It's all set. The date is locked. The gunpowder is ready. Residents have been asked to stay away as the Supertech's 40-storey Noida twin towers will be demolished at 2.30 pm on August 28 in line with the Supreme Court order that found the structures were built in violation of norms. The demolition of the nearly 100-metre tall building was to begin on August 21, but the top court accepted the Noida Authority's request for an extension, pushing the exercise to Augst 28. The twin towers, which were to house over 900 flats and 21 shops, are located in Noida's Sector 93B.
