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 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.
