In residential construction, placing anchor (j bolts) for the sill plate, I have always read that it's best to stay towards the outside edge of the foundation and face the J portion towards the interior of the home. For an 8" thick concrete wall, I have always used ~3" in from the edge. This allowed a 2x6 plate to have the anchor be about 1/4" off center of the board.
Wondering how you guys do it, and if there is a better way. I always try to get the concrete guys to provide 10" instead of 8" bolts, and they are typically 5/8" diameter.
Also - Do you actually preset the anchor bolts in blocks of wood or rebar cages, so that the hook part of the J slips under the top horizontal rebar?
