Working in Joint Venture with Bauer secant walling is being installed as part of the completely rebuilt Tottenham Court Road tube station.
This is in preparation for the major interchange with Crossrail. Works have been underway in front of Centre Point for some 9 months and now this work can be seen by way of a time lapse video. This highly complex project in which "D" shaped piles together with plunged columns are being formed has been widely reported in the press but is now made to look very simple in Transport for London's video!
This is Keller Foundations first Crossrail Project and is proceeding on target.
Elsewhere,at Canary Wharf Keller Geotchnique have been grouting up a sheet pile cofferdam as part of the route's southern spur interchange with the DLR and Jubilee Line. Equally demanding ,this station will be beneath the North Dock in West India Docks.
For a look at dancing piling rigs and the complexities of the work......
