So it was the contractors' fault. What then? It seems that, if someone isn't watching EVERY MOVE done by everyone on the project, and correcting errors as they go, there's always going to be a significant negative impact.

What really happened here? Did the track vehicle operator accidentally smack into a piece of the pipe one day when he was tired, and then not report it so as not to get reprimanded? Did no one see the damage during installation? This kind of crap is disgusting to me.

Agree 100% - this sounds to me like a lack of proper engineering/build oversight by a prime/general/project manager. Someone should have lost their job over this!

It would be nice to see a follow-up article looking into the particulars of the story to answer the burning question: "How did this happen?"

80% of minimum yield strength doesn't provide much of a safety margin.

Hopefully it will not be allowed in future even with a 'special permit'.
