Urban Infrastructure

Urban infrastructure refers to the physical systems that support a city — transit, water, power, public buildings. A recurring theme in the wiki is the enormous gap between historic construction performance and modern project costs and timelines.

James Surowiecki benchmarked this gap in May 2022: New York City was replacing eight escalators and upgrading fire alarms at a cost of $62 million — roughly 1/13 of what it cost in today’s dollars to build the entire Hoover Dam. The replacement project was scheduled to take until Q2 2023, about as long as it took to build the Empire State Building. See Public Construction for the broader pattern.
