5 Cross-section north– south. The external system is subdivided into eight 28m-high Megalevels, accumulating to an overall height of 224m. 6 Megaframe diagrams by ARUP describing the development of the geometric layout – they illustrate that an introduction of columns to the flank and north elevations of the building reduced the eccentricity effects of the asymmetric geometry significantly, spreading the loads more equally.
