people do all kinds of crazy things. I did not say it can't be done by a bunch of guys. I work on my car, and I bet I am not the first person that has jacked it up, then gone underneath without putting jackstands underneath. The point is, it is not safe. If you are going to be a serious construction entity you have to work safe.
I am sure you did that. It was not smart. I have done dumb things as well.
I would be willing to bet that RKT is a union shop, hence they will have to build with union labor. Their costs will at least double if they have been doing things like "a bunch of guys", on the weekend with a few beers.
