The problem with that "solution" is that it totally distorts the concept of a safety factor. The point is to demonstrate that a structure may built with more supports than are absolutely physically necessary thus offering redundancy- a safety factor.

So you are need to decided if you want to win points or do you want to your students to understand the concept of a safety factor.

Why are we doing this?

As David notes, the important result for M09 is that the Test Building ends up "Independent and Supported only by the blue beams”. How it gets there doesn't matter.

In regards to Mission 9 Safety factor that states: If the Test Building is Independent and Supported
only by the blue beams, and some beams have been knocked out at least half way.

I have seen some YouTube videos of teams that completely lift the test building off the blue beams, knock over the blue beams and then lower the building back on top of the beams that are now knocked over. Is this allowed?

It does seem to meet the criteria of “ Independent and Supported only by the blue beams”.
