Sure the timing is pretty lousy, but structural testing to destruction of a completed structure is a bit archaic in this day and age. 300 meter tall skyscrapers are becoming the norm, no testing to destruction of completed structures needed. If one of those ever structurally fails, the death toll would be massive.
those structures are designed with high safety margins that will take care of modelling errors, that is allowed since are standing on ground and have minimal weight issues. A failure can be detected and fixed over time, and rarely fails, however there are several cases of wrong design that costs several lifes. Furthermore each and every single building has its own modelling, an error is limited to a single building not to thousands of planes carrying million of pax...
