DELHI (Metro Rail News): Shanghai Tunnel Engineering Co. Ltd. (STEC) received the first of four tunnel boring machines for the 82.15 km Delhi – Meerut RRTS project’s twin tunnels on Friday morning at Anand Vihar Station.
In December 2020, STEC was awarded a disputed contract to build four tunnels between New Ashok Nagar DN Ramp – Anand Vihar – Sahibabad UP Ramp for the project’s 5.6-kilometre Package 4.
In September 2021, the team completed factory acceptance testing (FAT) for this 7.5m diameter earth pressure balance machine, called Sudarshan 4.1, at their Shanghai site.
Terratec completed FAT for 3 TBMs that Afcons Infrastructure would deploy to build Package 8’s tunnels between Brahampuri and Begumpul in Meerut in Q4 2021.
