Mumbai Metro Rail Corporation (MMRC) has achieved its 33rd breakthrough, with the completion of a 653m long tunnel from Churchgate to Hutatma Chowk station.
It is the first TBM breakthrough inside a NATM tunnel bored using a Robbins-made Dual mode hard rock TBM. Surya-2 has completed this downline stretch in 275 days using 502 rings.
“The presence of iconic Flora Fountain and various heritage buildings made out task a bit challenging. However, this unique station, in the vicinity of Hutatma Chowk, is being built by using a combination of Cut-and-Cover and NATM. This station will provide accessibility to the business centres of South Mumbai”, said Mr. Ranjit Singh Deol, Managing Director, MMRC.
The overall progress of Hutatma Chowk station is 53%. Package-1, which consists of Cuffe Parade, Vidhan Bhavan, Churchgate and Hutatma Chowk stations, stands at 80% tunnel completion and 68% station work progress.
The total tunnelling on the entire Mumbai Metro project completed is 88% and civil work is 60%.
