This document defines common abbreviations used for floor levels in construction drawings: SSL refers to the structural slab level, SFL is the structural floor level, and FFL stands for the finish floor level. It provides examples of how these abbreviations may be used on structural versus architectural drawings and notes that rooms often require concrete fill to reach the finish floor level, while structural slab and floor levels are usually the same in parking areas.
