A few hours ago, J Kumar Infraprojects and Sunder Cranes erected the first two 25m U-girders for constructing Mumbai Metro’s 11.38 km Line-9 (northern leg of Red Line) which will connect Dahisar East with Mira Bhayandar through 8 stations.
This major milestone was recorded at piers P63 – P64 located right across from Thakur Mall near Pandurang Wadi Station’s site. Back on New Year’s Eve, the 9 meter tall P63 was the line’s first pier to receive a 60 MT pier cap.
The contract for Line-9’s construction under package CA-48 – a northern extension of the under construction 16.5 km Line-7 – was awarded to J Kumar Infraprojects by the MMRDA in January 2020 after they had emerged as the lowest bidder for this line and Line-7A (southern extension of Line-7) in September 2019.
Their scope includes the construction of 3 double-decker viaducts on Kashmira Road measuring 1.5 km, 1.1 km and 754m for vehicles and metro trains, and 8 stations at Dahisar East (new station box), Pandurang Wadi (interchange with Line-10), Miragaon, Kashigaon, Sai Baba Nagar, Meditya Nagar, Shaheed Bhaghat Singh Garden and Subhash Chandra Bose Ground.
Here are some snaps. J Kumar’s team will eventually launch a total of approximately 700 U-girders for this line:
Due to Mumbai’s challenging site conditions typically the first girder has been launched 12-18 months after contracts are issued, and this fits right in at the 14th month. Such launches will now become a nightly affair.
