Abstract:
In December 2021, the American Society of Concrete Contractors (ASCC) initiated a study focused on laser scanning results and deliverables for slabs-on-ground to provide recommendation to Joint ACI-ASCC Committee 117, Tolerances. The article discusses slab thickness and F-numbers results from this study, possible issues with laser scan results, and provides recommendations for organization and presentation of laser scan results for a slab-on-ground.
