SNC Launches Bangalore Metro ORR Line P2’s 100th U-Girder Span
Shankaranarayana Constructions (SNC)’s launching crew on Friday night celebrated the erection of their 100th U-girder span for 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-450 and ORP-451, located at Doddanekundi Split Flyover, for the ORR Line’s 8.377 km Package 2 (Kodibeesanahalli – KR Puram).
This 100th span marks the launching of 200 out of 544 U-girders for Package 2. SNC had cast their first U-girder at Kacharakanahalli near Whitefield in February 2022 from where 544 girders, ranging from 18m to 28m, are currently being cast in two casting bays. The first U-girder was launched in June 2022 in Mahadevapura.
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.
In Package 2, SNC will launch 446 U-girders for its viaduct and 98 U-girders at the track-level within the 7 stations en-route.
