Transpower chief executive Alison Andrew says a power pylon that fell last Thursday was due to contractors removing too many nuts from bolts connecting the tower to a base plate.
This occurred during maintenance on the transmission tower and was not to procedure and it was “unprecedented and unacceptable”, she said.
I’d guess the contractors were not properly instructed. This brings a point, who were the contractors working on this? Did they have any relevant experience, or were they simply casual labour?
I’d expect all procedures to be fully documented and importantly regimented into crews. But seemingly not in this case, how the hell could this happen?
