NOIDA: The stage is set for the demolition of the illegal Supertech twin towers in Noida Sector 93 is anticipated to take place within the next hour.
Gautambudh Nagar Control Centre has been placed at the Jaypee Flyover adjacent to the Twin Tower from where instructions for the relapse of the Tower will be provided.
The Noida police have barricaded most of the routes surrounding the twin tower. Around 7,000 residents from the neighbouring Emerald and ATC societies have been evacuated and additionally, ambulances and sprinklers have been provided to the communities living near the tower (as debris and a massive layer of dust is anticipated after the trigger button is pressed).
Alok Singh, Commissioner, Uttar Pradesh Police just reached the Incident Command Centre to inspect the preparations before the demolition of the Super tech twin tower.
An NDRF team has been deployed to the spot, and the neighbouring societies have been handed over to the police. At least 100 water tankers and fire extinguishers have been provided to settle all the debris that will come out as a result of the blast. Cameras have been installed on all routes and roads to ensure that no car or person is present in an area which is considered to be unsafe.
Additionally, the Noida Expressway will be closed at 1:30 pm. At around 2:30 pm, the Executive Engineer has been instructed to press the green button to blast the towers.
The Noida police have coordinated with Google to close the routes and to show that this area is closed. The Noida Expressway will be closed at 1:30 pm and will remain closed for 30 mins post the blast.
It is said that the towers -- both taller than Delhi's iconic Qutub Minar -- will be brought down in less than 15 seconds by waterfall implosion technique. They will be the tallest structures yet in India to be demolished, officials said.
There was excitement and anticipation as several people, including families and children, gathered at the site on the intervening night of Saturday and Sunday, clicking selfies and taking videos of the two towers
Over 3,700 kg of explosives will be used to bring down the structures in pursuance of a Supreme Court order that found their construction within the Emerald Court society premises in violation of norms.
Several of them left on Saturday itself, with some going to relatives' or friends' places in Delhi-NCR only while some driving out to Uttarakhand and Rajasthan on short vacations.
The closest buildings next to twin towers are Aster 2 and Aster 3 of Emerald Court society which are just nine metres away. The demolition would be done in a manner so as not to cause any structural damages to other buildings, the officials said.
The air space in one nautical mile radius above the blast will also remain briefly unavailable for flights during demolition time, according to Noida Authority. All work related to placement of explosives and connecting them is already complete.
"Once last-minute checks are done and all teams get down from the buildings, the two buildings Apex and Ceyane, have to be inter-connected. After that a 100-metre-long cable would be run from the towers to the exploder to demolish the buildings," Edifice Engineering's project manager Mayur Mehta said on Saturday. "Once we get the clearance from the police department that the exclusion zone is 100 per cent clear, then at 2.30 pm on Sunday we will press the button," he said.
Mehta said only six people, including three foreign experts, Indian blaster Chetan Dutta, a police officer and himself, will remain within the exclusion zone to push the button for the blast.
Asked how confident he was regarding safe demolition, Mehta told PTI: "100 per cent. I don't have any other word. We are 100 per cent confident." Mehta's Mumbai-based Edifice Engineering has been tasked with safely pulling down the structures.
The edifice has roped in South African experts Jet Demolitions for the project. The whole exercise is being overseen by the local Noida Authority.
His brother and Edifice Partner Utkarsh Mehta has assured residents of adjoining societies that there will be no damage to their homes except for chances of "cosmetic cracks" on outer paint and plasters of some structures.
On duration of demolition, he said first all explosives would blast in a series from the bottom floor to the top in eight to nine seconds, and then the buildings would take another four to five seconds to come down, with the whole event taking place under 15 seconds.
"The buildings are planned to come down in the south-west direction, away from the nearby buildings and towards the open area," Mehta said.
On how many options they had for demolition of the twin towers, Mehta said there are basically three techniques to safely raze down any structure of such a scale - diamond cutter, use of robots and implosion. "The technique is chosen on the basis of three parameters - cost, time and safety," he said.
He said the 'diamond cutter' would have taken over two years of time to completely demolish the twin towers safely, and its cost would have been five times of the implosion method.
On using robotics, he said this technique would have caused a lot of noise over a period of 1.5 years to two years and disturbed the residents of nearby Emerald Court and ATS Village. "Its cost would have been less than the diamond cutter technique but more than implosion," he said.
The Edifice boss said since the Supreme Court had also ordered that this project should be done in the shortest possible time and with no disturbance to neighbouring residents, the implosion technique became the choice.
Meanwhile, in an advisory issued to the public Saturday evening, the Noida Authority asked people, especially children, the elderly and patients, living in nearby areas to wear face masks in the aftermath of the demolition as a precautionary measure.
The authority especially asked residents of nearby Parsvnath Prestige, Parsvnath Srishti societies, village Gejha and others in Sectors 93, 93A, 93B, and 92 to wear face masks after 2.30 pm.
