Abstract:
We’ve just been informed that the owner is rejecting a floor we’ve recently completed. The basis of the rejection: flatness/levelness measurements taken along one sample measurement line are below the specified minimum value. When minimum FF/FL values, as defined in ACI 117-061 or ACI 117-90,2 are specified for random-traffic floor surfaces, do those minimum values apply to each sample measurement line, as defined in ASTM E1155, 3 or do they apply only to the composite of the measurement lines?
