A.F.F.

(pronounced like the initials: ay-eff-eff)

These three letters represent a four-word phrase: above the finished floor. This acronym is used in keynotes and within construction drawings to let contractors and tradesmen know how high something should be placed above the floor once any material(s) has been added. In other words, this distance should not be from the bare concrete or sub-floor, but from the top of the parquet, terrazzo, or porcelain tile. Somewhere on a general note within the drawing package the interior design must noted if the distance given is to the center, the top or the bottom of the item being placed. For example, a designer might note that top of a bank transaction counter on the designated accessible route is 36” A.F.F. or that center of all electrical outlets should be at minimum 15” A.F.F.
