I work for a company that routinely does civil work for electrical contractors. Not little stuff, we install the ductbanks from power plants to substations. The electrical safety stuff we have to go through to be anywhere near the high-voltage stuff is intense and expensive, but we have never had an injury or death. We do fire new guys who try to play hot-shot and don’t 100% adhere to procedure, though. There is no room for error.
It’s nice being the #1 contractor on the preferred contractors list.
