How do you demolish a building?

One day my wife spotted several excavator machines attacking a small house on the roof top of a multi-storey storehouse in front of our window.  The small house was probably part of the elevators system, housing the machines that operated the elevator cars.  Thus tarted the demolition of the storehouse to make way for a new hotel.


Another small house at a corner on the roof top was soon also attacked.  


Some of the excavators are equipped with a digging bucket at the end of the long arm.  Some are equipped with a sort of hammer, to break up the concrete. 

Soon they started digging holes in the roof top, exposing the next floor down, which was essentially the top floor in the warehouse. 


As the walls were knocked down and the concrete were broken up, metal rods,  window frames, etc. were savaged and tied up.  

The piles of concrete were thrown down the elevator chutes.  


The rubbles were piled up to form a ramp, to enable the excavators to move down to the lower floor.  


The excavators on the lower floor then turned around and attacked the floor where they came from.


Within a few days, the roof top was completely gone.  


The top layer of bamboo scaffolding and free protective nets were also removed at the same time.  At one point, the long arm of a crane reached from the ground to the roof.  It seemed to be helping to remove the scaffolding and the net.  Perhaps the structure was too unstable to send worked up the bamboo scaffolding to dismantle it? 


It seems to take several days, up to one week, to demolish one floor.  

At this rate, it may take several months to completely demolish the whole warehouse.  

My wife and I find it quite fascinating. We are receiving a good education for free.  This is the first time that we can watch a building being demolished, without explosives, with front row seats, in the comfort of our own apartment.  From this perspective, this is great entertainment.  

We love our home.  We are praying that the new hotel will not be too high.  It is probably a lost cause.
