Piling Work Begins for Mumbai Metro’s Hutatma Chowk Station

Workers from L&T-STEC JV earlier this month started secant piling work to build a guide-wall for Mumbai Metro Line-3’s Hutatma Chowk Station in south Mumbai. The station is being built as a part of the 4.25 km package UGC-01 which was awarded in July 2016 for a value of Rs. 2,988.53 crores.

Out of 4 stations on this package (others are Cuffe Parade, Vidhan Bhavan and Churchgate), this will be the northernmost station and also the location from where L&T-STEC’s 2 Robbins Crossover TBMs will commence their final journey towards the Chhatrapati Shivaji Terminus (CST) Station’s TBM receiving shaft using tunnel segment rings produced in Wadala.

As per the interim consultancy report produced by a JV led by Japan’s PADECO, the station is planned to be constructed using both the new Austrian tunneling method (NATM) and Cut & Cover (C&C) techniques, and is proposed to be only 17.75m wide x 252m long due to the narrow width of the site. Excerpt:

The station is located on Dr. Dadabhai Naoroji road having heritage structures on both sides. Also the carriage width available is only 20m, which is not adequate to accommodate a standard Cut & Cover station. Therefore the width of Cut & Cover box has been reduced to fit-in the available road width. Due to this only one track is housed within the C&C box. The other track tunnel, with integrated platform, is thus required to be taken below the properties and constructed by NATM.

    Every where in India metro works are in full swing but bastad cmrl is working like a tortoise in phase1 extn assholes when they complete the pilling work for phase1extn as the project was sanctioned in April 2014

      Hi, CMRL has in fact done a stellar job with PH-1’s extension! They invited bids for the underground section just days after the Central Govt approved it in December 2015. Afcons was awarded the contract in June, and 2 TBMs started tunneling in March & April towards Sir Theagaraya College. So as far as timing goes, I’m quite happy with how things panned out. The 1st of 4 breakthroughs is supposed to take place around Aug-Sept. Stay tuned 🙂

        What about phase 2 of Chennai Metro by this time the constructions should begin, it is at snail pace.

    for mumbai, devendra phadnavis seems to be confident that the construction will be within the deadline and all timing deadlines will be met. They say, this construction is different from others since they already have all the required permissions. Dont know if I should believe him
