Maradu flat demolition: Date for controlled explosion yet to be fixed
Kochi: The apartments in Maradu which was constructed by violating the Coastal Regulation Zone rules will be demolished through a controlled explosion. All families who occupied the flats in the four apartments were vacated as the authority took a firm stand to implement the Supreme Court order.
A technical committee has been appointed to monitor the controlled explosion. But a final date is not fixed yet. The committee will submit a report to the authority regarding the explosion on Monday. The agencies engaged in the demolition were also directed to file a report within 15 days.
Kochi sub collector Snehil Kumar Singh informed that the controlled explosion of the flats will be carried out after examining these reports.
Controlled electronic explosion is used to raze multi-storeyed buildings across the world. Emulsion explosives are used for these explosions.
Ahead of the explosion, design of each flat will be taken to determine the load bearing point. A decision on quantity of explosives and time of explosion will be taken as per the load bearing point.
Explosives will be filled on every beam by drilling holes. Explosions will be carried out within an interval of 200-250-300 micro seconds. At first, ground floor will be demolished.
Interior walls of the apartments will be removed before the explosion. Only frame of the apartments will be demolished through the controlled explosion with a designed computer programme.
Trial of the explosion will be carried out on a small beam before the major explosion.
“Following the explosion, concrete waste will be piled up on the building spot itself. It will not spread all over the area. Mats and tarpaulin covers will be erected over the area to check pollution from the explosion. It will take only 5 to 10 seconds for the final explosion," said sub collector Snehil Kumar Singh.
Vijay Steels and Edifice demolition contractors are the major companies which are named in the list to carry out the explosion. Both companies are well experienced in the field. One company has claimed that they have razed down a 100-metre high building.
Expert engineers from KMRL, Petroleum and Explosives Safety Organisation (PESO), Pollution Control Board, PWD and local self-government department are included in the committee. A meeting of the committee was held on Saturday at Maradu municipality.
Meanwhile, an authority asserted that priority will be given for public safety during the explosion. This will be the major condition while issuing the tender. Third party insurance will be implemented for this purpose.
The technical committee will study the impacts of the explosion. They will carry out the disposal of concrete waste from the spot. The team will examine the scope of using this concrete waste for road levelling, quarry levelling and sea wall construction.
“It is assumed that ground vibrations from the explosion will not affect the nearest places. Residents close to the area will be evacuated for a few hours,” said sub collector.
At the same time, the authority has not taken a decision on demolition of the five towers at a time.
