## 5 Conclusions  
The paper highlights an essential aspect of cultural heritage management, combining scientific methodologies and traditional practices of inspection and assessment of the condition of a heritage building, located in a seismic zone. The research concerns the processes and methods used to identify the current condition of the building, which includes the structural aspect and the materials used. These techniques are used to develop solutions to strengthen and stabilize the structure weakened due to age, environmental factors or previous interventions. Comprehensive documentation of the heritage building before, during, and after consolidation work is essential. This includes photographic records, condition reports, and analytical data, providing a thorough record and guiding future conservation efforts. Advanced technologies, including non-invasive analytical techniques, like XRD, SEM-EDX, TGA-DTA and 3D modeling, are increasingly used to assess and monitor the condition of heritage building, aiding in consolidation efforts. The LiDAR technology used gave data to develop quick acurate 3D models, allowing the identification of actual state for structural skeleton and materials. The composition of the original materials in the masonry structure of the building was identified by X-ray diffraction (XRD), scanning electron microscopy (SEM-EDX) and differential thermal analysis (TGA-DTA). XRD was used to determine the mineralogical composition of materials, and in the analysis of masonry, it identified crystalline phases in mortar and aggregates, such as calcite, quartz or clay minerals, thus revealing the composition of the binder. Scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX) provided high-resolution images of the surface morphology of the samples and elemental composition. SEM captures detailed images, while EDX identifies the elements present and analyses the microstructure of mortar and aggregates, highlighting the size, distribution and bonding of particles, as well as any changes over time. Differential thermal analysis (TGA-DTA) identified the thermal stability of mortar components, helping to understand phase transitions and the composition of organic and inorganic materials. The identification of a moderately hydraulic, calcite-based mortar indicates that the binder has some ability to harden underwater, which is significant for understanding the engineering properties and durability of the structure. The presence of siliceous aggregates suggests that the mortar was designed for specific physical properties, possibly reflecting regional availability of materials or techniques. The results of the research can provide insights into the period of construction by comparing the characteristics of the materials with known historical data, helping restorers to establish a timeline for the evolution of the building. Knowledge of the original materials allows restorers to choose compatible materials for intervention works, reducing the risk of further degradation, and the heritage building retains its authenticity and cultural significance. It also helps them to identify previous repair works, which may have used different materials or methods, important aspects for the conservation strategy. Overall, these advanced research techniques not only help to accurately characterize the materials used in the historic masonry structure, Costache Conachi Manor, but also play a vital role in developing knowledge of restoration and conservation practices.
