The project used innovative and complex numerical modelling to assess potential changes in vibration levels due to the redevelopment of Royal Mail Group buildings next to Paddington Station. The project is the demolition of buildings, and the construction of a 17-storey commercial building resting on a podium which is to be connected, via tunnels, to the Underground station.
The complex nature of the underground rail network, which includes numerous curved tunnels and trains travelling at different speeds, meant that the project presented unprecedented challenges. Cutting-edge vibration modelling techniques were used to investigate how changes to the ground conditions would affect vibration propagation, and advanced the understanding and application of those modelling techniques in the process, in order to apply them to the specific constraints and challenges posed by the project. The approach has been accepted by Westminster City Council (WCC) and can be applied to future projects to identify issues and inform mitigation measures prior to construction, allowing developers and design teams to be proactive with respect to potential vibration impacts.
