SNC Launches Bangalore Metro ORR Line’s 1st U-Girder

Shankaranarayana Constructions (SNC) on Saturday night erected their first U-girder in Mahadevapura for constructing Bangalore Metro’s 56 km Blue Line on the Outer Ring Road (ORR).

The city’s new Blue Line by 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 27.90m long girder weighs 164 MT and was placed on top of piers ORP-473 and ORP-474, located opposite Bagmane Tech Park, for the line’s 8.377 km Package 2 (Kodibeesanahalli – KR Puram).

SNC had cast their first girder at Kacharakanahalli near Whitefield in February from where approximately 600 girders, ranging from 18m to 28m, will be cast from two casting bays.

The 13.7m tall piers on the ORR’s median were cast in January & February, and had 65T pier caps erected on top last month.

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.

According to Shankaranarayana Constructions (SNC), 40 U-girders for ORR Metro ready at its casting yard so far. Of the 321 piers between Kodibeesanahalli and KR Puram on ORR, 33 completed so far.

Such launches will now become a regular nightly affair in the city. On Monday, SNC erected the 2nd U-girder:

    Hey TMRG

    Thanks for the update on piers. More than 10% piers are done. Do you have a similar update on Afcons as well? How are they progressing with the construction?

    Hey TMRG

    Will you be covering the Bengaluru Suburban Railway? It has evolved into something that is Metro-like or RRTS-like (albeit with lesser frequency).
