My first big pour as a service tech for a concrete company was a super target in Mt Dora FL. We poured from midnight to 12 noon for a few weeks straight. The testing company was Universal engineering and they sent out the biggest idiot I have ever met. He said mud going in was 4-5 and coming out of the pump at 6-7 anyone who knows anything understands this is a physical impossibility concrete does not get runnier going through a pump but he had us testing it at both ends, he was a nightmare to the finishers as well, constantly badgering them about how to do their job. one guy bulldozed his samples on purpose, so he had to ask me if he could get access to the ones I had made. Just an all around idiot who let a very little bit of control go right to his head.
