ITD Begins Work on Chennai Metro Phase 2’s Casting Yard

ITD Cementation India has in the past fortnight started ground work to setup a casting yard for Chennai Metro Line-4’s 10 km underground section connecting Power House Ramp – Light House Station.

The yard will be used to cast approximately 9000 tunnel ring segments for constructing the 118.9 km Chennai Metro Phase 2 project’s 5.15 km Package UG-01 (Bharathidasan Road Station to Light House) and 4.877 km Package UG-02 (Kodambakkam Flyover Station to Bharathidasan Road Station).

Chennai Metro Rail Ltd (CMRL) had awarded ITD with both package’s civil contracts in January 2022 for a combined contract value of Rs. 3743.24 crore and 48 month deadline.

The firm has since mobilized men and machinery and started geotechnical soil investigation work (see pics) to revalidate previous findings to help properly design and construct the line’s twin tunnels and stations.

ITD Cem plans to deploy four tunnel boring machines (TBMs). I hear 3 of those will be refurbished from Mumbai Metro Line-3’s Package UGC-04 (Herrenknecht S1073, S1074 and S1075). In addition, a new TBM will be procured from Herrenknecht with all 4 slated to undergo factory acceptance tests in the coming months at Herrenknecht’s plant in Tamil Nadu.
