With preparations almost complete, the demolition of the Supertech towers should meet the postponed deadline. The twin towers in Sector 93 A in Noida will be demolished on August 21, with a cushion period ending a week later. An extension order was granted by the Supreme Court on May 17, Noida Authority officials said. The demolition was to take place on May 22.
Edifice Engineering, the company in charge of the demolition, is currently drilling holes and wrapping pillars, beams with geotextile material to minimize the impact.
“The process is almost 87% complete. We make holes in which the charges will be laid. We also knock down structures between the towers. The size of the disposed debris has also been increased. A few days will be necessary to establish the charges which will be the last step. Demolition on the set date is on track,” a source said.
According to the sources, the company will need 21 days to install explosives in the beams. Once detonated, the charges will cause the building to implode on itself. Debris and geotextile material will ensure that the concrete does not split and the impact is reduced to a minimum radius.

The company is also identifying areas within 50 meters of the demolition site and will submit information about them to Resident Welfare Associations of owners of Emerald Court and ATS Village Apartments, officials said.
A test blast vibration report will also be submitted by Edifice Engineering to GAIL Ltd. and CBRI by June 20, officials added.
A test explosion was carried out in April to determine the amount of explosives needed for the main explosion.
The Supreme Court, on August 30, had ordered the demolition of the twin towers within three months, for violation of the regulations on the distance between the buildings. Edifice Engineering partnered with South Africa-based Jet Demolition to prepare the blast plan and execute the blast.
