The Adani Group has emerged as the lowest bidder for both segments of Bengaluru’s 16.75-km tunnel road project, which aims to link the Hebbal and Silk Board junctions. This initiative, which operates under a build-operate-transfer model, will be financed 40 percent by the government, while the remaining funds will be sourced from private investors.
Nevertheless, the Adani Group’s bid of Rs 22,267 crore surpasses the government’s estimated cost by approximately 24 percent for the first package and 28 percent for the second.
This situation has raised concerns, as the bids are considerably above the initial government estimate of Rs 17,698 crore. Other competitors, including Vishwa Samudra Engineering Ltd, have also presented bids that exceed the government’s estimates.
