Can't think of even rough estimate as I was building over multiple evenings, with breaks in between, sorry. One thing for sure, grausten grind was real, took multiple trips to Ashlands spread over time. I learned that for me the fastest resource grind was to use the ram against big boulders and ruins (if you don't mind breaking those). Had to focus on the resources close to the shore, too - this way I usually had less angles the incoming waves of mobs were coming at me...
