The application status and problems of intelligent site was investigated and analyzed in a large number of engineering projects. From the perspective of the actual construction site, the definition of intelligent site was proposed, and the construction plan of intelligent site was analyzed. The actual case studies and practices, which was the self-developed results of intelligent site and applied in the industry, have proved that: Firstly, In the process of intelligent site construction, by using the digital software and hardware system, construction companies are required as the main body of innovation to independently research and develop products of intelligent site that meet the own major needs and are promoted to the market, and then actively participate in the formulation of industry related standard. Seondly, The automatic collection of construction site data is the foundation and key of the intelligent site and intelligent construction, and it is also the first step and the only way to upgrade the traditional construction industry. Thirdly, The application of intelligent site can improve the quality and efficiency of the site and enterprises, and can create economic value for enterprises. It has become a new economic growth point for the construction industry.
