Panoramic view of the Tampines East worksite - the middle is the cut & cover portion, the right is the launch shaft. |
Excavation in the main station box has reached the second strut level and is progressing steadily with soil being removed and struts being installed as the soil level descends further. The Tampines Avenue 7 roadway above has also been diverted over the worksite to allow excavation to continue.

Additionally, nearby, there is a holding area where the second TBM shield can be seen. As mentioned earlier, this will be used once the TBM has completed its first drive to Tampines Central station where the internal components will be salvaged for the second drive while the outer layer known as the shield will be abandoned in the ground. This second shield will then be used together with the internal components to form a new TBM for the second drive.
Construction of both bounds towards Tampines Central station is expected to be completed by mid-2015.
