    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.

        Interesting/macabre to contemplate industrial accidents during construction. The exact number of fatalities seems to be somewhat difficult to track down, but the record here (broken down quite a bit) suggests the number was about 100 or so: https://www.usbr.gov/lc/hooverdam/history/essays/fat1935.html …

        That's an extraordinary (& incredibly tragic) number - one hundred or so people who died due to falls, machinery accidents, in blasts, heat etc. Heat prostration alone was 13(!) people.

        Does anybody WANT to build a Hoover Dam equivalent today? I can’t think of a single construction project that is at all exciting.

        That strikes me as a need for an imagination booster shot! :) How’s this? https://en.wikipedia.org/wiki/Great_Green_Wall …

        The same forces that can achieve such goals struggle to figure out what the goals should be. Top-down societies can do amazing things and amazingly wasteful things. They struggle to take account of what might have been and are prone to corruption.

        But many of the projects were not top-down in that sense and I don’t think such central orchestration is a precondition. Walt Disney built Disneyland in a year.

        A recent obsession of mine! Two recs for you: https://www.amazon.com/Construction-Hoover-Dam-Department-Interior/dp/0916122514 … And https://www.pmi.org/learning/library/project-management-knowledge-work-7148 … Interestingly, the Hoover Dam was the creation of six companies that merged because none had the budget or talent to do it alone. Was literally named the Six Companies 🤓

        Not to mention the 30 years of political negotiations and surveying that happened before construction! I very much enjoyed this book about the process: https://smile.amazon.com/Colossus-Turbulent-Thrilling-Building-Hoover/dp/141653217X/ref=sr_1_1?keywords=colossus&qid=1571933912&s=books&sr=1-1 …
