Demolition Technology

Explosive demolition technology has become most popular in the USA. High-rise office and residential blocks are brought down in a matter of seconds. Often such demolitions provide a spectacular show for the people who live and work in the area. But the actual preparations leading to the countdown could take months, such as laying of explosion charges, safety precautions around the neighbourhood.




The non-explosive method is now widely used in Singapore using hydraulic breakers mounted on excavators, which are lifted to the top floor of the building and demolishing downwards, floor by floor.





In November 2007, Kajima Corporation began demolition of its former head office buildings, which had served the company since 1968.
Kajima devised a world-first technique called the Cut & Take Down method, which enables demolition work to be done on the ground floor. By starting at the bottom, cutting one floor, and then lowering the entire building down on jacks one floor at a time, all the work can be performed safely at ground level.
