Concluding our first quarter updates for the Thomson Line at the Gardens by the Bay station, D-walling works on the station box continues while ground improvement work commences at entrance C beside the Marina Barrage. Nishimatsu has affirmed with us the order of a single Hitachi Zosen EPB TBM for the T228 project which will be driven across the Marina Channel. Works have yet to commence on the GBME retrieval shaft.
The cut and cover tunnel to Gardens by the Bay which have been hoarded up, now elongates the worksite boundaries of the T227 project parallel to the Marina Coastal Expressway. Deep Cement Mixing is taking place along the C&C site, in addition to the existing ground improvement works being done at the Marina South Station. Photos in this update were taken on April 14.
