From the perspective of information technology application, the informatization development trend of engineering construction industry mainly includes: integration of enterprise management system, practicability of smart site system and implementation of BIM application; In terms of R & D, the main R & D hotspots include: 5g technology for big data automatic acquisition and transmission, big data application, artificial intelligence application, automation and robot application, etc.

1、 Integration of enterprise management system
Enterprise management system is an important part of enterprise information transformation. However, at present, the enterprise management information system is too fragmented, and the number of management systems in some enterprises even reaches more than 100, which means that there are a large number of information islands, which greatly affects the efficiency and quality of management work. It is a problem that must be solved in the digital transformation of intelligent engineering.

2、 Practical application of intelligent construction site system
The smart site means integrating application of cloud computing, big data, Internet of things, mobile Internet, AI and other Internet plus technologies, and forms a project management system. The practicability of smart site system requires the automation and real-time of a large number of data acquisition of the project. At the same time, it requires high-speed data transmission for timely response to project problems and timely decision-making of project work.
