The Supertech twin towers in Noida are set to be demolished at 2:30 pm today. The two massive towers – nearly 100 metres tall – will be razed down using 3,700 kg of explosives. The collapse will last for nine seconds, the project’s engineer has said, and another 12 minutes for the dust to settle. The Supreme Court had last year ordered the demolition of the towers for the violation of building norms.

Ahead of the explosion that will bring down the massive twin towers in Noida today, the project head of the engineering firm tasked with the job said he’s getting “goosebumps” since morning. “I have been getting goosebumps since morning. I am a little nervous but confident as well,” said Utkarsh Mehta of Edifice Engineering while speaking to NDTV. He said all preparations have been done and the blast will be executed at 2:30 pm.

After the explosives are set off to bring down the Noida Supertech twin towers, vibrations will be felt up to 30 metres, but only for a few seconds, that too at just about 30 mm/second. In simpler words, that’s equal to an earthquake of 0.4 on the Richter Scale. Noida routinely gets minor tremors, and structures built as per norms here can withstand a Richter Scale-6 earthquake.
Noida Twin Towers Demolition Trivia – Collapse To Be Over In 9 Seconds
The collapse of the Noida Supertech twin towers will last for nine seconds, the project’s engineer has said. He will stand next to the blaster, to be designated by the Noida administration, besides three experts from Africa and some other government officers – not more than 10 people in all – who will stand at least 100 metres away. It will take another 12 minutes for the dust to settle. It could vary a bit if wind speed isn’t the usual. After that, labourers will move in to check on adjacent buildings, and get to work on the debris immediately. The debris, of course, will take much longer to clear – up to three months for the 55,000 tonnes (or 3,000 trucks). It’ll be dumped at some designated areas in the region.
Trivia – 3,700 Kg Explosives Fitted For Noida Supertech Twin Towers Demolition
Explosives weighing around 3,700 kg have been inserted into nearly 7,000 holes in the pillars of the two Supertech towers in Noida. These holes are two metres each, meaning 14 km of holes house the explosives. To bring it all together, 20,000 circuits have been set. When triggered, these will crash the pillars in such a manner that the towers fall straight down – it’s called the ‘waterfall technique’.
The evacuation of two housing societies near the soon-to-be-demolished twin towers of Supretech was nearing completion, officials said this morning. The evacuation of around 5,000 residents of Emerald Court and ATS Village societies was scheduled to be completed by 7 am. Most of the residents have already moved out, many of them last evening itself, police officials said around 7.15 am. “The evacuation is nearing completion,” an official said. While the residents, their vehicles and pets had to be moved out by 7 am, private security and other staff will also be removed from the two societies by 1 pm, the officials added. The demolition of the two illegally built towers is scheduled for 2.30 pm. (PTI)
8 metres: That’s how close some of the adjacent apartment buildings are to the Noida Supertech twin towers that are set to be demolished today. There are several others within 9-12 metres. They have been covered in a special cloth to minimise dust penetration. In the South Africa case, other buildings were just 7.8 metres away, but the demolition was done safely.
Of the two Supertech towers in Noida set to be demolished today, Apex tower’s height is 103 metres while Ceyane stands at 97 metres. The tallest building to have been brought down with an implosion in India stood at 68 metres, in Kerala. It was demolished in 2020. The world record, too, came about that same year, when a building of 168 metres was brought down in Abu Dhabi.
Trivia – Noida Supertech Twin Towers Demolition
As many as 40 floors were planned in each of the Supertech towers in Noida originally. While some couldn’t be built due to a court halting it, some of the construction were broken down manually ahead of the final implosion-and-collapse. Now, Apex tower has 32. Ceyane has 29. The plan was to have more than 900 flats, two-thirds of which had been booked or sold. The Supreme Court ordered a refund with interest. A skeletal structure remains.
