Project description

A vast and complex infrastructure project consisting of two commercial towers and a metro station. Above and below ground, the design resolved complex structural challenges, threading column loads between existing and new tunnels and creating a 30m deep, naturally lit basement atrium to enhance wayfinding and passenger experience. Strong temporary works and innovative stability systems supported the safe delivery of five basement levels and new concourses.
