"Geotechnical considerations and impacts on the operational railway" by Mr Neil Moss, Transport for London (TfL)

Seminar overview:
Transport infrastructure is widely believed to have developed in London because of the suitability of the London Clay as a tunnelling medium. The extensions to the original deep tube have necessitated tunnelling into the Lambeth Group soils. Although this presented challenges during construction subsequently during operations different geology driven concerns have developed. This presentation
will highlight the investigation, design and construction of the solutions.

Biography:
Mr Moss has been involved in tunnelling projects since 1989. After an eye-opening
a six-week spell at the Channel Tunnel he worked on sewage balancing tunnels in Ramsgate until the Jubilee Line Extension came along. He spent two years working on designs for Southwark Station before going on site to C102 Westminster on
