Noida Supertech twin tower demolition: How explosives will bring down skyscrapers
Everything is set for the safe demolition of the Supertech twin towers here on Sunday, which is expected to be a spectacular engineering spectacle that will demolish structures nearly 100 meters high due to corruption.
last-minute checks remain as the towers – taller than the famous Qutub Minar in Delhi – will be destroyed in less than 15 seconds using the waterfall blast technique. Supertech Twin Towers before being destroyed with explosives by Supreme Court ruling in Noida, Saturday 27 August 2022
According to officials, these will be the tallest structures in India that have yet to be demolished. Noida Authority CEO Ritu Maheshwari told : “All measures have been taken and agreements have been made for the safe demolition of the Twin Towers as scheduled at 2:30pm tomorrow.
More than 3,700 kilograms of explosives will be used to collapse the structure, in line with the Supreme Court’s ruling that their construction at the Emerald Shipyard was illegal.
Approximately 5,000 residents of Emerald Court and neighboring ATS Village communities in Area 93A had to leave their property by 7:00 a.m. Sunday, as well as evacuate nearly 3,000 vehicles and bring 150-200 pets with them. , including cats and dogs, during the day.
The nearest buildings next to the twin towers are Emerald Court Society’s Aster 2 and Aster 3, just 9 meters away. Officials said the demolition would be done in a way that would not cause any structural damage to other buildings.
While the nearby Noida-Greater Noida highway will be closed from 2:15pm to 2:45pm, the city will remain a drone-free zone.
According to the Noida government, the airspace within one nautical mile of the site of the explosion will also be inaccessible to flights during the demolition process for a short time.
All work on placing explosives and combining them has now been completed. By design, all that was left to do was connect the twin towers and lay a 100-meter cable from the structure to the explosive device, from which the button would be pressed on Sunday.
“After a last-minute check and all teams have left the buildings, the Apex and Ceyane buildings should be merged. A 100-meter demolition cable will then be routed from the towers to the explosive device,” said Mayur Mehta, Edifice Engineering project manager.
“Once we get permission from the police that the restricted area is 100% cleared, we’ll push the button at 2:30 p.m. Sunday,” he said. Mehta says that only six people, including three foreign experts, Indian Chetan Datta, a policeman and him, will stay in the exclusion zone to press the detonation button.
When asked about her confidence level to safely demolish, Mehta told PTI, “100%. I have no other words. We are 100% sure. “
Mehta’s Edifice Engineering, based in Mumbai, was tasked with the safe demolition of the structure. Edifice brought in South African experts from Jet Demolitions on this project. All exercises are controlled by the local Noida government. Mehta assures residents of neighboring cities that no damage will be done to their homes, except for the possibility of “aesthetic cracks” in the exterior paint and plaster of some construction.
As for how many options they have available to destroy the Twin Towers, Mehta said there are basically three methods to safely destroy any structure of that size: diamond cutting, robotics, and blasting. . The technique was selected based on three parameters – cost, time and safety, he said.
He said that “diamond cutting” would take more than two years to completely destroy the Twin Towers, and five times more expensive than the explosive method. Regarding the use of the robot, he said the technique would generate a lot of noise over a period of 1.5 to two years and disturb the residents of nearby Emerald Manor and ATS Village.
“Its cost will be less than diamond cutting, but greater than blasting,” he said. The head of the building said that since the Supreme Court had also ruled that the project should be completed as soon as possible and without disturbing local residents, the blasting method had become the project’s choice. .
Ganesh Saha said roads leading to the Twin Towers in Noida Sector 93A will have a detour from Sunday morning, while the Noida-Greater Noida Highway, just 200 meters from the demolition site, will be open to pedestrians from two hours until 3 pm. Saha said updated channels on real-time detours and traffic situations will appear on Google Maps on Sunday, adding that emergency vehicles have been arranged.
DCP (Noida Central) Rajesh S. said around 400 police officers will be deployed to enforce law and order, while PAC and NDRF personnel will also be on site during emergency situations. Chief physician Dr Sunil Sharma said the health ministry will deploy six ambulances with officials and medicine at the scene.
Beds are reserved at both the district hospital and private health facilities Yatharth, Felix and Jaypee. The destruction of the twin towers will be done using the waterfall explosion technique, which will literally destroy them like a house of cards in a matter of seconds.
This stunning event will leave behind around 55,000 tons of trash, although some estimates are as high as 80,000 tons. It will take about three months to clean up and dispose of the trash.
Maheshwari said every measure is being taken to clear the dusty area after demolition. According to her, in addition to medical staff, mechanical sweepers, smoke guns and sprinklers will be installed on the construction site.
Residents of Emerald Court and ATS Village interviewed by PTI said they were concerned about the demolition, though they expressed relief that the illegal structures would finally disappear after more than ten years of dispute juridical. PTI
