The on-site inspections successfully identified the building's load-bearing system while simultaneously evaluating, where possible, the quality and conservation state of materials and structural components. These preliminary assessments informed the subsequent planning of material characterization through destructive testing. For every structural element, regardless of its construction type, precise dimensional documentation was required, including both cross-sectional measurements and exact planimetric positioning. As evidenced in Figs. 2 and 3, the structural survey meticulously documented both interior and exterior building details. The examination of vertical wall assemblies and horizontal structural elements proved particularly revealing, uncovering traces of historical reinforcement interventions while clearly differentiating between primary load-bearing members and secondary supported elements, such as the distinctive Perret-type brick tile false ceiling system.

The building underwent comprehensive assessment, including both precise geometric surveys and vulnerability analyses. The morphological examination revealed potential plan and elevation irregularities, which were subsequently incorporated into the numerical model. Further investigation of structural components and their connections identified
