Mobilisation starts at Blackfriars under the Thames Tideway Project

Robert West is proud to be part of the Thames Tideway Tunnel Project.


Our client, Ferrovial – Laing O’Rourke JV, is already mobilizing the construction barges and jack-up platforms at Blackfriars where one of the main shafts will be built.  For this purpose, a cofferdam wall will be built extending for 150m and upstream of the Blackfriars Bridge. This will allow undertaking the excavation works and construction of the permanent concrete culvert that will connect with the local rainfall overflow outlet.

Robert West acted as main designers of the cofferdam structure.  This involved assessing possible alternatives by undertaking:

  • ship impact/push-over analysis
  • temporary culvert floatation analysis
  • auxiliary structures and earth works for piling activities
  • overall structural design.
  • Committed
  • Engaging
  • Professional
  • Confident
  • Adaptable
