FF and FL Numbers - Floor Flatness and Levelness - archtoolbox.com
F L numbers provide information about the concrete floor's levelness. Levelness depicts how closely the finished floor matches the intended slope indicated in the design documents. Elevation differences are measured every 10-feet within 72 hours after the concrete is placed and those measurements are entered into a calculation to determine floor levelness (F L ).
Achieve Floor Flatness and Levelness with F-Numbers – Somero
To find the floor flatness using F-numbers, you measure the elevation differences, d, between points on the floor, one foot part on a straight line. You calculate the differences, q, between all of the adjacent d values. Then use the mean and standard deviation of the q values to determine the FF number.
This system identifies two numbers: FF (floor flatness) controls local surface bumpiness (or waviness) by limiting the magnitude of successive 300 mm (1-foot) slope changes. The other, FL (floor levelness) controls overall levelness by limiting differences in the
