    Application of BIM Strategy for Dali to Ruili Railway Project

    Baoshan, Yunnan, China

Project Summary

The 330-kilometer Dali-Ruili Railway, which is currently under construction in China’s Yunnan province, will include the world’s longest span bridge, the Nujiang Four-Line Bridge stretching more than 1,024.2 meters, and the Gaoligong Mountain Tunnel, Asia’s longest at 34.5 kilometers. The China Railway Eryuan Engineering Group, Yungui Railway Yunnan Co. Ltd., China Railway 18 Bureau Group Co. Ltd., and China Railway Tunnel Group Co. Ltd. were tasked with implementing a comprehensive 3D BIM approach for this complex project. The team faced terrain challenges, geological constraints, complex structural design, and routing.

The team used Bentley’s BIM applications to develop complex 3D models of the geology, bridges, and tunnels. It also had to integrate the information required by the Chinese Railway standards and create a construction management platform based on the BIM technology, which was used to effectively manage the quality, safety, investment, and progress of the railway’s construction.

The team improved design efficiency by nearly 100 times, shortened the design period by 1,000 hours, and saved labor costs equivalent to more than 20 people on the project using Bentley applications. OpenRoads technology in PowerCivil for China was used to model the routing for the railway tunnel, while ProStructures was used for the steel truss arch bridge, and MicroStation to model the terrain and foundations. ProjectWise streamlined workflows and enhanced collaboration, enabling delivery of the project 100 days ahead of schedule.

Using ProjectWise as its collaborative design platform, the team efficiently operationalized a comprehensive BIM workflow. Setting appropriate permissions for the different users involved, its adoption of a common data format facilitated information sharing across different disciplines and phases. The design, construction, and supervision parties, as well as the owner, used Bentley software to support its BIM construction management platform, making it easy to understand project progress, investments, safety, and quality.
