Case Study: China Railway Engineering Consulting Group Co., Ltd. achieves CNY 1.8M in construction‑management savings and a 47‑day schedule reduction with Bentley

Chongqing and Guizhou Organizations Advance Construction of Taihong Yangtze River Bridge

China Railway Engineering Consulting Group Co., Ltd. led engineering and construction management for the CNY 900 million, 1,436‑meter Taihong Yangtze River Bridge and faced a complex suspension design, difficult terrain, and fragmented paper‑based workflows. Because manual data exchange and traditional methods threatened accuracy, safety, and schedule targets, the team needed to digitalize workflows and adopt 3D BIM and reality‑modeling tools for precise surveying, simulation, and integrated information management.

Bentley delivered interoperable reality‑modeling and BIM applications — including ContextCapture, MicroStation, LumenRT, and iModels — to process UAV and laser‑scan data, build a single integrated 3D model, simulate pre‑assembly, and enable cloud‑based construction management. Using Bentley’s solutions, the project reduced design time by 300 hours (saving CNY 500,000), finished design 30 days early, cut construction management costs by nearly CNY 1.8 million, shortened construction by 47 days, and improved planning, progress monitoring, and quality control.
