What’s happening?

The Supertech twin towers are literally done and dusted, and what remains at the site where they stood in Noida’s Sector 93A is a mountain of concrete rubble, That will now have to be disposed of quickly, safely, and efficiently.

In terms of weight, about 80,000 tonnes, according to Utkarsh Mehta, partner at Edifice Engineering, which was the contractor for the demolition.
In terms of volume, about 36,000 cubic metres of debris was expected to be generated, according to a debris management plan that Edifice submitted to Noida Authority on August 24.

The taller tower, Apex, was 102 metres high and had 32 stories.
The shorter, Ceyane, was 95 metres and 29 stories tall.
For reference, the Qutub Minar is 73 metres high, and India Gate is 42 metres.
The two towers together had 915 flats, but all walls and brickwork had been removed before the demolition, leaving only the concrete shell.

The demolition cost for the twin towers, located at Sector
93-A of Noida, is estimated at about Rs 267 per sq ft.
Given the total built-up area of about 7.5 lakh sq ft, the total demolition cost, including explosives, will be about Rs 20 crore.

Out of the total cost, Supertech is paying about Rs 5 crore and The remaining about Rs 15 crore amount will be realised by selling the debris, which will be about 55,000 tonnes including 4,000 tonnes of steel.

It took Rs 933 per square feet (sq ft) in construction costs and have a total built-up area of 7.5 lakh sq ft, which aggregates up to a total of Rs 70 crore.
The cost of one 3BHK apartment was about Rs 1.13 crore in the Supertech Emerald Court Project.
There were about 915 flats in the two buildings, which would have earned the company about Rs 1,200 crore.
Out of the total 915 flats, about 633 were booked and the company had collected nearly Rs 180 crore from homebuyers.
Now, Supertech has been asked to refund the homebuyers money with an interest of 12%.
“Our overall loss is around Rs 500 crore, taking into account the amount we have spent on land and construction cost, the charges paid to authorities for various approvals, interest paid to banks over the years and the 12 per cent interest paid back to buyers of these two towers, among other costs,”

The twin towers had two large basements.
According to Edifice’s debris management plan, the bulk of the debris — 23,133 cubic metres out of the total 36,000 cubic metres will be used to fill the basement.
In terms of weight, that will account for around 50,000 tonnes of the total 80,000 tonnes.
A small portion of this debris will also be used for some essential construction at the site.
The remaining 30,000-odd tonnes — 12,867 cubic metres according to the debris management plan — will have to be removed from the site.
Whatever material can be re-used will be separated and employed for this purpose.
Noida Authority CEO Ritu Maheshwari has said that the rest of the debris will be processed at a construction and demolition waste management plant in a scientific manner.

In January 2020, four apartment complexes built in Maradu, Kochi were demolished on the orders of the Supreme Court over violation of Coastal Regulation Zone norms.
The rubble left behind was around 76,250 tonnes, apart from 1,000 tonnes of thermo-mechanically treated (TMT) steel bars.
Kochi-based Prompt Enterprises, which was given the contract for removing the concrete rubble, took nearly four months to completely clear the demolition site.
The concrete chips from the rubble of Holy Faith H2O and Jain Coral Cove buildings were used to make hollow bricks and pavement tiles.
The rubble from the other two sites was used for land-filling and related purposes.
The re-use of concrete debris from demolition sites is a common practice in Western countries, and is catching on in India, industry experts said.
