Flooring Flatness Analysis

About the Project
With the help of advanced laser scanning equipment, we can make precise determinations on the conformance of structural or architectural elements. Compliance with the execution parameters of floors and walls is essential to ensure the right conditions for the demanding materials. In this case, the beneficiaries of the project requested a graphic and measurable evaluation of the flatness level of the floor over which a special parquet with very high flatness requirements could not be installed. Following the evaluation, it was found that the flooring presented differences in vertical flatness, at the millimeter level, which exceeded the requirements requested by the parquet's technical sheets.
About the Process
The interior spaces of the house were scanned with the Trimble X7 terrestrial scanner, in monochrome format, at the level of sub-millimeter precision. The scanner positions were set in such a way that maximum overall coverage of the flooring could be ensured, taking into account the field conditions. From the point cloud, we built a detailed mesh of the area of interest. By processing and analyzing the mesh, vertical sections were made in both directions, in .dwg format, based on which the minimum and maximum vertical differences were measured. In addition, 2D DEM (Dense Elevation Model) graphic materials were created in which high and low areas were graphically marked.
Quantifiable Data
• Field data collection (photos and laser stations): 4 hours
• Number of laser station positions: 31
• Processing of data resulting from scanning (point-cloud, mesh, DEM): 4 hours
• Post-processing - generation of technical plans resulting from the scanned 3D model (orthophotoprojections, vector profiles, architectural plans etc.): 20 hours
