ORGANIZATION

CSCEC AECOM Consultants Co., Ltd.

CSCEC AECOM Consultants Co., Ltd. is leading a RMB 460 million urban flood control and drainage project in Jinchang City, Gansu Province, China. The goal is to enhance flood resilience against a once-in-30-year storm by addressing systemic drainage deficiencies and aging pipe network data gaps. The project team, completing the work digitally with a 40% efficiency boost, utilized Bentley OpenFlows, MicroStation, and OpenRoads to build a 'Reality Model + BIM + Hydrodynamic Model' analysis system. This digital workflow reduced modeling and simulation time from months to days, accurately identifying and eliminating overflow risks—for instance, increasing a pipeline diameter on Yan'an Road to dn800 to achieve zero overflow and prevent rework. The project resolves flood risks for 1,146 hectares, protects RMB 460 million in infrastructure, and safeguards 300,000 residents. It also achieved significant sustainability gains, including a 30% reduction in earthwork excavation and an estimated 500-ton reduction in carbon emissions, providing a replicable digital benchmark for resilient northern cities.
