In view of the problems in the construction process of large group engineering projects, such as large engineering volume, difficult personnel management, complex comprehensive pipe network, multiple cross-operation surfaces, and difficult construction management, the application research of smart site is carried out based on the engineering example of Qingdao International Academician Port comprehensive supporting project, and the application advantages of digital, intelligent and precise management are excavated. The results show that the application of smart site in production management, personnel management, special equipment management, safety management, material management, environmental management and other aspects can effectively improve the construction safety, quality, schedule and cost control information management level, smart site to promote the transformation and upgrading of residential construction to smart.
