Visiting the Hoover Dam feels to me like visiting a rift into an alternate timeline—one in which we attempt enormous, absurd, starry-eyed projects… and achieve them, under budget and years ahead of schedule! I’d love to better understand the forces which made that possible.

Our tour guide suggested the true number was probably closer to 400; in order to avoid paying death benefits, they didn’t count any deaths which occurred off-site (e.g. someone collapses from CO poisoning and is taken to hospital, cause of death declared as pneumonia)

Maybe we can get the best of both worlds if we just move to doing more projects like these through heavy teleoperated robotics haha

Looking around a bit more, the Oroville Dam: (a) is much, much larger (it's higher, and several times the length); (b) also took just a few years to build; (c) had a much lower number of casualties (~30); and (d) was built in the 1960s.

Dangerous to infer too much from just two examples. But I wonder if we simply got a lot better at safe construction from the 30s to the 60s?

Would be great to understand the trend over time. Many more than that died building the transcontinental railroad in the US (although that was a bigger project). Thousands died building the Panama Canal (mostly from improperly handled dynamite, as I recall).

In fact, *tens* of thousands died *failing* to build the Canal, in a previous, abandoned effort by a French private company in the late 1800s (before the US Army stepped in to build it in the 20th century). A lot of those were from the tropical diseases of malaria & yellow fever
