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 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.
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.
