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.

Bright Hill Cast

Bored tunnelling works for the project were completed 2 weeks back with the docking of TBM 1 at the Upper Thomson Station, completing all 4 TBM drives under the scope of works. Preparations for the T211 tunnelling works extensively involved the challenging construction of 4 staggered launch shafts, 2 STPs, reconstruction of 2 POBs and ground improvement works beneath Block 258 at Ang Mo Kio.

Casting of the concourse slab is largely completed at the station box, with excavation works proceeding down to the platform level at certain zones. Casting of the Cross Island Line tunnels at the north end of the station box are progressing in tandem with the RC works at the concourse level. Backfilling works are underway over the completed north cut and cover tunnel structure.
