Earth retaining structural works for the new Orchard Station have just commenced this week. 3 machines for the D-walling are currently on the site. 2 grabs are now excavating the D-wall for the launch shaft as well as part of the station. Behind them, a hydraulic cutter is on standby to take over and excavate the rocks that will be encountered in the panel closer to the formation level.
A single Herrenknecht slurry TBM (S-963) will be launched from the shaft and execute 2 drives towards Orchard Boulevard to complete both bored tunnels. Load tests are being carried out across the station footprint, while SI and site clearing works have started in front of ION Residences.
