Tunnel trouble

Civil engineering departments rushed for this month's Tunnels and Tunnelling magazine, published 바카라사이트 day after 바카라사이트 Heathrow tunnel collapse. Sadly, its printing deadlines meant that 바카라사이트 disaster was not mentioned. Instead its front-page feature was about an amazing new Austrian tunnelling technique being used for 바카라사이트 first time on London clay.
