Noida: The Supertech Twin Tower, which is higher than Delhi’s Qutub Minar, built in Noida, Uttar Pradesh, will be demolished on August 28. Project officials said the two buildings, a little over 100 meters high, would take 9 to 10 seconds to explode and collapse like a pack of cards in a total of 15 seconds. In this way, these will become the tallest buildings in India to be demolished.
Utkarsh Mehta, chairman of Edifice Engineering, who is looking after the demolition of the illegal twin towers of Supertech, told News18 in a special conversation that this process of demolition will be carried out in a scientific manner. About 3500 kg of explosives is being used to ground these two buildings, which have been put through more than 9600 holes in both buildings.
The explosion will continue for 9 to 10 seconds
Utkarsh Mehta said, ‘It will take 9 to 10 seconds for all the explosives to explode and there will be a loud sound of an explosion. After the blasts, the buildings will not collapse in one go and it will take four to five seconds for them to completely turn into a pile of rubble.
He told that during this time a plan has been made after studying a lot to avoid the dust storm and to keep the vibration to a minimum. “It will take about 10 minutes for the dust to clear up,” he said.
The explosives used in the demolition of the Tweet Tower include detonators, chemical mixtures, and shock tubes, which contain explosive material in a ‘gel’ or powdered form. “These explosives are not very effective but when used in large quantities they can break concrete,” said an official.
35 thousand cubic meters of debris will come out of the twin tower collapse
According to estimates prepared by project officials, the collapse of the Apex (32-storey) and Cyan (29-storey) buildings will create about 35,000 cubic meters of debris and dust, which will have to be disposed of.
Regarding this, Noida Authority General Manager (Planning) Ishtiaq Ahmed said that 21,000 cubic meters of debris will be removed from there and dumped on an uninhabited land of 5 to 6 hectares and the rest will be filled in the basement of the twin tower, where a pit will be made. Has gone.
Mehta told that the trucks will make about 1,200 to 1,300 trips to collect the debris. “However, the delay is a good thing. The team of Jet Demolitions has been monitoring the wind flow for the past one week and they have found the wind flow to the west. If this trend continues, then most of the dust will move towards the front of the Twin Towers, which is the part of the road in front and is open.
The company will recover its cost from the debris
However, the entire debris will not go to waste. About 4,000 tonnes of iron and steel will be generated from this, which will be used by the Edifice to cover the cost of demolition.
Noida Authority also has a construction and demolition waste management plant in Sector 80, which has a capacity to dispose of 3000 tonnes of waste every day. However, it is not yet clear whether this debris will be disposed of there and if it is done, how and in how much time.
Edphis Engineering’s first major work
Let us tell you that Mumbai-based company ‘Edphis Engineering’ along with its South African partnership company ‘Jet Demolitions’ is handling the demolition, which for it is one of the biggest civil engineering feats in the world. Edifice Engineering has previously undertaken the demolition of illegal residential buildings in Maradu in Kerala, the Secretariat and Central Jail in Telangana, and the old Motera Stadium in Gujarat.
Significantly, on the orders of the Supreme Court, these twin towers of Supertech located in Sector 93A of Noida are being demolished. The court termed these buildings illegal and said that they were constructed in violation of the rules.
