Diagnostics archive data for the analysis of the Architectural Heritage’s conservation state

Placed as a hinge between analysis and decision making, the diagnosis implies interpretations on whose correctness may depend the effectiveness of restorations and the building’s future life. In the diagnosis’ context, an important role is played by the knowledge of the restoration interventions’ history and investigations in order to orient new diagnostic investigations and to compare data acquired at different times with the aim to integrating them and discovering constructive and structural variations occurred. This integrated methodology aspires to multiple objectives including the design of a new investigation plan made reliable and effective through ‘archival diagnostics’. In this sense, archival research stands as a means of adding information on the conservation history and degradation, representing a useful diagnostic tool. Hence the intention to begin a reasoning on the added value that the anamnesis and diagnosis based on archive data can provide from a cognitive and design point of view.
