 In addition, excavation seems to be progressing pretty well overall.

C922 - Expo station has already reached the base slab level at portions of the station.

C925 - Tampines East station is in the process of constructing the retaining walls. The TBM was lowered within the last month and assembled at the launch shaft ready for the Expo-bound drive to Tampines Central station.

C926 - Tampines West is still in the process of constructing the retaining walls as the Tampines Avenue 4 was only shifted over the completed portion a few months ago.

C928 - Bedok North has excavated most of the soil from the station pit area. They will be progressing onto the structural works soon.

C929 - Kaki Bukit station has the top layer casted and excavation work is progressing below using the top-down method where the permanent structure is cast before moving lower to commence excavation at the preceding level below.

C933 - Bendemeer station has seen some under-platform level work go on. Concrete pouring has also been taking place.

 C935 - Jalan Besar station is also employing the top-down method of construction. Most areas have progressed to level 2 of excavation.

C937 - Fort Canning station is progressing swiftly with the top-down method as well. Excavation continues on.
