    Phase III Project of South Highway Connecting Line of Jinsha River Highway-Railway Bridge

    Yibin, Sichuan, China

Project Summary


Phase III of the South Highway Connecting Line for the Jinsha River Highway-Railway Bridge in Yibin, China, involved the design of a 1,440-meter urban expressway from Jinshajiang Road to Yiqing Road. The over CNY 408 million project included a roadway with six lanes in each direction, two interchanges, and a 765-meter overbridge. China CMCU Engineering (CMCU) was tasked with the design of the Jinshajiang interchange and its six ramps, an interconnected bridge, and an over-bridge. With a multi-discipline design team to handle routing, bridges, and drainage, CMCU required a collaborative BIM solution to optimize information sharing and design quality.



CMCU used Bentley’s integrated modeling technology to implement a BIM methodology for the first time on a municipal roadway project. To achieve a collaborative, efficient design, the team worked in a unified design environment using PowerCivil for China, MicroStation, and Bentley Navigator, with ProjectWise as the common platform for data storage and information sharing. Using Bentley LumenRT, CMCU vividly demonstrated the design concept for each segment. Bentley’s interoperable BIM advancements ensured accurate integration of multi-discipline models and data integrity throughout the project for an optimal design solution.



Bentley applications provided CMCU the design and visualization technology to help intuitively solve complex engineering problems, improving design quality while saving time and resources. The software automated design adjustments and calculations to accommodate different design parameters and constraints, reducing redundant design work by 40 percent and saving an estimated CNY 300,000 in costs. Using Bentley software optimized information sharing and optioneering throughout the design process to save 15 work days and reduce overall communication costs.



Using ProjectWise, MicroStation, and Bentley Navigator supported synergetic design among the multi-discipline design team, enhancing design quality and efficiency. Navigator enabled the team to quickly identify collision points and detect abnormalities during the design stage, while Bentley Subsurface Utility Engineering (SUE) was instrumental in drainage design. The team used PowerCivil for China to create more than 15 multi-visual 3D cutaway display drawings and generated 3D fly-through videos using Bentley LumenRT to vividly demonstrate the design concept.


  • ProjectWise, MicroStation, PowerCivil for China, and Bentley Navigator supported synergetic design and clash detection, improving design quality and efficiency.
  • The team used Bentley LumenRT to render real-time visualizations demonstrating the design concept for each segment throughout the project.
  • Bentley’s integrated modeling applications optimized collaboration and reduced rework by 40 percent, saving CNY 300,000 in costs.
  • The CNY 408 million project required CMCU to coordinate the multi-discipline design of the Jinshajiang interchange, including six ramps, an interconnected bridge, and overbridge, as part of Phase III of the South Highway Connecting Line for the Jinsha River Highway-Railway Bridge in Yibin, China.
  • “Collaborative application of Bentley [software] speeds up design of municipal projects and improves efficiency.”
