This water conservancy initiative will improve flood control capacity and the ecological environment of Changjiang New Town in Wuhan. The project presented complex terrain and strict environmental requirements, compounded by coordinating voluminous data and multiple stakeholders. Having tried several software applications to process and model the terrain data, the project team realized that they lacked the features and interoperability required to meet modeling accuracy and workflow efficiencies. The engineering firm needed a comprehensive data capture and modeling solution that supported collaboration, design, and construction. 

The team selected iTwin Capture to create a refined 3D terrain model from aerial images and analyze excavation and construction works. Bentley’s application delivered accurate modeling results and facilitated real-time information sharing, streamlining workflows to improve design precision by 30% and shorten the design cycle by 15 days. Through digital simulations, they optimized the construction scheme, reducing earthworks by 10% to minimize carbon emissions, while saving 25 days and CNY 550,000 during the construction period. The collaborative digital solution lays a solid foundation for sustainable development of the project.
