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
You are wrong in citing as an example the Hoover Dam. Planning for the Dam started in 1922 and the Dam didn’t finish until 1936. The US passed funding for it in 1928, and construction didn’t start until 1931. They need to remove the wreckage. Plan the bridge. Find the money. Put it out to bid. Assemble the materials and personnel. Deal with permitting, environment, and safety concerns. Then build it without blocking river traffic.
