Analysis of a building (whether historic or modern) in order to identify the construction techniques and/or the state of preservation/degradation of the materials through the use and integration of non-destructive techniques such as: infrared thermography, to survey the superficial temperature values and highlight any issues (e.g., thermal dissipation, humidity in the masonry, irregularity of the materials, superficial damage); endoscopy and videoscopy, to inspect parts that are not visible by means of small openings, whether existing or made during the investigation; UV photography, to identify surface organic material and its distribution through illumination with UW lamps, which is of particular importance in the case of decorated surfaces; cover meters, to identify the presence, direction and diameter of metal elements within the structure.
