Preparations are underway to demolish the Twin Towers of Supertech Emerald Court Society located in Noida Sector 93 A. It will take just nine seconds to ground it. For this 2500 kg of explosives will be used. They are being demolished on the orders of the Supreme Court. This work will be completed by 22 May. Noida Authority and Roorkee-based Central Building Research Institute have chosen Edphis Engineering for this, it will be supported by South African company Jet Demolition.
Utkarsh Mehta, partner at Edphis Engineering, said the blast would take about 9 seconds. A few milliseconds later the larger tower will be dropped after the smaller tower. These pillars will be covered with wire and geotextile fabrics to collect concrete debris when the building is demolished.
According to Mehta, about 2,500 kg to 4,000 kg of explosives may be required to bring down the Twin Towers. The trial blast will happen later this month or early next month. The explosives would be kept at a facility about 100 km away and brought in as needed. It can take 12-15 days to load explosives into the building. The height of one of these towers is 103 meters, while the height of the other is about 97 meters. Both the towers are built in about 7.5 lakh square feet.
According to Mehta, four adjoining buildings, two of Emerald Court and two towers of ATS Village, will be covered with geotextile fabric to avoid damage caused by debris. The explosion will blow dust and it may take about 4 to 10 minutes for it to go off. During this the surrounding area will be evacuated. The area may remain closed for about five hours a day.
Mehta also informed that only five people including a blaster, a police officer and the project manager will be present here. The Noida-Greater Noida Expressway will remain closed for about half an hour a day to avoid any accidents. There will be no damage to the surrounding buildings during the demolition, but still it is being insured. The blast has been designed in such a way that there is no damage to the Emerald Court building.
Noida Authority CEO Ritu Maheshwari said that the regional office of the Pollution Control Board is assessing how much pollution will be caused by demolition of the towers. The land belongs to the builder and as per the norms, he will decide what to do with it after the demolition. The cost of this is being borne by Supertech. The Supreme Court had on August 30 last year ordered the demolition of the Twin Towers within three months for violating norms on the distance between buildings.
