On 16 February there will be a joint evening meeting between the Engineering Group of the Geological Society (EGGS) and the British Geotechnical Association (BGA). The meeting will consider the development of underground infrastructure in urban areas and the increasing requirements for innovative solutions, especially in restricted locations.
Three speakers will explore the theme using recent dewatering projects in the London Basin.
Joint evening meeting
Martin Preene will commence by summarising the issues involved and the potential impacts arising from the interaction of dewatering and urban environments. Then Toby Roberts will focus on dewatering and depressurisation strategies used to target the Lambeth Group channel sands for tunnel works in London. Finally Emilio Linde-Arias will describe a recent project in the east end of London to construct two shafts – one permanent and one temporary – to dewater the Lambeth Group and the deep aquifer from the surface and from within the shafts.
The meeting will commence at 6pm at Burlington House, with tea and coffee from 5.30pm.
