Correct me if I'm wrong, but wall-building happens pretty much the same way every time. There are building codes and whatnot. The builder has built the exact same wall many times before.
Sort of. If the wall is built in a cold weather climate, the mortar mix is different than that of a warmer climate. Some walls are built to hold a load from the top, others may be built to hold back a load from the side. In the latter case, you'd probably want to use rebar and concrete to fill the voids (assuming it's block and not bricks). The differences may be more subtle than code, but my point is not every wall is built the same way.
