In Afghanistan, host country national did the work, and the military QA/QC signed off after completion. KBR employees were only there to monitor the hajii’s.
Not so, at least not in '06 and '07 when I was there. In the case I'm talking about, I personally know the guy who did the electrical work. HCNs did things like take out trash, clean latrines, wash dishes etc. They also served as translators. I never knew of any HCN doing anything like electrical, plumbing, water treatment, carpentry, food prep, or any other job requiring any kind of specialization. Just general labor and translation.
Military QA/QC did not maintain "direct" supervision over much of anything. They came around and looked things over once in a while, maybe once a month, if that.
I wonder if URS has ever been investigated for shotty work.
