Noida: exercise mammoth lowered twin towers in compounds court emerald Supertech, while ensuring the safety of all other buildings in the densely populated, will take place in four phases which will include a survey of the structural of all buildings within a radius of impact and “pre-attenuation” tower so that they explode within the perimeter so the allegations set out.
Sources in Edifice Engineering, the company that commissioned the demolition, said it also plans to take out third party insurance cover of Rs 75 crore-100 crore to indemnify houses and other structures within a radius of 50 meters from the twin towers.
93a in the sector if there is structural damage due to the demolition of the tower.
Residents in the vicinity, especially those near the village Greens Greens, have been airing their concerns about the demolition and its impact on the structural integrity of their homes.
RWA his head Bharat Bhusan on Monday told TOI he had been seeking details of the demolition plan Noida authority but not yet received.
Apex and Ceyane, two towers that are uninhabited, were destroyed on the orders of the Supreme Court, which on August 31 last year upheld the Allahabad High Court order to reduce them, holding that the tower was built to be a violation of law.
The Emerald Court Rwa has started a legal battle against the Twin Towers in 2012.
Sources said the types of explosives to be used for demolition will be determined so engineers and technical experts from the Edifice, visited the Organization of Petroleum and Explosives Safety (PESO) office in Agra in time week.
In addition to seeking approval of the organization to carry out explosions, Peso, the nodal agency for matters in which the explosive action and Petroleum Act applies, will also provide a list of explosive storage magazines in the region.
Edifice explosives Engineering will choose which one to use only after checking the inventory available in the magazine.
Far from the location where they are produced, the magazine is a building or structure that is designed specifically for permanently storing explosives.
Ammonium nitrate, nitroglycerine (dynamite) and trinitrotoluene (TNT) are some of the options on the table.
“The quantity will be decided only after we know the type of explosive material which will be used for implosion.
Our meeting with the PESO will provide clarity.
Until then, no one can say.
We will visit the magazine at Agra and other parts of the NCR to examine the options , “said Uttkarsh Mehta, partner at Edifice.
Before the demolition occurred, most likely in May, the extensive preparation required.
In the first phase of preparation, the engineers will survey the demolition site and two towers measuring.
Experts will also examine defects, cracks and deterioration in the level of nearby buildings.
“Basically, we will conduct a structural audit in the area of impact and see whether the strengthening of the existing structure is needed,” said Mehta.
Apex and Ceyane pre-attenuation to ensure the collapse of the tower will be the next step.
For this, engineers will identify the columns, pillars and beams for removal.
Cantilever beam supporting the two walls will be first imposed.
Shear wall will present challenges.
A preliminary survey has revealed that the shear walls were built on each floor apex height of 100 meters (33 floors) and ceyane 97 meters (32 floors) in length 12 meters and width of 3 meters.
Designed to accommodate lateral and increase resistance to seismic shear walls should be cut strategically on each floor to make sure the structure is left flowing in methodology ‘explosive waterfall, which is being employed, in which the towers collapsed and debris collecting in a pile at the bottom of the regulated perimeter.
Shear walls will generate the maximum amount of steel that can be saved.
It is estimated that about 7,000 holes should be drilled in the gap of 1 meter to 3 meters in two buildings to accommodate the explosion.
Other preparatory measures would include a check for hazardous materials such as asbestos, which can cause a health hazard and should be taken before the explosion.
Engineers will also establish a perimeter insulation to absorb shock and to minimize noise and dust pollution and vibration caused by the explosion of the tower.
