^^^^ This is how they dismantled the old WA Museum building in Northbridge, could not explode it cause there was a few heritage listed buildings around it. They used a big crane to get a small excavator on the flat roof. Would have been a scary job to operate on that roof.
excavater with a rock breaker on it slowly demolishing the building around it.... im just not seeing it....
ive ripped up my share of slabs and cut down god knows how many columns, was the digger permanently supported by the crane? its not like jackhammering a slabs gonna make the whole ****ing thing collapse and **** theres just to much steel thatd all have to be cut... there is something wrong with my eyes i just cant see it.
now you drop a dozen goons with steam jacks and a bunch of quick cuts (pretty sure there is some push cutters aswell (like a lawn mower but vertical disk) ) and now that i can see happening relatively safely and well. gonna need a big ass compressor but easily liftable by the crane.
what era are we even talking here felix?

Yep, I saw a similar thing done in Mackay when they demolished the old water tower beside Nebo road.
Can someone tell me what they do with all the rubble from the excavator, also what happens when he gets to the next floor does the crane have to lift it down this would take forever

Where we are headed here in the U.S. 
Wow, unisex, just like the one at my house! 
If it doesn't look like this I don't have a problem with it
they generally push the rubble down the lift shaft,then when about half the floor they are on is gone the machine uses it's arm to lower itself to the next floor simple really oh and a bobcat cleans the rubble out of the shaft at the bottom

im still not seeing it ive broken up slabs with a backhoe and rockbreaker. there is stressed steel in the suspended decks. not to mention its all tied off to the columns etc. the buldings they did this on must not have been built the way they make them today because at some point your just going to end up with a ****load of steel floating around with boulders of concrete stuck in it. i suppose the operator can jump out with a guilitine every now and then but its just all so much of a **** around.
anyways multiple people say theyve seen it done here so must be true i just think itd be cheaper and safer to drop a dozen goons with jacks and cutters and take it apart that way. its surpriseingly quick when you dont have to cut to a depth etc and just need to destroy it all

You break the concrete from the beams, then oxy cut n crane down. Break the floor through then go down to the next floor n repeat n fill the lift shaft with rubble. Until you're down low enough then put a 70- 100 excavator on a 3-4 story high pile of rubble. Grab a donger... a piece if C Section on the excavator n start tearing it down. That's from my experience at PT Building Services.
Cauncy, care to add anything?
Also I'd appreciate RPMS INPUT!!
