Steel Infra Solution in Bhilai, Chhattisgarh on Monday completed trial assembly on a 35.5 meter long steel composite girder fabricated for 56 km Bangalore Metro Blue Line‘s viaduct on the Outer Ring Road (ORR).
Weighing approximately 2000 MT, this steel composite girder will be launched by Afcons Infrastructure between piers ORP-60 and ORP-61 alongside HSR Flyover for 18.2 km Bangalore Metro Phase 2A project’s 9.859 km Package 1 connecting Central Silkboard – Kodibeesanahalli.
Afcons Infrastructure was awarded ORR Line Package 1’s Rs. 785.23 crore contract in May 2021 after emerging as its lowest bidder in October 2020.
Their scope includes constructing the 9.859 km Central Silkboard – Kodibeesanahalli section’s viaduct, 6 elevated stations at Central Silk Board, HSR layout, Agara, Ibbalur, Bellandur, Kadubeesanahalli, and a roughly 2.84 km long flyover with loops at Central Silkboard.
Package 1’s viaduct includes 22 composite spans, while 8.377 km Package 2’s viaduct, under construction by Shankaranarayana Constructions (SNC), includes 25 between Kodibeesanahalli and KR Puram
The composite girder will now be dismantled, transported roughly 1350 km south to the site and reassembled for launch.
While we’re on the topic of Package 1’s viaduct, Afcons Infrastructure just posted this cool graphic on LinkedIn with some fun facts. They’ve so far launched around 60 U-girders out of 650.
