Tunnel boring machine manufacturer Terratec on Friday completed factory acceptance tests (FAT) on TBM S64B for constructing Delhi Metro’s 23.622 km Silver Line which will connect Aerocity – Tughalakabad via 16 stations.
This refurbished 6.61m diameter Earth Pressure Balance (EPB) machine will the first of three machines to be deployed by J Kumar for building twin tunnels on 65.1 km Delhi Metro Phase 4 project‘s 6.116 km Package DC-08 between Aerocity – Kishangarh.
Back in 2018-2020, this Ø6.61m dual-mode Terratec TBM, then nicknamed as Godavari-4, was deployed by J Kumar – CRTG JV to build 2 tunnels for Package UGC-05 of Mumbai Metro’s 33.5 km Line-3 (Aqua Line).
The machine, now nicknamed as Shalini, will be deployed by J Kumar likely from Aerocity Station where J Kumar’s team began diaphragm wall (D-wall) works in March.
Delhi Metro Rail Corporation (DMRC) had awarded J Kumar with 65.1 km Delhi Metro Phase 4’s Rs. 1611.74 crore contract for Package DC-08 in March 2022 with a 42 month deadline.
J Kumar’s 6.116 km Aerocity – Kishangarh section is on the western-end of the line and comprises of twin tunnels, and 4 stations at Aerocity, Mahipalpur, Vasant Kunj & Kishangarh from chainage (-) 760 mt. to 5356.285 mt.
Besides this machine J Kumar will deploy another refurbished machine (S63B from Mumbai’s Line-3) and a brand new machine whose serial number I’m currently unaware of.
