2. The CHARMING PISTOIA project CHARMING PISTOIA is the acronym of “Cultural HeritAge infoRmation ModellING for PISTOIA: from monitoring data to digital twin”. It is a two-years research project co-founded by the Fondazione Cassa di Risparmio Pistoia e Pescia and the Department of Civil and Environmental Engineering from the University of Florence within the program Giovani@RicercaScientifica. The challenge of CHARMING PISTOIA is to deliver tools and methodologies to improve conservation of historical constructions by ensuring the optimal use of the resources required for the tasks of Control & Preservation. The project is developed by exploiting, as case study, the marble pulpit realized by Giovanni Pisano inside the church of Sant’Andrea in Pistoia (Italy). This emblematic case study provides the opportunity to develop a highly interdisciplinary project by combining, on the one hand, the integration of the informative modelling (HBIM) with structural health monitoring (SHM) data and, on the other hand the definition of robust computational models for static and seismic vulnerability assessment. These activities take up the challenge to investigate on the joint vulnerability assessment between the structures and the works of art contained inside. The research project expects two parts. The first is carried out mainly in-situ and includes the visive inspection of the structure and the acquisition of the experimental data. The second is mainly focused on the model’s design and the selection of proper computer software, from the informative modelling to the computational structural models.

More in detail, four Operational Objectives (OO) mark the project activities (see Fig. 1): • OO1 – State of art and semantic organization

The project starts with the collecting of all the different sources of information available for the Pistoia historical construction analysed, i.e. the Pieve di Sant’Andrea: from the historical evolution of construction and restoration works to the acquired experimental data and monitoring systems related to the structure and the works of art inside, in essence, the pulpit of G. Pisano as a whole. In this first OO, the semantic organization is carried out by defining: (i) the geometric elements which compose the structure and the works of art inside, (ii) the information associated with each geometric element and (iii) the level of accuracy of the geometrical model. Eventually, a detailed literature review is performed in order to assess the state of the art of the present research. • OO2 – Experimental data
