Tunnelling with Tunnel Boring Machine (TBM) technology see bright future in Korea. Government thinks TBM tunnelling is future over NATM and other methods.

In Korea press we sees more about TBM. A company we hear more is Hoban TBM division of Hoban Construction. I wrote more than one year ago Hoban TBM made agreement with German company Herrenknecht to develop Korean made Tunnel Boring Machines. Korean press (I provide link under) write 'In accordance with the agreement, Lakeshore Industries and Herenknecht agreed to cooperate with each other to manufacture equipment suitable for domestic construction conditions and ground conditions'. They also refer that agreement was signed with attendance of Hoban Industries Chairman  Jin-won Kim, Minsung Kim, Senior Vice President and also Wongil Kim, President of Hoban TBM. They write also Herrenknecht Vice Chairman Martin David Herrenknecht was there. I write this because last time truth of my my writing of this news was questioned by some people.

Also Lotte E&C improve TBM wise technbology, They write this company develop new method of constructing precast concrete (PC) panels by installing removable brackets on the bridge slab cantilever with name 'Concrete and steel bridge deck cantilever construction method using detachable brackets' (BBCM method).
