NEW DELHI (Metro Rail News): Afcons Infrastructure starts pouring concrete to cast the first batch of tunnel ring segments for Delhi Metro’s 23.622 km Silver Line, connecting Aerocity and Tughalakabad via 16 stations.
The company is in charge of constructing the 6.981 km Package DC07 of the 65.1 km Delhi Metro Phase 4 project, which would link the eastern end of Sangam Vihar Station and Sarita Vihar Depot. The Delhi Metro Rail Corporation (DMRC) granted them a contract worth Rs. 1669.20 crores with a 42-month deadline in January 2022.
Cooper Turner Beck group and Afcons have partnered to supply accessories to their casting yard.
Afcons scope includes the construction of three underground stations at Maa Anandmayee Marg, Tughlakabad Railway Colony, and Tughlakabad, where they will interchange with the station for the Violet Line constructed in Phase 2.
Afcons will construct a total of 8 tunnels, and the DMRC needs to deploy at least five tunnel-boring machines (TBMs). However, according to the source, only four machines, a combination of refurbished Robbins and Herrenknecht machines, will be used.
