Chief Minister Yogi Adityanath has directed strict compliance with safety standards during the demolition of the Supertech twin towers in Noida.
Chairing a high-level meeting at Lok Bhawan to review the preparations for the demolition, the chief minister asked the officials concerned to “ensure the safety of the people residing in the adjoining residential complex during the entire process, at all costs”.
The chief minister stressed on taking care of environmental challenges as well that will arise due to the demolition. Strict action should be taken against the culprits of this case, he added.
In line with the instructions of the chief minister, Infrastructure and Industrial Development Commissioner (IIDC) Arvind Kumar has issued detailed guidelines regarding the same.
He said preparations for the demolition of the twin towers, scheduled for August 28, had been completed. A total of 660 buildings of Emerald Court and 762 buildings of ATS Village would be vacated on August 28 morning in this context, he said.
As per the directions of the chief minister, for maintaining safety and security in the area, traffic movement on the roads around the twin towers will be restricted and the Noida-Greater Noida Expressway will be closed for half an hour at the time of demolition.
The demolition is expected to leave 80,000 tons of debris which will be disposed of in the next three months as per the fixed timeline.
The safety of the GAIL (India) gas pipeline located near the tower was being ensured and alternative parking arrangements for vehicles of Emerald Court and ATS Village Society and security of the gardens being made, Arvind Kumar said.
As per the information shared by the IIDC, the demolition of Supertech’s 32-storey twin towers will be executed by Mumbai based Edifice Engineering. The agency has in the past successfully carried out the demolition of one such skyscraper in Cochin.
The waterfall implosion technique will be used for the demolition. It is considered very useful for demolishing a building in the desired direction as per the design. On April 10, testing was also conducted based on the results of which the Central Building Research Institute (CBRI) has prepared a revised blast design.
Over 3,700 kg of explosives will be used to raze the twin towers. Explosives will be filled in around 9,600 holes drilled in the columns and shears of the skeletal structures of the twin towers for the demolition.
On August 28, at exactly 2:30 pm, the 30-storey tower number 16 and 31-storey tower number 17 will collapse like a house of cards in a process that would take less than 12 seconds for them to come down.
The demolition agency has prepared a C&D waste management plan to dispose of the rubble generated after the demolition. The estimated 80,000 tons of total debris will be segregated on-site and steel and concrete will be separated from this debris.
Around 50,000 tons of debris is set to be accommodated in the two basements of twin towers, while the remaining 30,000 tons will be scientifically processed and converted into tiles, etc., at the C&D plant in Noida. According to the plan, this entire process of disposal of debris will be completed in the next three months.
The chief minister has given directions to tackle the environmental challenges as well. In view of the same, to check the air quality after demolition, equipment will be installed at six locations by the Uttar Pradesh Pollution Control Board.
A 12-metre-high geo fiber cloth will be used to protect the Emerald Tower and ATS Village from the dust generated during the segregation of debris accumulated as a result of the demolition. Water tankers, sprinklers, and smog guns will also be used to clear the dust. Besides, sweeping machines will be installed on the road coming within a radius of about two kilometres.
