Used to be when building bridges the rule of thumb was one worker would die for every $1million in project cost. I think there was also a metric for tunnel boring projects, how many dead per mile of tunnel.
I seem to remember some story about the Golden Gate Bridge and nets to cut down on the deaths. What a concept, not taking a certain number of worker deaths for granted.

We hit an 8" water main once, but skated out of getting charged due to poor locates (although we did know it was there) The worst hits seem to involve large amounts of water or gas usually with gas having much higher risk of loss of life. We have crossed a few pipelines with various hazardous hydrocarbons, that depending what they happen to be running today, a break could instantly freeze solid anything within a few hundred feet.
