The SG5 project of the Beijing-Xiong’an Highway is a 6.83-kilometer expressway featuring the construction of two large-scale bridges that comprise 99.5% of the entire route. The project is a key provincial highway located along arable land that is surrounded by populous villages and dense pipeline networks, facing a tight timeline and strict environmental protection requirements. To address these challenges, CCCC Third Highway Engineering needed advanced BIM technology to establish a collaborative digital modeling and construction management platform.

Already familiar with Bentley applications, they selected MicroStation and OpenRoads Designer to create a 3D component library for parametric modeling of the bridge structures and establish a connected data environment for sharing data and models among the multiple disciplines. Working in a digitally coordinated platform, they modeled the 5,040-meter Langouwa Bridge in three days. Through visual construction management, they shortened the construction period by 90 days, reduced material waste by 30%, and saved CNY 15 million in costs.
