In view of the complex and changeable environment during construction of waterway improvement projects，and the difficulty of information sharing and transmission between organizations，this paper uses BIM technology in the dynamic control of the waterway regulation projects to achieve the intuitive display，efficient query and sharing of engineering construction information，and thus provide scientific and necessary technical support for project dynamic decision-making，so as to better cope with the complex and changeable environment in the course of waterway regulation and ensure the realization of construction goals. Relying on the 6-meter-deep waterway regulation project in Wu’an section of the Yangtze River，the real progress，quality and investment information are associated with the modular model to achieve effective dynamic control of the three goals of the waterway improvement project.
