Along with the continuous blowout development of information technology in China, the big data, intelligence, cloud computing, mobile internet technology, IoT(Internet of Things)technology, and etc. have already become the characteristics of the new era of information technology. By applying the above technologies is able to change the traditional management mode of the construction industry and to realize the informatization based on the engineering construction, which has already become a major trend of the industry development. Taking the Shenzhen International Convention & Exhibition Center(phase I)project as an example, this paper introduces in details how to establish a refined system for information collaborative management and data integration management involving with the key elements such as human, machine, material, law and environment in large-scaled engineering projects. The application of the BIM technology, mobile internet technology, IoT technology and other information technologies will contribute to improve the quality, safety and progress control in the process of project construction, and to enhance the production efficiency, management efficiency and decision-making ability of the construction site, which will finally achieve the goals of efficient collaboration, refined and intelligent production and management.
