The dimensions of the dam is insane, 221 meters or 726 feet tall, 379 meters or 1244 feet long plus the base is 201 meters or 660 feet thick of concrete. To use a comparison you could build a standard four lane highway from San Francisco to New York with the concrete that was used during this project.
Some interesting facts of the Hoover Dam; A) At first the structure was called Boulder Dam (named after Boulder Canyon that was in the area) then later was named after the President at the time, Herbert Hoover
B) Nevada Boulder City did not exist until it was built in 1930 to house the workers for the dam. It had no local mayor or elected officials and was managed by a US Bureau because the land was on government property. Finally after 30 years (with the construction of the town) the control of the area was given to Boulder City, which then it was officially incorporated as such
C) During World War Two it was found out the Nazis plotted to blow up the dam. It would of had a disastrous effect on the Southern California airplane manufacturing industry with the loss of this electrical grid. After America entered the war (with the attack on Pearl Harbor) the dam was closed to all visitors until after 1945
D) The Hoover Dam was the tallest (726 feet) in the world until the Mauvoisin Dam was constructed in Switzerland (820 feet)
E) Because concrete needs time to settle from liquid to solid ( the Hoover Dam would of taken over 125 years for this process because of the amount of concrete poured on this project) the engineers built a large refrigeration system to produce 1000 tons of ice per day Then they embedded one-inch pipes within the concrete which allowed the ice water to circulate thus allowing the cooling process to take only two months to fully set, plus an added benefit it made the concrete less susceptible to cracking |
