Design and BIM-based technology on a new cross-sea bridge in Xiamen, China

The Xiamen Second East Cross-Sea Bridge in China is a continuous steel box-girder bridge completed in September 2022. Innovative design and construction technologies helped to improve design, delivery and long-term performance. Building information models were extended from design and construction process simulation to systems for safety, quality management, monitoring and maintenance. This paper describes how whole life-cycle digital modelling significantly improved project management, construction quality and overall costs.
