The Thomson-East Coast Line is a future Singapore MRT system line that will connect the Thomson Line and the Eastern Region Line. The 43-km link will add 31 new stations to the existing rail network, with 7 interchange stations.

For that project, Dextra supplied numerous packages, including for example the Marine Terrace Station, where 4 large diameter soft eyes have been installed in the diaphragm wall cages in August 2017.

Soft-Eyes are made of GFRP rebar, which is used to substitute the steel reinforcement in the D-Walls of construction shafts. When the Tunnel Boring Machine (TBM) breaks through the D-Walls, it easily cuts the GFRP bars, saving time on project schedule and money on equipment usage.

Dextra has been the pioneer of this application since its first use in the Bangkok metro project in 1998 and has extensive experience for in-house design and manufacturing of Soft-Eyes.

The D-Walls installed on Terrace Station also feature Bartec® rebar couplers, a common application for most station packages in order to reconnect slabs horizontally in underground stations. Bartec couplers are also used more generally for vertical connections in foundation piles and slabs.
