Laser scan data crunching speeds slab flatness/levelness measurements

Sources: ClearEdge3D Inc., Manassas, Va.; CP staff

Software unveiled at World of Concrete 2019 generates floor flatness and levelness figures from laser scan data, and visualizes wet or hardening concrete slabs’ high or low areas with elevation or deviation heatmaps, contours and grids. The new Rithm for Autodesk Navisworks version promptly delivers analysis reports compliant with ASTM E1155, Standard Test Method for Determining FF Floor Flatness and FL Floor Levelness Numbers. In contrast to the multiple-day process typical of current FF/FL measurement practice, developers cite the program’s capacity to reveal E1155 numbers in under 15 minutes.  

Set for February release, the software spans tools and technology of a) Topcon subsidiary ClearEdge 3D, whose EdgeWise software utilizes automated feature extraction and assistive modeling to speed 3D modeling workflows for architectural/engineering/construction users; b) San Francisco-based Rithm, whose Inspector App creates floor flatness reports for concrete or general contractors; and, c) San Rafael, Calif.-based Autodesk Inc., Navisworks project review software developer. 

In a joint announcement at the Las Vegas Convention Center, ClearEdge 3D and Rithm assessed the software’s potential to give “users the opportunity to perform FFL analysis in-house, which allows them to work with their own tools and team, therefore reducing quality assurance and reporting costs … Besides making dry concrete analysis faster and more insightful, contractors can also check wet concrete for deviations while it’s still workable. This new approach to FFL analysis allows them to reduce costly rework and identify mistakes faster.” — www.clearedge3d.com; www.rithm.io
