The key to success in TBM tunnelling is good understanding of the geological conditions in parallel with extensive technical know-how on tunnelling construction.

 Several cases of metro TBM tunnel projects are presented to highlight how GE E&C managed difficult ground conditions (granite mixed face, alluvial, boulder bed, shale and conductive limestone) and geographical challenges (a river crossing and tunnelling below live metro, removal of existing piles/left-in temporary elements). Lessons learnt in construction and design aspects will be provided, including how it overcame obstacles in highly urbanised areas, where there was potential of settlement and damage to adjacent structures, as well as environmental issues.  In addition, GS E&C’s unique experiences in a rail test centre and multi-storey depot will be introduced.

GS E&C is the construction arm of GS Group (formerly LG) based in Seoul, S Korea. Over more than 40 years, GS E&C has delivered US$64B worth of international projects including 315 km of metro and rail lines, 186 km of tunnels, and 84 stations across Asia-Pacific and ME regions. It has completed 42 metro area projects including 25 PPPs. GS E&C ranked 28th in the 2017 ENR Top International Contractor
