Professor Chandra Kishen of the Bengaluru IISc, tasked with investigating the January 10 collapse of an under-construction metro pillar near Nagavara, has found that the inadequate supporting structures for its reinforcement cage led to the accident that claimed two lives.
Kishen submitted a 27-page report by email to the Bengaluru Metro Rail Corporation Limited on Saturday, after collecting, reviewing and analysing data related to the pillar’s 18m reinforcement cage. The report also details measures to be taken to prevent such accidents.
Speaking to The Indian Express, Kishen explained that the 18m structure was not a single-piece structure but a combination of reinforcement rods measuring 12 m each.
