The demolition

A mock drill to condition the team of police, fire force, health officials and other experts for the Sundays exercise was carried out at Golden Kayaloram on Saturday evening and at Jains Coral Cove, the third building, on Friday.

Residents in the neighbourhood moved out and Section 144 of CrPC come into force at 8 am in the evacuation zone ahead of the demolition to ensure there was no untoward incident.

Ahead of the demolition, the area in a 200-metre radius of the building was kept out of bounds for people and all kinds of traffic.

In a precise sequence, over 350 kgs of explosives filled in the structures were blasted in a controlled manner at the end of the third warning siren and the concrete colossus came crumbling down in seconds, triggering mammoth clouds of dust, PTI reported.

In a few seconds, the towering building, whose interior walls had been removed in pre-demolition work over the past weeks leaving it a concrete shell, became mounds of debris.
