1st U-girder Launched for Mumbai Metro’s Line-2 in Borivali
In the early hours of July 7, workers from the J Kumar – CRTG JV launched their first U-girder at Yogi Nagar in Borivali West for building package AC-01 of Mumbai Metro’s 18.6 km Line-2 from DN Nagar to Dahisar East. Unlike the launch event held for Line-7 in May, the event here between piers #191 & #192 was rather low-key with workers placing two 24.90m U-girders weighing 150 MT one after the other.
The J Kumar-CRTG JV is responsible for constructing both packages AC-01 and AC-02 of the line and completed casting their first pier in January 2017 and erecting the 1st pier cap in May. They completed casting the first batch of U-girders for both this line and the 16.5 km Line-7 at their Bandra yard in January 2017, and as per the MMRDA’s website, a total of 84 U-girders had been cast by May 30 2017.
Besides the elevated viaduct, Package AC-01 also includes the construction of 8 stations at Anand Nagar, Rushi Sankul, I C Colony, Eksar, Don Bosco, Shimpoli, Mahavir Nagar and Kamraj Nagar –

Isn’t this part of Line 7?
Nope. This is Line-2 on New Link Road in Borivali West.
Line-7 (shown in red color in the map above) is on the WEH and passes through Borivali East.
Thank you. You are a great resource. 🙂
Nice. They are continuing work in monsoons. Must be at a slower rate.
Hi… TMRG
what is the present status of Ahmedabad Metro
Hi, rolling stock’s legal issues with CRRC just got sorted out, so the winner’s announcement will hopefully be made soon. After the contract is awarded, give at least 15 months for the 1st train to arrive.
On the civil side of things, the 6 km Vastral Gam – Apparel Park section on the EW line will first open up sometime in 2019-2020. L&T is currently carrying out demolition work to build its TBM shaft at Kalupur Station for the underground section. For updates on the other sections, see the Ahmedabad construction updates page and Twitter handle for random construction images.
Hi TMRG, I guess in bangalore metro & other metro,s use other type civil construction, here i find from one pillar to other pillar they are using single piece but in bangalore metro they use more than 5 pieces from one pillar to other pillar.
Segments used in Bangalore and elsewhere provide a smoother finishing around curves and are a lot easier to ferry on-site and erect throughout the day.
Mumbai is an exception, but I’ve found U-girders to be almost always used for metro lines on National Highways (Lucknow Line-1, Kochi Line-1, Delhi – Red/Violet/Airport Exp). They require a lot more site space and as such mostly erected in non-peak hours, but provide a unified look pier to pier.
In Bangalore, the Electronics City line (RV Road – Bommasandra) is a prime candidate where such girders could be used, but I believe they’ll be utilizing segments instead.
Thank you for your reply & How about the cost…? which costs less…?
I think U-girders consumes less time for the installation compare to segments pier to pier.
I see the line 2A needs T girders. What exactly is the difference between T girders and a U girder?
U-girders are for viaduct. If I’m not mistaken, T-girders will be used on either ends of the stations’ platform level. Some images of Mumbai’s T-girders can be seen here
Thank you. Do you still think we are on track for a 2019 opening to the public? Given the current progress being made and without anticipating any further delays? Or do you think we are lagging behind on the schedule
I believe the deadline is too tight. That combined with site constraints, traffic, rains etc aren’t helpful. Another thing to consider is rolling stock. Bids to procure them haven’t been invited yet as they’re still finalizing a loan deal. Bidding can take 6-12 months and the 1st train will arrive only after 12-15 months. Do the math and you can see how a 2019 opening is not possible. At the most, they’ll conduct a small trial run for election purposes in 2019, but that’s about it.
