What is implosion, the demolition method by which Supertech towers will be brought down
The Supertech twin towers will be razed to the ground by demolition experts on August 28. They will use implosion and gravity to achieve the task.
In Short
- Edifice Engineering along with Sout Africa's Jet Demolition are drilling holes in the building
- Implosion is one of the many methods employed by demolition experts
- The 30-storied buildings, when they collapse, will lead to a huge pile of debris
As 3,500-kilogram explosives arrive in the city, the work to bring down the Supertech twin towers is going on in full swing. Demolition experts are working alongside engineers to tactfully demolish the illegal structures that stand tall nearly 100 meters from the ground. The demolition is scheduled for August 28.
Edifice Engineering along with South Africa's Jet Demolition are drilling holes in the building to reduce it into a pile of debris after the Supreme Court's directions. The company was selected jointly by Noida and the Central Building Research Institute, Roorkee.
Razing a multi-storied building from the ground up is not an easy job and it requires precision planning, that takes in information to avoid every chance of collateral damage to nearby properties and people. Demolition experts will employ the method of implosion to swiftly crush the building onto itself.
WHAT IS THE DEMOLITION METHOD IMPLOSION?
Implosion is one of the many methods employed by demolition experts to rage a building, structure, or construction. It is employed when you want the structure to collapse inwards and onto itself. While it requires explosives and detonators, it's not simply just setting the charge and punching the detonator triggering a blast.
It also relies on gravity for the building to collapse in a pre-determined pattern. For it to happen, engineers will have to tactfully remove the supporting structure of a building at a certain point that brings it down upon itself. To do so, explosives are drilled into key components of the building that support the structure at different levels from bottom to top.

The support structures include columns, beams, and slabs that hold the building in its entirety. The explosives are then detonated on the lower level and, in a step-by-step manner, the charges go off from the bottom to the top. This sequential order of detonation results in the building collapsing on its own footprint or along a predetermined path.
MEASURES TAKEN TO AVOID COLLATERAL?
The 30-storied buildings, when they collapse, will lead to a huge pile of debris and shards of concrete flying outwards that could damage not just properties in the vicinity but also people in the area. To avoid such an issue at Supertech, four buildings in the vicinity will be covered in a layer of geotextile fabric.
To avoid any injury to people from the debris and huge cloud of dust that will rise from the implosion, over 5,000 residents of the nearby Emerald Court and ATS Village societies will be evacuated. Nearly 1200 vehicles are to be removed from the premises around the twin towers.
Meanwhile, the Noida-Greater Noida Expressway, which is close to the twin towers, will remain shut for vehicular movement from 2.15 pm to 2.45 pm on August 28.
WHY ARE SUPERTECH TOWERS BEING DEMOLISHED?
On August 31 last year, the top court ordered the demolition of the towers under construction within three months for violation of building norms in "collusion” with NOIDA officials, holding that illegal construction has to be dealt with strictly to ensure compliance with the rule of law.
The Noida authorities had received a rap on its knuckles as the top court pointed out multiple incidents of collusion of its officials with Supertech Ltd in the Emerald Court project and violations of norms by the realty major in the construction of the twin towers.

The top court had directed that the entire amount of home buyers be refunded with 12 percent interest from the time of the booking and 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 adjoining the national capital.
