(NSL) Ang Mo Kio station.

Over Q3, works have progressed at the Ang Mo Kio station site. Significant progress has been made at the launch shaft site as well as several exit worksites where diaphragm wall excavation works have commenced. Soil treatment work is also being carried out at Exit 8 ahead of excavation there.

Launch shaft
The launch shaft capping beam has since been prepared. Over the past quarter, the launch shaft has been concealed with an acoustic shed that will help to keep noise levels minimised to limit disturbance to surrounding residents in the area.
