Demolition

Demolition is a dirty, dangerous job. I did it once for a week before I quit and I hated it.  Lots of manual back breaking work, dust and occasionally asbestos etc l.  Hate it!!!
Lucky the crane crew comes in after the demo work is done, usually as the excavation team is just finishing up.

In the states and other countries however they allow 'wrecking balls' which are banned for use in Australia :(
It looks like great fun (Im kinda jealous) but what can you do. 

You do need a much higher capacity crane than just the wrecking ball weight to allow for the swings which would move the working radius all over the place.

Most demo work in Australia is done by long reach excavator after labourers strip the building of asbestos and recyclable goods such as hard wood and copper.
