Lentor Excavation (II)

Excavation to the basement roof slab of the Lentor station has completed and RC works are currently prepared for the subsequent concreting. The zone 1A section that had been concreted in September has been de-strut and backfilled, which made way for a minor realignment of Lentor Loop for the remaining d-walling works to be facilitated north.

Excavation of the launch shaft has completed and the RC works for the base slab is being carried out. The pre-assembled gantry beam is present at the portal surface. Phase 1 of the subway link beneath Yio Chu Kang Road has been backfilled and the sheet piles are currently being extracted.

The project team has begun preparations for the impending second realignment of this intersection.
