From the viewing gallery levels upwards as it tapers towards its fractured peak, the Shard is a wholly steel construction. Because of the difficulties of working at (for Britain) extreme height, with winds making construction difficult and very little space to work in, this final cap section was prefabricated in 800 pieces of steel weighing almost 500 tonnes in total. Despite the use of advanced 3D modelling techniques, belt-and-braces reassurance was needed.
