Chief Minister of Gujarat Vijay Rupani has approved construction of buildings of 70 floors or more in five major cities of the state. As per present rules, maximum permissible limit for tall structures in the state was 23 floors. Now the state government has decided to amend the common general development control regulations (GDCR) to allow construction of high-rise structures of 70 or more floors in Ahmedabad, Vadodara, Surat, Rajkot and Gandhinagar. The new rules regarding tall buildings approved by the government will be applicable to structures which are over 100 mtr in height. A special technical committee will be set up to give approval to such projects. The plot size to construct a skyscraper having a height between 100 to 150 mtr must be 2,500 sq. mtr and 3,500 sq. mtr if the proposed height is above 150 mtr. Apart from preparation of a disaster management plan, a wind tunnel test of the model structure has been made compulsory under the new rules.
