other advanced technology, to ensure that the buildings in the whole life cycle in different stages of the whole chain, various professional and coordination between the parties, realization of physical space and virtual space bring out the best in each other, in order to realize the construction mode of production to upgrade and boost productivity.

Most of the architectural and structural design in the traditional building industry is still manually designed for a single project, which requires designers to carry out a lot of repetitive work. In particular, due to the reason of material saving, the size of components and accessories are different, and the difficulty and efficiency of industrialization, intelligence and construction process management are increased. The basic technical characteristics of intelligent construction are intelligent planning and design, automatic processing and production, intelligent assembly of on-site construction, informatization of operation and maintenance management, and resource-based demolition of waste parts. To ensure the quality of construction, construction efficiency, reduce labor demand, while achieving the life cycle maintenance of the building. Systematization of structural design, modularization and standardization of structural components and supporting parts are the basis and efficiency guarantee for realizing intelligent architectural design. In addition, efficient structural system and connection node technology are one of the key technologies to realize intelligent design, and the development level of related technologies is an important indicator to measure the level of a country's intelligent construction industry.

Intelligent building physics is based on the information System of CPS depth fusion, advanced construction technology and information technology in industrial building and built on the basis of digital, based on the architecture and component, a ministry of infrastructure and System (namely Physical System, Physical System or entity) in the whole life cycle of the project, design, manufacture, transportation, construction of the assembly, operations and services activities through cyberspace (i.e., Cyber System) twin model perception and analysis of information, data mining and modeling, status review and anticipation, intelligent optimization and decision-making, So as to realize the knowledge reasoning, intelligent sensing and precise control and execution of the construction object itself, the construction process, the construction equipment and the construction system. The intelligent construction system includes three subsystems: intelligent design and planning, intelligent equipment and construction, and intelligent operation and maintenance and service, involving advanced technologies such as artificial intelligence, 3D printing, digital construction, robotics, big data, Internet of things and cloud computing. With the further development of building industrialization, construction productivity increasingly rely on cross administered, and further derived emerging interdisciplinary such as intelligent building, intelligent building system only through building, civil, computer, mechanical, telecom, materials, management and the depth of the multi-disciplinary cross research can be implemented, and related research to the university of technology system, joint innovation mechanism between the enterprise and the ability to put forward higher requirements.
