Mark, I include any indoctrination, safety gear or processes in my quotes. Sure it magnifies the cost of a short job if you only go in once, but your computer/charger system can trip their safety switches and cost them downtime, and the bulk of that training, for regular employees is only done on average once per 5/10 30 years or whatever the turnout is. It guards against the visiting wanker, and I've seen them drive off tearing 240 volt lines out, rewire into lines which were already carrying their maximum, chop a 240 volt cable off by installing a guillotine over it, climb 7 metres up a shaky ladder, with no one stabilising it, then sit on the roof and paint up to and around the high tension wires coming into the factory, and the doozy, operate an excavator under 22,000 volt lines and lift the bucket which triggered off a sound like a stick of gelignite and left him rocking in the excavator for a minute or so with his legs off the floor and arms around his shoulders, cutting off our power for half a day (40 workers), and weakening the 66,000 volt line on the nearest pole which dropped off the insulator a week later and let of a bang like 20 sticks of gelignite and set fire to the pole - 40 people idle for another half day, and a fire truck call out.
