Noida's Supertech twin tower demolition: Black box, red bulb, green switch — last 60 seconds before blast
NOIDA: Sharp at 2.30pm on Sunday, Chetan Dutta will roll a handle attached to a black box at least 10 times. A red bulb will start blinking, indicating that the charger is ready to be pressed.
Dutta will then press the green button, which will send electrical waves to the four detonators attached to it. There will be a series of blasts over the next nine seconds - and the twin towers will fall like a pack of cards.
With over 20 years' experience in carrying out explosions at various sites, Dutta has been appointed by the demolition company, Edifice Engineering, to press the final button that will set off the explosions. The entire process includes the crucial job of rolling the handle, charging the box and pressing the switch at the right time to trigger the 3,700kg of explosives packed into columns at Apex and Ceyane.

"The black box is called the dynamo. There are two wires in it, which are connected to the detonators. To activate the dynamo, the handle needs to be rolled 10-15 times," Dutta told TOI.
An exclusion zone of 100 metres has been created around the two towers. Only six persons would be allowed just outside the zone - Jet Demolition director Joe Brinkmann, who has prepared the blast design, two of his experts, an official from Edifice Engineering, a senior police officer and Dutta.
Brinkmann, called the master blaster by his colleagues, was supposed to press the final button initially. So, why Dutta?
"According to the laws of the land, only an Indian can press the button. So, I was brought into the team and I feel honoured about it. While Edifice and Jet have done all the preparations, my nine-member team and I are now responsible for the charging process. Had this been in any other country, I think Brinkmann himself would have pressed the button," the Hisar resident said.
Asked how the towers will fall, Dutta said the main job of bringing down the buildings was of the primary floors, which have been fully charged. The secondary floors, he explained, would give a direction to the demolition - so that the towers come down like a cascading waterfall into its own imprint.
"As the towers are surrounded by several residential buildings, the aim is to keep them safe," he added.
Dutta said that in each of the 9,400-odd charging holes, a delayed detonator had been placed for sequential blasting. In each of the holes, the amount of explosives ranges from 250gm to 1kg.
Mayur Mehta, the project manager at Edifice Engineering, said, "All the preparations are in place. Over the next two days, we will carry out checks. The detonators have also arrived."
