SINGAPORE: Tunnelling works for the Bayfront MRT station
which is linked to integrated resort Marina Bay Sands have been
completed.
The 620-metre tunnel will connect the Integrated Resort with
Promenade MRT Station, located along Temasek Avenue near Suntec
City.
It is the first completed tunnel in Downtown Line One.
To speed up the excavation work, a 75-metre tall Tunnel Boring
Machine (TBM) was used.
The six stations of Downtown Line One are scheduled to open in
2013.
Poh Chee Keng, senior project engineer, Downtown Line 1, said:
"Factors that we consider are - the duration that we have to
complete the job and the length of the tunnel. For example, if we
use the TBM method, we take about three months. But if we use the
manual excavation, we take about fourteen months."
