New Delhi: The Supreme Court on Friday postponed the demolition of Supertech’s illegally constructed twin towers on the Noida-Greater Noida Expressway by a week till August 28, and asked the Noida authorities and Edifice Engineering to strictly follow the recommendations of Central Building Research Institute ,CBRI), Roorkee.
Accepting the report of the Council of Scientific and Industrial Research (CSIR)-CBRI, represented through Chief Scientist DP Kanungo, a bench of Justices DY Chandrachud and AS Bopanna allowed the request of Senior Advocate Ravindra Kumar on behalf of Noida and an additional window of seven days – 29 Aug-4 September – provided for completion. Two 40-storey buildings are demolished if the demolition is delayed on 28 August due to technical reasons or certain observational circumstances such as weather conditions.
Appearing for Supertech IRP, Senior Advocate Devdutt Kamati informed the court that though the hands of the IRP are financially tied by the orders of the NCLT, it has paid Rs 70 lakh as fees to CBRI on the orders of the court and requested the SC to make provision for additional payment Which will have to be done from Supertech Fund for future costs. Regarding the destruction.
The CSIR-CBRI in its report to the Supreme Court said that the debris of the demolition of two towers is estimated to have piled up to a height of 11 meters, which is about four storeys. “The construction and demolition waste management plan (as yet approved by the State Pollution Control Board) has been submitted to CSIR-CBRI building On August 9, the average height of the post-demolition rubble pile will be around 11 meters (according to proper calculations).
“In view of this, barricading in the periphery of the rubble pile can be done up to a maximum height of 12 meters for post-demolition activities and protection of the surrounding habitat. If deemed fit by the Joint Inspection Team after demolition, the geotextile fabric removed from adjoining buildings after demolition may be reused for this purpose,” the report informed the court.
“Upon completion of the demolition work, a joint team from Noida, CSIR (CBRI and Central Institute of Mining and Fuel Research – CIMFR), and Edifice, along with a representative of the local police, will first visually inspect the debris and surrounding buildings. Allowing the vacated residents to return and occupy their apartments,” indicating that the vacated residents of the surrounding areas will have to stay away from their flats for at least a week after the date of actual demolition .
CBRI said it had given permission to charge the twin towers with explosives on August 11, subject to the following assurances: a) submission of a structural analysis report by Edifice before August 15; b) Structural audit report and completion of reinforcement/repair/retrofitting measures by Supertech at least three days prior to the date of demolition for the three nearest towers of Emerald Court; and c) Structural audit for four towers of ATS village within 50 meters of the blast radius at least three days prior to the date of demolition.
“These three actions are imperative to ensure adequate data base and preventive action for the safety of neighboring structures, and assurance and compliance to this effect should be obtained by CSIR-CBRI before the charging of buildings to be demolished begins. In particular, the reinforcing process associated with concreting for the Emerald Court towers should be taken up on priority to achieve the desired strength prior to demolition,” the report said.
“The data generated from the action will be reviewed by CSIR-CBRI within 24 hours of each submission. After review and found to be in compliance with the desired strength parameters for safe demolition, the final demolition may be authorized to proceed,” it said.
The CSIR (CBRI & CIMFR) team proposed to monitor ground vibration and air pressure (AOP) apart from visual monitoring of the demolition process and inertia monitoring of towers using high speed video cameras (RGB and thermal sensors).
