Earlier this summer, I received a call from a couple to demo a old R&R tie wall. Then install a new wall and steps with a block of there choice. As we talked I was explaining about engineering, grid, compaction, drainage, etc she asked, how do you know all this? I explained about NCMA & ICPI. She asked me how many walls have I built. As I informed her, None. See looks at me an said "She wants a trained experienced professional" Try as I did, Explaining that she would receive a professional Job. She found somebody else. Well as you can see from the photos she found her, "trained experienced professional"
