The plan which contains column size & position is called acolumn layout plan. It passes through the center or in the alignment of a column, or wall, or any demarked element to reference its position according to the grid as shown. From our discussion of construction tolerances, we know that the concrete columns can be as much as two inches closer to each other than our drawing shows.
