The Dongtaizi Reservoir project is a large-scale water conservancy initiative scheduled as part of China’s 13th Five-year Plan period. Liaoning Water Conservancy and Hydropower Survey and Design Research Institute is the engineering, survey, and design unit and faced technical, geological, and coordination challenges. They realized that traditional design methods were insufficient and that they needed an integrated 3D BIM approach to accommodate the geology, excavation, and dam design.

The team used ProjectWise as the collaborative design management platform, providing a connected data environment for the multiple disciplines. OpenBuildings and OpenRoads facilitated 3D modeling and visualization that helped resolve difficulties designing the ecological fishway and complex concrete dam structure. Using Bentley’s integrated applications, they completed the engineering design two weeks earlier than expected and reduced design errors by 90%. The digital models were handed over for construction monitoring, operations, and maintenance to achieve full-lifecycle BIM application.
