you're talking months of prep work ripping apart walls, jackhammering out concrete to get down to the rebar, making weakening cuts into the superstructure in order to allow for the placement of cutting charges...
for example if you have 10 supporting members you need to sever in order to bring something down, and the building is gutted... you can remove 5 or 6 of them with a cutting torch then place cutting charges on the remaining system.
according to the link they used 85,000 charges... which seems a bit overinflated... they may have been counting the individual bags or tubes of HE as "bombs" but i can't imagine rigging a job with 85,000 initiators and then running the det wires and det cord to connect them all back to a blasting box.
also it should be noted that in most blasts you don't initiate all of them at once, they are timed with some freaky precision to allow you to use gravity to your advantage...
for example, you'd want to blow out the connections at the top of a wall which pin it to a structure a fraction of a second before you blow the bottom to allow the structure to begin to fall but then kick the legs out from under it and let gravity do the rest.
the thing is you're dealing with an amount of mass and inertial forces most people can't wrap their minds around, TBH that building fell a long way before squatting and i was shocked to see anything made by the chinese withstand all those forces. usually when you get something that big moving it's fucking over with. those structures must be FULL of tensioned rebar to remain rigid like that. i'm actually shocked to see that.
anyway there's no chance in hell this was done on the sly.
IF a whitehat production, it could be specifically to break the economy more in the area.
How easy is it to make something like this happen?
lol, it's a MASSIVE undertaking.

Thanks for the insight. That makes perfect sense.
