How'd they get those excavators up there?

[deezler]

Thats insane. If the building is weak enough to be clawed apart with a basic excavator, how is it also strong enough to support the excavator while its working? So the operator is up there driving around on a pile of shifting rubble, with no safety net whatsoever.

This is how we do it in the US

Didn't the Chinese invent dynamite or gunpowder?

I saw buildings going up by the dozens in Beijing. Seemed to be mostly prefab stuff stuck to a core.
I would not want to live in one, Gov say they go for 600,000 USD each, but gov allocates to families, who pay next to nothing, so workers don't live on the streets.
Though we saw work crews that lived in large tin shacks on the building site like we would use here for storing sand or rocks.

From that article, think it says it all:
The situation is even more problematic in China, where a combination of lax workplace safety laws and shoddy construction has given rise to a world where buildings are slapped together, sold, condemned and torn down – often within just a few short years. Sometimes the buildings don’t wait for the demolition men: what goes up too quickly, often comes down even quicker.

Think about how the Miami collapse was reported, now think if this was a commonplace event and the news was not allowed to say anything.

It don't always go as planned though...

It does if CDI has the job.
They have a YouTube channel full of their work. Each video is only 3-4 minutes.
Everything from whole apartment complexes to bridges, radio towers, windmills and nuke cooling towers.

According to the video I watched it also causes a lot of dust and minor debris. In a congested city that creates it's own set of problems and cleanup logistics.

Chinese workers are disposable

If one gets in the way, wash off the leftover bits and another guy is waiting to take his place. Probably done between press cycles. If the worker is still alive you fire him and kick him onto the street.

There's a sad situation.

An industrial area I would visit in Shacow, Schenzen, China, all the buildings cement work was mixed with the salt water from the shoreline. Guess what.... Buildings were crumbling. Typical of all Chinese manufacturing. AND the USA is dependent on them. Very sad

Why excavators and not blasting? The excavators are used because they have far less fugitive dust and debris.

How do they do it? They collapse part of a floor and transition onto their debris pile/pad to work the rest of that floor. I’ve seen it with a three and four story building. it would be the same operation, just a longer duration.

How do they get up there? Heavy lift cranes.
