The judgement call
Account-gated at launchInnovative structural system: The steel-framed 'tube' structure with side-mounted cores allowed for flexible floor plates and efficient construction over the railway. - Construction over live railway: Required careful planning and execution to minimize disruption to railway operations. - Sustainable construction: Efforts to reduce embodied carbon by replacing cement with sustainable alternatives.
Key engineering challenges
Constructing a tall building over an active railway station (Liverpool Street Station). - Designing a steel-framed 'tube' structure with side-mounted cores to maximize internal space. - Achieving a long clear span (78m) over the railway lines. - Integrating double-deck elevators for efficient vertical transportation.
