Installing girts is simple. Cut 3 2x4 spacer blocks to length in order to achieve the spacing required on your plans. Tack the blocks on top of the grade board, or last row of girts installed to easily align the new row. Remove spacer blocks and tack in place for next row up.
For sidewall overhang, wainscot, and eave light panels plan the on center to accommodate these options in the wall.
