Thirty below for weeks on end, a frost line of about a million feet. And some heavy tanks filled with thousands of gallons. Helicals are right at 90 ft deep.
We had a big pad all formed and re-enforced and ready to pour at the Shuttle launch complex. 2 days before we were scheduled to pour that 600 cu yds of concrete the superintendents get a change order from USAF/NASA and they say "Pour it! We don't get paid until it's completed. We'll tear it out before it gets cured." :wtf: :lol: Our tax dollars at work.
