The MVB consortium of Vinci Construction Grands Projets, Morgan Sindall and Bachy Soletanche has completed the 98m deep diaphragm wall for the Beckton overflow shaft − the first of the four shafts being constructed on Thames Water’s £635M Lee Tunnel project.
The 90m deep shaft, with 1.5m thick walls, is the first to be constructed for the project as it will be the launch site for the 8.88m diameter tunnel boring machine at the start of next year. The 6km long Lee Tunnel is set for completion in 2014.
