Abstract
For few academic years, in the courses of Architectural Restoration of the Department of Science of Civil Engineering and Architecture of the Bari Polytechnic we are carrying out activities of non-destructive diagnostic related to the field of archaeological prospection and analysis of the conditions of decay of the historical architectural surfaces.
The paper intends highlight how the learning experience has allowed to understand the conservation status directly on the field of investigation. This knowledge, acquired in the learning experience, lets to refine the ability to program a diagnostic analysis process congruent with the visible degradation aimed at achieving better understanding of the building conditions, and guide the conservation project.
The application experiences are mainly related to the following types of activities:
1) archaeological prospecting
2) analysis of the decay of masonries (ancient and modern)
3) analysis of the degradation conditions of architectonical and artistic surfaces (ancient and modern)
The teaching model, in the first instance, had to bring out the big difference between the non-destructive diagnostic systems and the "minimally destructive" ones. the "minimally destructive" ones are specifically linked to the structural and seismic analysis, necessarily "numerically correct" and aimed to the quantitative definition of the physical parameters investigated.
The "indirect" analysis (qualitative) we are carrying out in our laboratories, through the measure of physical quantities not directly related to the strength characteristics (but still related through statistical algorithms), allows to give an assessment of the condition of the artefacts observed without any damage, even minimal. However this analysis allows characterizing the modifications of the behaviour of structures in the time, their decay conditions and the variation of the material density.
The most interesting result comes from the overlapping of different methodologies that can combine different levels of criticism giving each one the results to the issue posed from the other.
The involvement of the students in this process allows to focus on the difficult relationship between the design of diagnostic testing and the expected result at the end of the campaign, as well as focus on the issue of define an appropriate diagnostic project to obtain a coherent result for the conservation project.
It may allow a more articulated reading of the artefact that highlights the complexities of situations often linked to the presence of more degradation factors. This is an extremely common condition in the field of architectural restoration and on which are centred the main troubles of professional activity on our field.
