How do controlled demolitions work

How in the world does someone know how to make a whole building basically crumble and not destroy building around it?

Do the nearby buildings have consequences? Will it create cracks in them somehow?

A lot of math.

Based on the size and materials, engineers can calculate exactly how strong the building components(beams, columns, ect) are. They can also calculate how the building will fail if they remove one or more of those components, as well as the effects it will have on the ground and how those forces will transfer to the buildings around it. So they do the calculations until they find a way to demolish the building in a way that doesn’t damage the structures around it.

If they do the math wrong, or don’t take all the propert factors into account, it can definitely have bad consequences for the buildings around it.
