Tunnelling 10M below the City of London.

Deep below the high-rise structure of the city of London are ancient sewers and the tube network. When a collapsed sewer occurs at such a depth then a very special deep shaft and tunnelling solution is required. M J Rooney converted half of the basement into a sewage pumping store to allow the offices to carry on as usual and built a 10m deep steel lined shaft from within the other half of the basement. From there a tunnel was driven with steel lining and support structure to locate the collapsed section of line directly beside the underground tunnel.
