On the night of December 10, NCC Ltd. successfully launched the first ever pre-cast segment just south of the proposed Krishna Leela Park station’s site for building the Bangalore Metro Green Line’s 6.29 km southern extension to Anjanapura Township. This milestone was accomplished roughly 10 months after they won the contract to build package Reach 4B of the Bangalore Metro’s 72 km Phase 2 project between Yelachenahalli and Anjanapura Township.
This section includes 5 new stations at Anjanpura Cross Road, Krishna Leela Park, Vajrahalli, Thalgattapura and Anjanapura Township and is expected to become operational in late 2019.
Each segment weighs 40 tons and usually 10 segments are required to build one span between two adjacent piers. For this section, NCC will launch 2020 segments which they’re currently casting at their yard in the nearby Thataguni Village. As per BMRCL’s December 2016 newsletter, 183 of them had been cast by the end of November 2016 – see recent images.
Here’s my go-to video to demonstrate how the Launching Gantry works its magic with precast segments to build modern segmental viaducts and bridges:
Going forward, I’ll be posting one-off construction images on Twitter so do follow or check out my handle.
