Stevens - RTBM Assembly

Assembly works are in progress for the second launch of the compressed-air Rectangular TBM along Whitley Road. The TBM has been reused following the successful completion of the subway structure at T221 Havelock last November. The 37-segment drive is scheduled to start next month and be completed by the end of the year, following which the TBM will be dismantled and proceed for a third run at the TELC6 T311 Bedok South project.

Diaphragm wall works for the station structure have finally completed and casting of the roof slab is ongoing along the final zone. Traffic Diversion 4 will be implemented at the station next month in preparation of the commencement of excavation works at the station.
