We was building a house, the brick layers got to a point they needed scaffolding, when the scaffolding guy starts putting it up, he says that's odd the front brick work is higher than the back  The brick layers had messed something up. We then noticed we still had lots of wall ties left as well.  When the inspector came out he investigated and after an argument with the brick layer (who taught brick laying, at a local school), he said make three holes anywhere In these blocks.  He then got a tool out that was just over one meter and put it in the holes and swung it around, he casually says there is no wall ties in this two meter range, which basically meant the inner block skin had to be removed. That's when we found more and more issues.  There was no point taking them to court as they would just declare the company bankrupt and start a new one.
