Tunnelling breakthrough for Chennai metro

Chennai Metro Rail’s (CMR’s) tunnel boring machine (TBM) has reached breakthrough at AG-DMS station, marking the completion of the bulk of the tunnelling works on the project.

The tunnelling work commenced at Saidapet Ramp and involved a total drive length of 3.3km.

The machine is the second TBM on the project to breakthrough at AG-DMS station, with both TBMs passing through two underground stations at Nandanam and Teynampet.

In June it was revealed that tunnelling contractor Mosmetrostroy had abandoned the scheme. Work was delayed for six weeks, before CMR brought in Afcons to restart the work.

Phase 1 of the metro project is scheduled for completion in 2016.
