Introduction With the appearance of new materials and advanced technology, modern construction projects have become more and more complex, especially the metro project that have the characteristics of large investment, long construction period, involving a wide range of participants and heavy workload of information processing.
BIM integrated construction information on a variety of engineering data model and detailed information of digital expression related to the project.
BIM building information model is not a computer modeling used in rendering or animation in AutoCAD, but a model database contains many additional engineering information and stores all the architectural design involving all the geometric information and the corresponding engineering and technical information.
The inevitable engineering change of the project can be promptly reflected in the model, and automatically calculate how much the engineering change affect on cost, schedule and construction drawings
