Laser Scanning: A Better Way to Analyze Concrete Slab Flatness

Most of the methods used today for conducting slab flatness analysis are manual and labor intensive. Floor flatness/floor levelness (FF/FL), a commonly used method, requires the creation of a grid on the concrete slab following a set of specifications before taking manual readings. Contractors that use the ASTM E1155 standard method for determining floor flatness (FF) and floor levelness (FL) numbers typically take a measurement every foot along the grid lines. Using this method, even small projects often require a substantial amount of time to complete the data collection and analysis. Recently, however, contractors have begun to discover a new way to save a substantial amount of time and money on their projects: laser scanning.  Continue reading…
