ACI 117 Tolerances does not recognize FF/FL on elevated decks; ASTM 1155 FF/FL Testing Procedure only references slabs on ground; Your slab-on-ground and slab–on-deck specs are usually the same; The steel on your deck is not required to meet flatness or levelness expectations; These facts can help protect contractors.
F-numbers provide architects and contractors a method of determining the flatness and levelness of a concrete floor slab. They are calculated using the standards set forth in ASTM E1155, which is the Standard Test Method for Determining F F Floor Flatness and F L Floor Levelness Numbers.
Similarly, no FL levelness tolerances will be applied to any unshored elevated construction. The general conformity to design grade tolerance set forth in Paragraph C above will apply to unshored elevated slab constructions, but in all such cases, the tolerance will be increased to or - 1-1/2". E. Testing
There is no question that obtaining floor levelness F-numbers FL of 20 or higher on elevated slabs placed on cambered steel framing is a compli ed task. There is an old saying, “the impossible is hard until someone does it.”
The effects of equipment, planters, or other movable objects present within the test area should be considered. Note 1 — Potable water weighs approximately 1000 kg/cubic m 62.3 lb per cubic ft at 22 C 71.6 F or 1 g/cm 2 /cm depth 5.19 lbs/ft 2 per in. depth .
An elevated deck is one with a top deck elevated eight to ten feet in the air based on the height of the home’s walls.

A standard single-level raised deck needs only four footings parallel to the house, but the extra footings are necessary on this deck to handle the additional weight of the roof and future remodeling project structures.
Uniform Load Test: The top rail must be able to sustain 125 lbs of force applied horizontally or vertically. Concentrated Load Test: The top rail must be capable of holding a point load of 200 lbs of force applied to the mid span, on the side of a post and on top of a post. A safety factor of 2.5 is usually added to the testing.
What are F-Numbers? ACI 117 is the industry standard for specifi ion and measurement of concrete floor flatness FF and floor levelness FL commonly referred to as F-numbers. The F-numbers identify and control floor characteristics which are critical to the floor’s usefulness. A higher F-number always denotes a better floor. Floor Flatness FF refers to the bumpiness of the floor while ...

A deck failure is any failure of a deck that could lead to injury, including rail failure, or total deck collapse. There is no international system that tracks deck failures, and each is treated as an isolated event, rather than a systemic problem.
