I was rethinking the extent of my experience with timber walls. I am going to start doing work in an area where timber walls may be options. Now I've built several but nothing over 4' high and we just put dead-men in as we saw fit (plenty of them for sure). At what point do you stop with deadmen and use geograde? At what point is an engineer or inspector needed? I have the same question towards block walls because height experience is almost the same.
