Abstract: Aiming at the inadequate information exchange and sharing and the backward project management,we proposed to apply BIM (Building Information Modeling) technology to concrete dam construction management. We built an information model for concrete dam construction and developed a system which had functions of multi-dimensional information integration,information exchange and sharing,and real-time monitoring of engineering resource and cost. The research provides support for the management of concrete dam construction information. An example of a concrete dam is given to verify the practicability and advantage of this technology.

Key words: hydraulic engineering, BIM, concrete dam, construction management
