Tampines West progress

Tampines West station has only begun excavation work recently, unlike its counterpart and twin station Tampines East, which has already begun casting the station structure. The ground on which the station is sited is made of sand though, which can explain the slower progress to ensure minimal movement of the neighbouring HDB block. However, the saving grace is that sand is easier to excavate than harder granite so excavation can be done pretty quickly. Like its sister station, Tampines West was also planned with 4 exits although only 2 have been approved for construction.
