Trimble X7 with FieldLink for Floor Flatness and Levelness. See how to create ASTM E1155 reports in the field. Know where your lines were sampled from and have the data registered and referenced to a coordinate system, model (DWG, IFC, SKP, RVT, NWD,etc) or even a PDF.
See earlier videos for using the X7 to
-find high/low areas on wet concrete.
-compare scans/as-builts to models/pdfs
-create surface reports with cut/fill amounts and grid line samples
