Abstract

The application of digital survey practices on Built Heritage has to face in different cases with singular typologies of architectural systems that have an out-of-scale proportion (as tower bells, minarets, civil towers), facing also with uncommon phenomena of structural instability and decay, due to their specific geometry. Their study shows intrinsic instability systems related to their singular structural form, the unusual dimension and the low frequency of ordinary maintenance and restoration, which tend to increase throughout the lifecycle of the building and the exposition to agents of its construction materials. In this cases, the aim to monitor the conditions of conservation influences the methodological purposes and pipeline of survey, bridging the practices of rangebased and image-based survey through new standards of density, resolution and reliability of data necessary to assess the analysis of such type of monuments. A reflection on the quality of morphological databases to derive digital elaborations and maps for the analysis of instabilities and the monitoring of risks in out-of-scale buildings is presented.
