Upper Thomson D-walls (III)

The diaphragm wall along the north wall has completed and the 2nd stage of traffic diversion is being implemented in phases, after which the d-walling works would continue along the center of the road. The road realignments are facilitated in tandem with the phase-by-phase construction of the new canal, which will sit on the roof of the Upper Thomson station box.

Backfilling of the constructed canal

Upper Thomson Launch Shaft

Casting of the base slab of the launch shaft is in progress. The STP has been fully assembled and the TBM is anticipated to arrive by next month. There is a slight delay in the project here due to the longer duration in the preparations of the road diversion last year. Tunnelling works should only commence at the start of Q2 2016.
