2nd TBM to Soon Start Tunneling in Jaipur

Under Phase 1B of the Jaipur Metro project, the existing line is currently being extended by a distance of 2.35 kms from Chandpol station to Badi Chaupar by the CEC-CICI JV contractor. While one Tunnel Boring Machine (TBM) has already started tunneling towards Choti Chaupar, another TBM will soon be lowered into the TBM shaft at Chandpol to bore & make the parallel twin tunnel.

Note: Once construction ends in 2017  and Google updates the map, you will no longer be able to see the shaft!

In order to facilitate the start of the 2nd TBM, the first TBM will halt for a couple of days. While this isn’t the usual practice, the JMRC and CEC-CICI have decided to take it easy since many historic buildings are located in the vicinity. Once the second TBM starts tunneling, the first will resume work. As per my estimates, this extension of Line 1 will be operational by late 2017.
