Shenton Way D-walls (III)

The diaphragm wall for the Shenton Way station is nearly completed and excavation works are slated to commence by the beginning of next year. Grouting is taking place across the station box. The diversion of the monsoon drain across the central linear park has also been completed.

The tunnel drives for this project have been altered from the initial A/E consultant specifications. Each TBM will now complete the respective upper and lower drives between 2 stations as opposed to completing the tunnels to Maxwell first, before relaunching both machines at Marina Bay.

Marina Bay - Shenton Way Tunnels
Excavation of the launch shaft at Marina Bay is completed and the first STEC EPB TBM is slated to arrive at the site upon handover from Taisei around the first quarter of 2016. Mining of the lower Woodlands bound tunnel should commence by the 2nd quarter thereafter. As of now, ground improvement works continue to take place along the tunnel route beside the Marina One project. Updates on the launch shaft at Marina Bay can be found here.

Shenton Way - Maxwell Tunnels
A section of McCallum St between Boon Tat Link and Robinson Road was closed on September 6 as the project team continues the advanced preparatory works ahead of the TBM launch. An access shaft will be constructed beneath the road to facilitate protection works to the adjacent operational EWL tunnels beneath Robinson Road. The road will reopen by the 4th quarter of 2016 - around the time when the second TBM is expected to launch.
