Terratec wins contracts for Pune Metro

2 May 2019

India - Terratec has secured two contracts for Pune metro rail in Maharashtra, India. A number of 6.61m diameter EPB TBMs (EPBMs) will be delivered to the 16.56km-long Line 1 of the new metro. The precise number of machines is still being finalised by the contractor and client, according to Terratec.

Last February Maharashtra Metro Rail Corporation Limited’s (MMRCL) executive director Atul Gadgil announced that the joint venture between Gulermak and Tata Projects Limited had won both of the twin tube tunnel packages on the north-south corridor.

The 5km underground section of the Line 1 corridor is the most challenging part as it passes through some urban areas like Kasba Peth, Budhwar Peth and Mandai market.

The EPBMs will be designed with mixed-face dome-style cutterheads designed to work in the compact basalt that is expected on these contracts at pressures of up to 4 bars. 
As the TBMs progress, they will install 1.400mm wide by 275mm thick pre-cast concrete lining rings, which consist of five segments plus a key.

Pune’s Metro network will comprise three rail corridors with a total length of 54.5km. Construction of the first two phases is currently underway, while the third phase was approved for construction by the government of Maharashtra in October 2018. The Pune Metro is scheduled to be completed in 2022.
