Excavation Begins for Delhi Metro Airport Line’s Extn to Dwarka ECC

Towards the end of January, workers from YFC – MBZ JV began soil excavation work for constructing a 1.878 km underground extension of the Delhi Metro’s 22.9 km Airport Express Line from Dwarka’s Sector 21 Station to the upcoming Exhibition-cum-Convention Centre (ECC) in Dwarka’s Sector 25.

YFC-MBZ JV emerged as the lowest bidder for constructing this CC-127 section of the 162 km Phase 3 project in November 2017 after placing a bid of Rs. 302 crores, well below the Delhi Metro Rail Corporation’s estimate of Rs 310 crores. Besides twin box tunnels, YFC – MBZ will build one underground station called ‘ECC Centre’.

Note – no tunnel boring machines will be deployed here. The line’s alignment hasn’t been revealed by the DMRC but will most likely look like this with a provision to be extended to Gurgaon in the future:
