Apart from taking punitive action against those responsible for the collapse of the FOB, civic chief Ajoy Mehta has issues instructions for re-auditing of all the bridges that were audited by Professor D D Desai's Associated Engineering Consultants by a different structural auditing company. Senior civic officials said that based on the findings of the second auditing report, the BMC will decide on recovering payments that have been made to the Engineering Consultants firm so far.

While documents are yet to be found, officials from the bridges department said that the FOB dates back to 1988. When the BMC had given the contract to carry out a structural audit of 296 bridges, road overbridges and foot over bridges in the city to three contractors in 2016, the auditing firm had bagged the contract for 39 for a fee of Rs 65.18 lakh.
