The Hengyang-Yongzhou Expressway is a 105.2-kilometer corridor that will improve traffic conditions and shorten travel times between the two cities, achieving industrial collaboration and better accessibility along the tourist route. Located amid prime farmland, the large-scale project presented environmental, technical, and coordination challenges among the multiple disciplines, districts, and counties. However, they realized that previous software applications lacked the compatibility and features to manage the complex, voluminous data and numerous project participants. 
 
They selected Bentley’s open, integrated 3D BIM and reality modeling applications, providing unified data compatibility to model and design the roadway alignment, minimizing impact to farmland by 10 hectares. By comparing on-site point cloud data in OpenRoads Designer, they eliminated the need for three bridges, saving CNY 40 million in costs. Through collaborative digital design and data integration, the team improved communication efficiencies by 50% and avoided 20 on-site construction errors, saving CNY 5 million. Leveraging Bentley’s BIM solutions, the project is expected to be open to traffic one year ahead of schedule.
