An integrated methodology of NDTs for the characterization of stone pillars and columns

Cultural Heritage diagnostics is crucial for targeted protection strategies, preserving artifact integrity and understanding materials and conservation status. The proposed methodology integrates Non-Destructive Techniques (NDTs), laser scanning, and GIS elaboration with macroscopic and minero-petrographic analysis. Using Sonic Velocity and Schmidt Hammer tests, it provides insights into structure thickness and surface properties, aiding in a comprehensive understanding of overall condition and critical areas. 3D models visually represent results, facilitating identification of areas for closer examination. Applied to XVI century loggia columns in a Florentine building, this approach supports restoration efforts in line with the Venice Charter conservation principles.
