Aiming at the problem of traditional project information management system,such as singleness means,information dispersion,poor synergetic efficiency,difficulty in decision support,heavy investment in maintenance updates,we research the project management platform based on BIM technology.We use cloud and heterogeneous system integration technology to make a private cloud deployment and heterogeneous system integration,which ensures the regional coordination office from different users and the circulation of BIM information between different systems,realizes the deep integration of BIM model,GIS environment and the project management system.The results show that the BIM project management platform effectively reduces the enterprise hardware and software maintenance costs,and innovates management tool and process in progress simulation,quality traceability,safety monitoring,investment control.The BIM project management platform can improve the project management efficiency and level.
