Noida's Twins Tower To Be Demolished In Just 9 Seconds

4 tonnes of explosive required say, officials.

Noida: Supertech Twin Tower is finally at its urge to get demolished. Up to four tons of explosives could be used to raze down the illegal Supertech twin towers in Noida and the implosion of the nearly 100-metre tall structures on May 22 would take just nine seconds, according to officials.

Also, around 1,500 families living in close vicinity to the towers located in sector 93A would be moved out of their homes for around five hours when the implosion takes place at 2:30 pm on May 22, they said.

According to the demolition plan shared by Edifice Engineering, the company which has been handed the job said the stretch of the Noida-Greater Noida Expressway close to the site would also be shut for traffic for an hour, while security personnel would be deployed in the area in large numbers on the day.

Taking notes from the Supreme Court's order, the demolition of Supertech's Apex (100 metres) and Cyane (97 meters) on August 31 last year as the twin towers had come up in violation of building norms.

The Supreme Court had also rapped the local Noida Authority for approval of the project under its watch.

Sharing a presentation with media on Monday, Utkarsh Mehta, partner at Edifice, said Ceyane (31 floors) will collapse to the ground first followed by Apex (32 floors).

While explaining the technicality of the process, Mr. Mehta said, "The building will fall inwards in multiple stages, floor by floor. Ten levels will act as primary blast floors and seven as secondary blast floors. The primary blast floors will have explosives in all columns. In the secondary floors, explosives will be in 40 per cent of the columns."

The company had previously demolished the 108-metre tall Bank of Lisbon in Johannesburg, South Africa in 2019 with an implosion.

The gap between the structure and an adjoining building there was around seven meters, while in Noida the space is around nine meters, according to officials.

South Africa-based Jet Demolition is providing expertise on the blast for safe implosion and a trial blast would take place ahead of the actual implosion.

"Explosives between 2,500 kg and 4,000kg will be required. A test blast has been planned in the last week of March or the first week of April to optimize the use of explosive vis-à-vis safety measures," Mehta said.
