SNC Launches Bangalore Metro ORR Line P2’s 1st Steel Girder
Shankaranarayana Constructions (SNC)’s launching crew on early Sunday morning launched the first steel composite girder for Package 2 of Bangalore Metro’s 56 km Blue Line on the Outer Ring Road (ORR).
The city’s new Blue Line by Bangalore Metro Rail Corporation Ltd. (BMRCL) is being developed in Phase 2A (ORR Line) and Phase 2B (Airport Line) to connect Silkboard – KR Puram – Bengaluru International Airport through 30 stations.
The 40 meter long girder weighs 80 MT and was placed on top of piers ORP 459 – ORP460, located at Doddanekundi Split Flyover, for the ORR Line’s 8.377 km Package 2 (Kodibeesanahalli – KR Puram).
Just south of this spot, SNC in May had launched their 100th U-girder span between piers ORP-450 and ORP-451 – see details & images.
BMRCL awarded ORR Line Package 2’s Rs. 623.55 crore contract to SNC in May 2021 with a tight 27 month deadline.
SNC’s scope includes constructing the line’s Kodibeesanahalli – KR Puram section’s 8.377 km viaduct, 7 elevated stations at Kodibeesanahalli, Marathahalli, ISRO, Doddanekundi, DRDO sports complex, Saraswathi Nagar and K R Puram, a 1.097 km depot-line linking to the existing Baiyapanahalli Depot and a 0.30 km pocket track.
Package 2’s superstructure includes 27 steel composite spans. A twin steel composite girder will be launched in the coming days to complete launching activities for this span. This will be followed by slab casting.
This isn’t the first steel girder of the line though. Back in April 2023, Afcons Infrastructure working on 9.859 km Package 1 (Central Silkboard – Kodibeesanahalli) had launched the first one at Bellandur Flyover on top of split portal piers ORP 228-229, and followed it up with another launch on top of piers ORP 229-230 in June.

Very good achievement more ever if this line from silk board to K R Puram open to public within march 2024 more helpfull pl intimate possible date
Sir , not before mid 2025 or early 2026..there is a lot pending. Hardly 50 percent is done.
It’s just a dream. Not a single metro station in that strech is even 10% complete, laying line, metro coaches gonna take at least 2027 after considering BMRCL’s track record!
second girder also placed
Remarkable achievement. Congratulations to SNC whole team. Keep it up
Witnessed this . SNC is progressing at a good pace . Station works should be fast tracked now .
However i am wondering NCC’s progress . Looks like they are the slowest . Hope they dont end up at Simplex’s situation . The maximum contract is bagged by them and they are the slowest among all in blue line .
Here are my observations :
1. SNC might meet its deadline .
2. Afcon(Silkboard-Kodibeesanahalli ) Will be delayed by 1 year or so look at the construction pace .
3. NCC will not be able to meet even 2030 deadline .
Despite NCC has all the benefits of lesser traffic from Hebbal to Airport to fast pace their construction work . .
A big salute to Team SNC. Lifting 80 mt is nothing important as heavyweight cranes available in India. But logistics of 40 mts ie 135 ft girder – assembly, transportation, synchronising & overnight erection not a joke in indiscipline Bangalore road . Only one fear , this type of Practical Civil Engineers once became old age who will look after Indian infrastructure.
Congratulations to team once again as I involved in Delhi metro 1999 to 2004 & know pain on commitments
