With a major boom in infrastructure development including transport infrastructure to help with traffic decongestion, the urban development authority is focusing more on the expansion of underground infrastructure. Specifically, the focus has been placed on the construction of a metro rail system to meet the large demand for efficient means of transport. In order to expedite the construction work and with minimal inconvenience to the public, large numbers of TBMs are being deployed to carry out the underground construction work, which had contributed to the growth of the TBM market.
