Demolition of Supertech twin towers poses challenges for India

02 Sep 2021 CW Team

Supertech's twin tower in Noida will be a big challenge because no building of height 32 storeys has been demolished in India so far, as per the experts.

According to experts, it has little expertise or research in such buildings demolition with the concept of skyscrapers fairly recent in the country.

Supertech planned to construct 40 floors each in Apex and Ceyane, out of which 32 have been built till now. This demolition process will present a stiff logistical challenge due to the buildings in the vicinity. A neighboring building in the same Emerald court compound is divided by a narrow driveway from the twin towers walls.

Experts said implosion is the preferred technique for densely populated regions. In this method, small explosive devices are placed at building various locations in such a manner that when detonated, the debris falls within the premises, though there are several techniques for such tall structures demolition.

While such demolitions processes have been executed globally and on a smaller scale in India, it needs much preparation. Additionally, in the twin towers case, preserving the structural integrity of the neighboring towers within Emerald Court will be a challenge.

In India, there is hardly any example of the skyscraper demolition process or related research, and the Noida authority will need to hire foreign consultants as experts, said Divya Kush, president of the Indian Institute of Architects.

Experts said debris from an implosion merely affects nearby buildings, but dust clouds may remain for a long time depending upon the airflow.

An Edifice Engineering partner, Uttkarsh Mehta, said that the Noida's entire demolition process would take over four months from planning to clearing of debris, he estimated.
