Abstract : *(250~1000 words)

The Building information modeling (BIM) is one of the more promising developments in the architecture, engineering, and construction fields. It carries out the data management during the whole period from site analysis to later operation, and provides technical support and collaborative work platform for a built asset project. The BIM technology has five characteristics, namely, visualization, coordination, simulation, optimization and charting. With the continuous promotion of the smart city concept, BIM Technology is more and more widely used in traditional engineering fields, taking the hydraulic engineering as an instance. Based on the environmental improvement project of the Green-Water Wetland in the Nanjing reach of the Yangtze River, the BIM technology provides a fast and efficient communication platform for all partners involved in the construction period, and has been successfully and efficiently applied in the site design, model analysis, building design, and landscape design. Green-Water Wetland is located on the shoreline of the Nanjing reach of the Yangtze River. The main task of this project is to return the fishpond to the wetland, restore the forest, and improve the landscape of the whole wetland. The specific applications of BIM Technology are as follows: (1) It provides a fast and efficient communication platform for all partners involved in the construction period, and couples with the application of GIS and other digital technologies; (2) The Revit and Civil3d software was carried out to realize 3D design of the real scene, and visually display the advantages and disadvantages of each scheme; (3) The preprocessing efficiency of data was greatly improved which lay the foundation for subsequent digital analog analysis; (4) The Mars software was used to render the design scheme in real time, intuitively express the design intention, and avoid repeated design. This study is a significative attempt of BIM technology in the River shoreline project management, which has achieved social and economic benefits in the environmental improvement project of the Green-Water Wetland and shows the prominent future of this technology.
