How exactly does a planned demolition of a building work? How do they pick where to put the bombs?

Question

I’ve always been curious. How do they know all these things because the buildings always fall down nearly perfectly?

In: Engineering

Answer 1

They’ve studied structural engineering and demolition for many many years in order to know where the load bearing beams are and how a building is constructed (based on the blueprints), so they know where to place the explosives and in which order to detonate them so that the building collapses in on itself.
