FSI of 5.33 okayed for Mantralaya revamp: Architect

Mumbai: A floor space index (FSI) of 5.33 was sanctioned for the Mantralaya redevelopment project right at the start, said architect Raja Aderi. 

    Aderi said the FSI was approved by the urban development department. "Besides, a part of the seventh floor was occupied earlier too, and we have not built more than what was existing earlier. The terrace is still there," said a public works department official. 
    Fire department officials said the building was occupied prior to the June 2012 fire, and had been refurbished, hence, the claim that offices were moving in without being issued occupation certificate is not correct.
