Abstract:In order to fully control the construction of Datengxia hydraulic project, based on the detailed analysis of the construction of Datengxia hydraulic project, and derived from the realization of various engine supports and functional modules of project management software products, the system data is interconnected. Through the BIM technology, the model is established to realize the visualization and virtualization management of the project modeling and the construction of project management system of Datengxia hydraulic project. The system provides a collaborative work platform for all departments of engineering construction management, realizes the fifilling, sending, processing of data and information as well as the collaborative sharing of business, and improves the informatization level of construction management and project investment prediction level of the Datengxia hydraulic project
