British Tunnelling Society / Engineering Group of the Geological Society Joint Meeting Please find attached details of the forthcoming joint meeting on Engineering the Lee Tunnel and Shafts through Chalk at Depth on Wednesday 29th January 2014 (17:30 for a 18:00 start) at Burlington House, London. Currently under construction, the Thames Water Lee Tunnel will be the first section of the Thames Tideway Tunnels programme which will clean up the River Thames by capturing the combined storm water and sewage flows which presently discharge to it. The 6.9 km long, 7.2m diameter, Lee Tunnel is the deepest tunnel ever to be built in London and the project includes five shafts which are London's largest and deepest ever. These requirements have presented exceptional engineering challenges. The speakers will focus on the geotechnical and hydrogeological conditions and explain how these conditions have influenced the engineering to produce some innovative solutions. See the attached flyer for further information and details on the lecture and presenters. Please contact the convenor, Yung Loo ([log in to unmask] <mailto:[log in to unmask]> ) with any queries.
