Abstract: In recent years, with the improvement of BIM technology application level, the integration of BIM and information technology in the construction industry has become increasingly close, and the engineering construction management level are constantly improving. Under the guidance of a series of national policies, "strive to enhance the integrated application capabilities of BIM, big data, intelligence, mobile communication, cloud computing, Internet of things and other information technologies" has promoted the development goal of the informatization level of the construction industry to a new level. All localities have responded and published supporting work implementation documents. BIM 3D review, CIM, smart city, etc, also in continusous development around the construction industry. In this paper, the application value of BIM technology in three-dimensional collaborative design, visual analysis, professional design deepening, data fusion and BIM collaborative platform management in campus construction projects will be elaborated in detail by taking the whole process integration application of BIM design in Guangzhou experimental middle school project of Sino-Singapore Guangzhou Knowledge City as an example. The analysis and exploration of the application of BIM technology in three-dimensional review, BIM development and BIM + smart campus and provides valuable experience for BIM design integration application method and process in the process of smart campus and follow-up project construction process.
