The Nanyanjiang Intercity Railway project is the first high-speed railway project in China that adopts a large-scale, 40-meter simply supported box girder. CCCC Third Harbor Engineering undertook construction of the 33.9-kilometer line, consisting of five large bridges and one station. They had to manage a multidiscipline team, compounded by existing infrastructure that restricted construction and presented safety risks. When third-party modeling software proved incapable of building the complicated models, they sought to enable integrated modeling and digital management.

They selected ContextCapture to build a reality mesh, helping to make use of the limited construction space. Using OpenBridge Modeler to build more than 10,000 models improved modeling efficiency and accuracy, identifying errors in advance. ProjectWise provided a collaborative management platform, while SYNCHRO 4D facilitated dynamic schedule management, reducing construction by 130 days. Bentley’s integrated digital applications provided a new mode of digital management, setting a benchmark for digital transformation in construction.
