Liu noted that, dubbed a large project with high construction risks, the Guxian South railway station is an elevated platform station on the side of a viaduct line, with a construction area of 2,099.72 square meters and a building height of 11.6 meters.

To ensure the success of building the station, the CREC4 project teams prioritized work safety, adopting a more stable buckle bracket for construction, and a detailed construction plan, Liu's colleague Pu Xiao said.

Pu noted that in response to the construction difficulties of the large-span truss of the Fulaishan Station Grand Bridge, the project department optimized the support system and used digital monitoring to help the pouring of beam bodies.

"Our 24-hour dynamic monitoring points were set up on site, covering the mid span and supports, with work data being collected every two hours and any abnormal data immediately stopped for rectification," Pu said.
