Hoover dam was a lot of separate pours. They allowed the concrete to dry before pouring the next level.

82 million lbs (who writes this stuff ... I thought concrete was measured in yards ... ) of FOOTER ... big deal.

The vibrators had the biggest and hardest job

Now ... if they were going to pour 73 stories of WALL ... now THERE'S a Guiness World Book of Record !!
