BIM Technology For Efficient Design Of Chinese Railway
The Dali to Ruili railway is a single-track
passenger and freight railway being
constructed at a total cost of CNY 25.7 billion
in the Yunnan province of Southwest China.
The China Railway Eryuan Engineering Group
Co. Ltd., established as a subsidiary to China
Railway Group Limited in 1952, is responsible
for design and 3D modelling of the 330km
project. Using Bentley’s BIM technology, the
design team greatly improved design efficiency
and shortened the design time by 1,000 hours.
Moreover, using this technology provided
the foundation for future 3D design and
digitalization of the Chinese railway.
The line, which forms the western route of China’s rail link with Southeast Asia and is part of the Trans-Asian Railway, includes the Nujiang Bridge and Gaoligong Mountain Tunnel, after completion will represent the world’s longest span for a railway arch bridge and longest railway tunnel in Asia. Facing collaboration and coordination challenges among disciplines with its existing technology, the project group conducted extensive research and development of all available software and chose to adopt Bentley’s technology to achieve the following outcomes:
- Complex route investigation and definition for the Gaoligong Mountain Tunnel
- Transfer via IFC to achieve standardized Chinese Railway components
- Improved modelling efficiency for geology, tunnels, and bridges
- Efficient control of design changes including the Gaoligong Mountain Tunnel
- Transfer of the 3D BIM design model to construction management
Responsible for the implementation of BIM advancements on the project, China Railway Eryuan Engineering Group Co. Ltd. used Bentley’s comprehensive modelling and common data environments to manage all the information required by Chinese Railway standards and deliver effective and efficient collaboration for all the disciplines and users involved. By using the Bentley platform, the 3D collaborative design of the whole project was completed efficiently and rapidly, which brought hope and confidence for our future intelligent railway construction, said Fengxiang Dong, Director of BIM Center, China Railway Eryuan Engineering Group Co., Ltd.
