Notice that I am calling for a sequential mechanism.

What exactly do you mean by that?
After the initial floor collapses, the next floor underneath is hit by many times the weight of what it previously supported. It gives way and drops to the next with even more weight and momentum. So the floors rapidly collapse in sequence. This was explained in detail by the link I provided you sometime back featuring the guy from Lawrence Livermore labs. The analyst indicated the collapse would be so quick as to approach the speed of freefall. Films clearly show the floors collapsing in sequence as the collapse front drives downward. There is no universal, instant collapse as expected with planned demolitions.
