Hi Dave,
I looked briefly through the 2002 D1.1 and didn't see any reference other than to Inspect per Table 6.1 "Visual Inspection Acceptance Criteria".
I personally like to inspect the materials when it returns from the galvanizer. This is when you can find "cope cracks" and welds that may not have been totally sealed and "started to" or "may have" torn during the dipping/pickeling processes. Plus the shiny surface shows up all sorts of defects you might not notice before.
I don't always get the luxury of inspecting the material after galvanizing, due to it being shipped directly to the job from the galvanizer.
Maybe someone else will find reference to inspecting after dipping, but I didn't in my brief search.
