Mumbai: A day after a foot overbridge connected to CSMT railway station collapsed, killing six persons and injuring 31, the Brihanmumbai Municipal Corporation has decided to dismantle the structure. In a meeting chaired by BMC commissioner Ajoy Mehta Friday morning, it was also decided that the civic body’s Chief Engineer (Vigilance) would conduct an inquiry into the causes that led to the deck of the FOB collapsing on Thursday evening. Ward Officer Kiran Dighawkar said work on dismantling the FOB had begun and cranes and gas-cutters had been assembled for the work.

Another official said the Chief Engineer (Vigilance) has been asked to submit his preliminary report within 24 hours identifying staff responsible and the role of those who carried out its structural audit.

The FOB that collapsed on Thursday was marked C2B. This means it needed minor repairs only. Tenders were floated for the repair but it got held up,” the official had said Friday morning. After a visit to the site Friday morning, Chief Minister Devendra Fadnavis had asked Mehta to fix “primary responsibility” for Thursday’s foot overbridge collapse by evening.
