New Delhi: The demolition of realty major Supertech Ltd's twin 40-storey towers of its Emerald Court project in Noida will be carried out in just nine seconds using up to four tonnes of explosives. The 100-metre tall structures will be razed down on May 22, PTI reported quoting officials.

For safety of the residents living in the vicinity of the towers located in Sector 93A, around 1,500 families will be moved out of their homes for around five hours when the implosion takes place at 2:30 pm on May 22.

People residing in Emerald Court, nearby ATS Greens Village and parts of Parsavnath Prestige, a park and the road in the front of the towers will be moved out temporarily.

Officials said a stretch of the Noida-Greater Noida Expressway close to the site would be shut for traffic for an hour. The demolition will be carried out by Edifice Engineering.

On August 31 last year, the Supreme Court had ordered the demolition of Supertech Ltd's towers under construction within three months for violation of building norms in "collusion with NOIDA officials". 

The court held that illegal construction should be dealt with strictly to ensure compliance with the rule of law.

The court had directed that the entire amount of home buyers be refunded with 12 per cent interest from the time of the booking. It also said that the the RWA of Emerald Court project be paid Rs 2 crore for the harassment caused due to the construction of the twin towers, which would have blocked sunlight and fresh air to the existing residents of the housing project.

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).

"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," PTI quoted Mehta as saying. 

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

South Africa-based Jet Demolition has been roped in for providing expertise for safe implosion and a trial blast will take place ahead of the actual implosion, PTI reported.

"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 optimise the use of explosive vis-à-vis safety measures," Mehta said.

The ground work for the implosion has been underway for the past several weeks.

This includes removal of structures like electrical fittings, plumbing items, doors and windows. Walls are also being demolished to reduce the amount of rubble the implosion would create.

Mehta said the company was also preparing two to three layers of wired mesh around columns that would be filled with explosives and laying 'geo-textile fabric' on the ground to stop debris from flying off in an uncontrolled manner.

The implosion, he said, would induce a pull away from the premises of Emerald Court. Around 600 families live in the Emerald Court housing society and on which the twin towers are located.

According to Noida Authority officials, experts will examine Emerald Court and the buildings in the vicinity for damage assessment after the implosions.

In case of any damage, locals have been assured of an insurance cover.

The specially-prepared cushions on the ground will reduce the impact of rubble falling on it and minimise vibrations.

Traffic on the expressway will be stopped for an hour. Security personnel, including police, will be deployed in the area.

"We will need people to evacuate the entire area during the implosion. We have given a report in this regard to the Noida Authority, but a final evacuation zone will be decided in consultation with the police," Mehta said.

"At the time of the blast, only five persons – two foreign experts, one police personnel, one blaster, and the Edifice project manager, will be present in the exclusion zone to execute the demolition," he further said.
