A tunneling engineer - not involved with this project - has questioned the use of Barn Elms as a drilling site as it would be normal procedure to put the drilling machine in at one end of tunnel and drill to the other end. Putney/Barn Elms is mid-way through one section of the tunnel that should be continuous through London Clay. This apparently changes when you get to Battersea Power station. If the above is correct, why are TW planning to dig a hole in Barn Elms? Has anybody investigated the engineering aspects of this project? |
