This project conducted with Graham Commercial properties entailed major paving improvements, repairs and additions.
Full project details
An iconic building
The development’s tapering shape, which when viewed from the west will appear to ‘lean away’ from St Paul’s Cathedral, delivers varied sizes of floor plates, all offering spectacular views over London. Practical completion of the shell and core is scheduled for mid-2014. The geometry of the 52-storey skyscraper makes it theoretically unstable.
Exceptional engineering skills were necessary therefore, to develop a construction methodology that enabled the building to stay upright – with tolerances of plus or minus 20mm required on all but five of its floors.
The team that was assigned to our project…were extremely professional throughout the project and assured that the owner expectations were met and often exceeded.

Logistics and DfMA
The intense public interest in the development leaves no room for logistical error. Its high-profile location – characterised by narrow and densely populated streets – along with the site’s remarkably tight footprint, represent considerable obstacles.
To work around these constraints, much of the structure – including the cores, basement and building services – will be constructed off site. However, with components of up to 26 metres in length this creates its own challenges. Once again, the team used BIM to perfect its strategy for just-in-time assembly.
