It took a year to build the Empire State Building, and 5 years to build the Hoover Dam yet current estimates for the Francis Scott Key bridge rebuild are near 10 years. Why is this? Have we regressed?
In: Engineering
In addition to all the other things mentioned it’s also a matter of money.
Empire State Building was a flagship project, with a massive workforce keeping up work 24/7. Hoover dam also had a massive workforce (some ten to twenty thousand), as the US government wanted the project completed fast (the advantages of having the dam exceeded the costs of building it quickly).
Francis Scott Key bridge is probably going to be built at a more sedate and cost effective pace.
