A complex shape
The rail level, 25m below ground, will be contained within a concrete box 454m long and 52m wide, intersected by train tunnels at the north and south ends and connected to the ticket zone at mezzanine level and the ground floor concourse by a system of escalators, travelators and lifts.
Above the station is a roof that consists of a 450m long steel structure defined by a cylindrical surface formed by a steel diagrid structure.
The structural scheme shapes a wide open spaces with large voids in plan that allow daylight penetration to platform level.
The complex shape of the structures along with the quality of the exposed concrete will be crucial to the architectural appearance of this part of the project.
