The 10-member panel has also recommended that electronic surveillance should be provided all the way down to the ground floor keeping in mind the possibility of another commando action or an air strike by terrorists. 

   TOI was first to report the committee findings last month. 

   The panel—appointed to create security control rules for the 430 most vulnerable buildings in the city—has directed state to implement the new rules within six months to ensure that vital installations are prepared for any eventuality. 

   The report, which was presented to the urban development department on February 20, was made public on Thursday. The rules will make it mandatory for buildings to undertake a number of fortification measures. These include digital mapping of building plans, construction of concrete walls around the structure’s perimeter, automated spikes along the approach road, coating of basement columns with steel, pitched roofs to deflect explosives hurled at the buildings and having convex structures instead of concave. 

   The plan calls for removal of dense vegetation and signages as well as basement parking. After studying several buildings, the committee suggested that the Development Control Rules, 1991, be altered, and the Mumbai police carry out an immediate review of all the 430 buildings from a security point of view.
