The abbreviation "FFL" stands for "Finished Floor Level" in construction terminology. This term is critical in architectural and engineering documents as it indicates the height of the finished floor surface in relation to a specific datum point, usually the foundation or ground level. This information is essential for ensuring proper alignment and consistency across different elements of a building, such as door heights, window sills, and other installed features.

Understanding the finished floor level is vital for multiple aspects of construction, including flooring installation, drainage considerations, and overall building design. It helps contractors and builders confirm that the final floor surface will be at the correct elevation, facilitating appropriate access and the integration of various systems within the building.
