<p><strong>Abstract.</strong> Informative models are not limited only to new construction or existing building but can also be used (also been used) for large infrastructure management like bridges. The adoption of informative content models for structural health monitoring (SHM) of such infrastructures poses some issues that need to be solved in order to develop smooth management and maintenance workflows. This paper describes a novel methodology for the generation of a detailed BIM of a complex medieval bridge and the possibility to link specific data coming from load testing. Integration of information coming from different data sources is one of the most important aspects for the development of maintenance programs. However, each actor in the process makes use of different strategies and protocols whose integration can generate bottlenecks. To partially overcome this limitation a cloud-based solution was used, and a Building Information Model (BIM) of the bridge was used as main collector of information for the different stakeholders involved in its management.</p>

Recent developments in Building Information Modelling (BIM) technologies are facilitating the management of historic complex structures using new applications. This paper proposes a generative method combining the morphological and typological aspects of the historic buildings (H-BIM), with a set of monitoring information. This combination of 3D digital survey, parametric modelling and monitoring datasets allows for the development of a system for archiving and visualizing structural health monitoring (SHM) data (Fig. 1). The availability of a BIM database allows one to integrate a different kind of data stored in different ways (e.g. reports, tables, graphs, etc.) with a representation directly connected to the 3D model of the structure with appropriate levels of detail (LoD). Data can be interactively accessed by selecting specific objects of the BIM, i.e. connecting the 3D position of the sensors installed with additional digital documentation. Such innovative BIM objects, which form a new BIM family for SHM, can be then reused in other projects, facilitating data archiving and exploitation of data acquired and processed. The application of advanced modeling techniques allows for the reduction of time and costs of the generation process, and support cooperation between different disciplines using a central workspace. However, it also reveals new challenges for parametric software and exchange formats. The case study presented is the medieval bridge Azzone Visconti in Lecco (Italy), in which multi-temporal vertical movements during load testing were integrated into H-BIM.

La tesi è articolata in quattro capitoli. Nel primo si è ripercorso lo status questionis e la fortuna critica del Maestro del "Pantheon" e della sua bottega: tale artista, infatti, è noto agli studi già da un secolo. Si sono pertanto enumerati i diversi interventi degli studiosi, soffermandosi sui principali, esponendoli criticarmene e provvedendo a sfrondare le ipotesi oggigiorno meno praticabili. Nel secondo capitolo si è data voce ad un’analisi del codice Lat. 4895 (Parigi, Bibliothèque nationale de France), mostrando le specificità sia del miniatore bolognese, attivo nei primi fogli, sia del Maestro del "Pantheon", attivo nella restante parte delle carte. Nel terzo capitolo si sono analizzati i codici attribuibili alla bottega del Maestro del "Pantheon", collocati cronologicamente nel quarto decennio del XIV secolo, nonché sono stati presi in considerazione i volumi commissionati da Bruzio Visconti, il quale fu prolifico mecenate di manoscritti miniati tra quarto e quinto decennio del XIV secolo. Nel quarto capitolo, infine, si sono voluti mostrare i collegamenti fra il Maestro del "Pantheon" e la cultura figurativa lombarda della prima metà del secolo; facendo anche emergere la figura di Giovami Visconti, arcivescovo di Milano, quale committente e possessore di codici.
The thesis is divided into four chapters. The first traces the status questionis and the critical fortune of the Master of the "Pantheon" and of his workshop: this artist, in fact, has been known for a century. Therefore, the various interventions of the scholars have been enumerated, focusing on the main ones, exposing them, criticize them and removing the hypotheses that are less probable today. In the second chapter, was provided an analysis of the ms. Lat. 4895 (Paris, Bibliothèque nationale de France), showing the specific characteristics firstly of the Bolognese illuminator, active in the first leaves, and secondly of the Master of the "Pantheon", active in the remaining leaves. The third chapter analyzes the codes attributable to the workshop of the Master of the "Pantheon", placed chronologically in the fourth decade of the fourteenth century, as well as the volumes commissioned by Bruzio Visconti, who was a prolific patron of illuminated manuscripts between the fourth and fifth decade of the fourteenth century. Finally, in the fourth chapter, is showed the connections between the Master of the "Pantheon" and the Lombard figurative culture of the first half of the century; also bringing out the figure of Giovami Visconti, archbishop of Milan, as patron and owner of manuscripts.
