Stevens D-walls (III)

D-walling works continue at the Stevens station, with a partial realignment of the northbound carriageway in November for the construction of the diaphragm wall in the center of the road. Piling works continue for the pipe jacking machine launching shaft at SCGS.

Over at the Mount Pleasant launch shaft, the Changi-bound TBM has completed assembly within the shaft and is likely in the midst of finalizing the electrical components - resulting in a delay faced by its sister machines at T208. The Woodlands-bound TBM is in the process of assembly at the completed Dalvey launch shaft.
