A part of the Overseas Family School has completed demolishment works and earthworks and installation of bentonite silos are being done in preparations for the commencement of the diaphragm wall construction. Special care will be taken during the construction to minimize the movement of the existing NSL bored tunnels which come inches in proximity to the proposed cut and cover tunnel.
Casting works are being carried out for the slab over the launch shaft and northern section of the station box, which will employ a top-down construction method. The diaphragm wall construction continues at the southern end of the station box.
