At 2.15 p.m., a short-duration siren was heard, followed by two to three sirens at 2.30 p.m., only minutes before the test blow.

The Noida authorities has hired Edifice Engineering and Jet Demolitions to destroy the Supertech twin buildings.

In the Apex tower, a test blast was carried out using five kg of explosives. The purpose of this exercise was to determine the quantity of explosive that would be required for the real destruction of both towers on May 22.

On August 31, last year, the Supreme Court ordered the destruction of Supertech’s Apex (100 metre) and Ceyane (97 metre) towers, citing violations of construction codes.

The top court also slapped the Noida Authority for approving the project when it was under its supervision.

According to previous estimates, up to four tonnes of explosives might be used to demolish the Supertech twin towers, and the implosion of the approximately 100-meter tall structures on May 22 would take barely nine seconds.

Additionally, around 1,500 residents living in close proximity to the buildings in Sector 93A will be displaced from their homes for approximately five hours when the implosion occurs at 2.30 p.m. on May 22.

According to the demolition plan supplied by Edifice Engineering, a part of the Noida-Greater Noida Expressway near the site would be closed to traffic for an hour, and security forces would be stationed in significant numbers in the vicinity on the day.

Utkarsh Mehta, partner at Edifice, claimed Ceyane (31 stories) will fall first, followed by Apex, in a presentation to the media on Monday (32 floors).

“The structure will collapse inwards in stages, floor by floor.” The primary blast floors will be ten, while the secondary blast floors will be seven. All columns in the principal blast levels will be filled with explosives. Explosives would be in 40% of the columns on the secondary levels, according to Mehta, who also explained the technical components of the operation.

In 2019, the business used an implosion to demolish the 108-meter-tall Bank of Lisbon in Johannesburg, South Africa.

According to authorities, the distance between the construction and a neighbouring building there was roughly seven metres, but in Noida it is around nine metres.

Jet Demolition, located in South Africa, is offering knowledge on the blast for a safe implosion, and a trial blast will be conducted prior to the actual implosion.

“Explosives weighing between 2,500 and 4,000 kg will be needed. To optimise the usage of explosives in relation to safety precautions, a test detonation is scheduled for the latter week of March or the first week of April “Mehta said.

Residents in the exclusion zone (blast radius) will be required to leave at least three hours before the implosion and will be allowed to return at least two hours later.

Emerald Court, ATS Greens Village, sections of Parsavnath Prestige, a park and the road in front of the towers, as well as a stretch of the Noida Expressway, are all included in the exclusion zone.
