To upgrade a section of the Jiuquan-Ejina Railway, China Railway First Survey and Design Institute designed the reconstruction and creation of various new assets on the 243.7-kilometer rail section. They realized that traditional methods of laying out cables would lead to disorderly cable scheduling, low engineering quality, and high risk of error. For a project of this size and complexity, amid a short timeline, the team wanted to pilot railway digital engineering technology.

Having found Autodesk solutions insufficient for the enablement of accurate design, standardized construction, and intelligent operations and maintenance, the team chose Bentley software and have since achieved significant breakthrough results. Using MicroStation to create BIM models for communication, signal, electric power, and electrification engineering helped the team to improve cable layout accuracy by 96%. Using the Bentley iTwin platform, they uniformly organized and managed data from all parties throughout the project lifecycle, increasing work efficiency by over three times and reducing material consumption by 70%.
