This study focuses on controlled implosion, a novel demolition technique to raze large structures at a reasonable cost and short time duration. Implosion is the controlled placement of explosives and timing of their detonation to cause a structure to quickly collapse in on itself with the least amount of physical harm to its immediate surroundings. This demolition technique was used for the deconstruction of the unlawful Supertech Twin Towers in Noida, India as per the Supreme Court verdict. The UK company Vibrock estimated the intensity of vibrations likely to be created when the building hit the ground based on the blast implosion plan details and the type of soil. Aster-2, a B + G + 12 storey, neighbouring structure just 9 m away from the tower to be demolished was analysed to ensure its safety due to touchdown vibrations resulting from demolition. Aster-2 was modelled in ETABS software and subjected to different loading conditions including blast-induced vibration and earth quake loadings. The comparison between behaviour of structure under blast loading and seismic loadings is presented, and the safety of the structure is evaluated as per codal provisions. The findings indicate that the structure is safe under the blast loading induced. Crack meters were installed to monitor the variation if any after the blast and it was found that structure didn’t had any additional damages due to the implosion. The vibration was monitored using geophones at the basement level of Aster 2 and the peak particle velocity noted was well within the permissible limits.
