Noida's Twin Towers collapsed in a few seconds, dustcloud spread several meters
NOIDA : Illegally constructed multi-storey residential society Supertech twin towers in Sector 93A of Noida were demolished with explosives today. At present, there is no report of any damage to life or property due to the massive explosion of the explosive material used in this process. The twin towers consisted of two multi-storey buildings, one 34 storey and one 32 storey. While it was also feared that the builder would have built these towers up to 40 storeys if the court order was not received on time.
The multi-storey building was constructed unfollowed the rules, while the buyers of Emerald Court also fought a long battle against it at their own expense. After the long battle of many years, the multi-storey building was demolished in just 8 seconds and now it has remained confined in history. For the first time in the country, such a tall building built in the twin tower was demolished. To demolish both buildings, 3,700 kg of explosives were used in 7000 halls. The estimated cost of demolition of Supertech Twin Towers is about Rs 17.55 crore.
The collapse will last for nine seconds, according to the project engineer. It will take about 12 minutes for the dust to settle, depending on the wind speed. About 55,000 tonnes of debris will be generated, and it may take as much as three months to clear it. The debris will be dumped at designated areas.
The explosion is expected to trigger vibrations in a 30-metre radius for a few seconds. The magnitude of these vibrations, according to officials, may be about 30 mm per second - similar to an earthquake measuring 0.4 on the Richter scale. Noida's structures are built to withstand earthquakes measuring up to 6, say officials.
About 7,000 residents of the area have been moved out. Gas and power supply in the adjoining buildings have been suspended. They will be restored by 4 pm, and residents will be allowed back in by 5.30 pm. Police have asked residents to wear masks indoors when they are allowed back into their homes, owing to the dust caused by the blast.
