Contractors in east London last week carried out a 12 hour concrete pour as part of work to extend the 400m East India Dock Tunnel on the route of the A13 in east London. Work involved pouring 1,400m 3of concrete to form the extended roof slab for the tunnel which will extend the road underneath the A1261. A joint venture between Amec, KBR and Dragados, working for the privately financed Route Management Services, used three truck mounted concrete pumps hired from Camaud Pumps. The tunnel, originally built by Edmund Nuttall and designed by Mott MacDonald in 1992, is a twin cut and cover tunnel. The extended tunnel, currently carrying westbound traffic, will be opened to two lanes of traffic in each direction.
The extension is due to complete in September 2004. Client is Transport for London.
