La diagnostica per il progetto o il progetto per la diagnostica?

Starting from 2012, the Department of Sciences of the Civil Engineering and the Architecture of the Polytechnic of Bari, through to the MIUR-FIRB project, has been equipped with geophysical instruments with the specific purpose of being able to carry out some preliminary archaeological research of the excavation and analysis of the state of conservation of the ancient masonry for their restoration. The experience gained in the years 2012 - 2015 within the FIRB project has allowed the same analysis models to be developed on different fronts, in fact, in the methodologies of execution of the survey, the analysis of the built masonry of historic buildings as well as the sub-foundation grounds is not dissimilar to the application experimented in the archaeological field, however the study data, for the built factories, characterized by functionality and static needs, needs a much more accurate interpretative development. The contribution, after a brief methodological introduction want to describe the geophysical techniques of indirect investigation (Geophysics and Acoustics), intends to highlight the complexity of the diagnostic campaign project that must be planned with the awareness of the nature of the investigated object, of the potential of the tool and of the cognitive questions. There are to presented two case studies in which the data emerging from the indirect analysis allowed a correct interpretation due to a correct setting of the survey method thanks to the prior knowledge of the asset. In both cases, the alignment of the figures of the Restoration Architect and of the Geophysicist, starting from the planning phase of the survey, has made it possible to optimize the cognitive results by making the best use of the available technologies.
