Corkscrew Auger being use to excavate the earth, part of a process of forming steel-reinforced foundations for tall buildings. An auger is used to excavate the earth, whilst a steel sleeve is inserted to maintain the bore through the top layers of unstable ground. A steel cage or pattern of reinforcing rods is introduced into the bore before the concrete is poured. The steel sleeve is later withdrawn. These machines are being opperated by Stent, part of the Balfour Beatty Ground Engineering group. Southwark Towers was a mid rise building at 32 London Bridge Street near London Bridge station, in Southwark, London. It was 100 metres tall and had 25 floors and stood directly over London Bridge station. Completed in 1976, The building has now been demolished to make way for The Shard, which at 310 meters will be the tallest building in the United Kingdom. The piles being excavated, will form the new foundations for the Shard.
