Project Complete 2014
This 224m high, 50 storey office building in the City of London provides 56,000m² of office accommodation, and features a distinctive external steel braced ‘megaframe’ stability structure – a first for a building of this height – and extensive architectural steelwork detailing. Popularly known as the ‘Cheesegrater’ due to its distinctive wedge shape, this shape causes the building to naturally lean to the north. Catherine carried out complex structural analysis in order to assess the magnitude of this effect to facilitate the ‘Active Alignment’ technique employed to compensate. The process involved adjusting the lean of the building at every ‘megalevel’ by either removing or adding in packing pieces where the nodes meet the columns.
