Because of the continuous expansion of the project construction scale, the increasing complexity of construction technology and the continuous improvement of information management level, higher requirements are put forward for the project quality management. The traditional construction project management mode can not meet the needs of the development of modern construction projects. In view of the problems faced by construction enterprises in China, the intelligent management mode based on BIM technology is proposed, which provides a new way of thinking for the realization of construction project management. Based on the basic concepts of smart site and BIM technology, this paper discusses the specific application of intelligent site management system based on BIM technology, in order to support the decision-making of relevant managers.
