Abstract

Since the introduction of expert systems for the preservation of Cultural Heritage, several research projects have developed codified procedures for the condition assessment of the materials composing historical buildings. The data stored by recording the decay typologies observed on the materials was considered a first step for supporting future interventions on the historical surfaces of the buildings. This kind of formal tool, providing data collected over the course of time by periodical survey campaigns, showed also other potentialities, like damage prediction and risk assessment. In recent years, the Veneranda Fabbrica del Duomo, the board managing the Cathedral of Milan, developed new approaches for preventing the risks connected to its rich apparatus of stone decorations. Based on the wide experience matured in a long-lasting calibration of good practices set for preserving the architectural features of the temple, the Veneranda Fabbrica adopted recently a new analytical procedure for detecting risk conditions aiming at evaluating the evolution of decays and their potential consequences. The proposed method was studied by the authors, within the convention between Veneranda Fabbrica and Politecnico, in order to verify its reliability through several simulations of different scenarios. Moreover, this study pointed up the difficulties concerning an objective evaluation of the parameters on which the analytical procedure is based and therefore the need of defining criteria for an effective and reliable data gathering and processing to support decision-making. The expected results should provide alarm in case of dangerous scenarios and recommendations concerning the planning of preservation actions: the updating of the inspection interval, the necessity of further diagnostic investigations and the urgency of repair interventions.
