NEW PERSPECTIVES FOR MAPPING ALTERATIONS IN HBIM IN CONSERVATION PROJECTS

Historic Building Information Modelling (HBIM) finds one of its most interesting applications in conservation design. The HBIM approach did not originate as a simple data archive method but as an information tool to help the designer at all stages of the building process. Turning to the field of preservation, a lot of information about the building is represented by thematic maps. They make it possible to get a graphic representation of the state of conservation of a facade or to understand the structural situation of a building. This research, experimented on the Arch of Augustus in Aosta, starts from the large amount of data acquired by the RAVA Laboratory of the Superintendence of Aosta over a long period. These data allowed for testing different approaches to thematic mapping, depending on the specific themes to be represented. In any case, even this experimentation required theoretical reasoning that preceded the operational phases. The question, which this article wants only to start to address, concerns the role of thematic mappings in the preservation project carried out with an HBIM approach, their necessity, and their implementation towards truly threedimensional data, which therefore maintains all the information that is directly acquired in three dimensions

HERITAGE 2022 - International Conference on Vernacular Heritage: Culture, People and Sustainability

The study of the hydraulic factories (mills, forges, trip hammers, etc.) of the Valle Sabbia, conducted by a University of Brescia research group, within the "Resilient Valleys" project (funded by the Cariplo Foun-dation), led to the definition of a protocol or guidelines with the ambition of identifying shared and adequate codes of practice to guarantee the correct recovery of this heritage. The object of the survey are artefacts located in functional positions for production activities, today often isolated and not very accessible. The architectural structure and construction features make them particularly vulnerable to deterioration, mo-reso than other types of artefacts. What remains of this building heritage is much closer to the conditions of a ruin which, if recovered or simply maintained, could very effectively convey some of the most charac-teristic features of local economic history. To conserve and maintain this heritage, operational indications and good practice suggestions are proposed, useful in interventions on buildings and hydraulic artefacts. There is neither a compendium with recipes to follow step by step nor even exemplary models, but rather a critical path method that starts from the direct and physical knowledge of the heritage, to arrive at the timely and most suitable conservation intervention. Method suggestions are proposed, which aim to help the owners, users or managers of these architectures, in choosing, within a scenario of traditional and innovative construction techniques available, the most suitable and correct ones to guarantee respect for the buildings’ and hydraulic works’ characteristics, their constructive, morphological, technological, ma-terial peculiarities and, therefore, to monitor and/or solve problems of decay and instability. Ample space is also dedicated to the planned conservation process, in which enhancement will contribute to respecting the material and intellectual integrity of the ruin

THE ARCH OF AUGUSTUS IN AOSTA: DATA AND ANALYSIS REUSE FOR A CONSERVATION PROJECT

The paper proposes a path for the management of the Arch of Augustus in Aosta to exploit the potential of Historic Building Information Modelling (HBIM). The HBIM system acts both as a place where to georeference the available data and as a tool for the elaboration of the conservation project in all its aspects. The system deals with different data from the survey of geometries to that of materials and alterations, up to the conservation project (mainly focused on the surfaces, with the aim of traceability of the events that the monument has lived, lives, and will live). The challenges in this research concern several aspects. First, it will be necessary to adapt the regular geometry of the BIM approach to the complex shapes necessary for the reproduction of surface alterations in the Puddinga stone. In addition, even more important, the ability to manage the monitoring data distributed at different times, comparing and making them available to current and future restorers (and other operators involved in the preservation). These tasks will be fixed by drawing up a dynamic conservation project, i.e. one that can make use of the available data at any time and all those that will become available during the work. Attempts of data digitization to give a shared value to the conservation activities had already been proposed in the past. The new research now starts from the reconnaissance of the weaknesses of the previous proposals, mainly related to the use of tailor-made systems (software) that are difficult to maintain, to implement and use in a very heterogeneous team of operators (architects, archaeologists, engineers, topographers, chemists, historians…

Imparare dalla tradizione. Tecniche costruttive e pratiche di riparazione dell'edilizia storica nel territorio bresciano: alcuni esempi

In the field of conservation, the issue of protection of traditional architecture - which includes historical rural buildings – is still neglected, even though, since the 1970s, a great number of studies on construction techniques and functions of rural architecture have been published. These studies show how the wisdom of traditional construction techniques (the use of local building materials, techniques characterized by minimum intervention, compatibility, reversibility), in many case could guide present practices of conservation.The essay focuses on the area of Brescia where, in spite of significant transformations over time of buildings and territory, many examples of traditional architecture still exist. The aim of the paper is also to suggest, by presenting some case studies, a strategy for conservation which proposes a dialogue between traditional methods, technological innovations and economic sustainability of interventions.Keywords: Traditional architecture, Brescia, Sustainability, Construction techniques, ProtectionNell’ambito del restauro, il tema della conservazione dell’architettura tradizionale - ove includiamo in particolare gli edifici storici legati alla produzione agricola e, più in generale al mondo contadino - è a tutt’oggi trascurato. Ciò nonostante l’interesse, già a partire dagli anni settanta dello scorso secolo, per i modi di costruzione e d’uso di queste architetture che testimoniano modi di vita ormai superati e per questo oggetto di grande interesse. Questi studi, hanno peraltro dimostrato come la saggezza del costruire tradizionale (l’impiego di materiali facilmente reperibili in loco, l’adozione di tecniche improntate, spesso per questioni economiche, al minimo intervento, alla compatibilità, alla reversibilità) potrebbe in molti casi ispirare le odierne pratiche di riparazione.Il contributo indaga un territorio, quello della Lombardia orientale, che nonostante il massiccio rinnovamento edilizio conserva ancora numerosi esempi di architetture tradizionali e suggerisce – presentando alcune esperienze concrete - una strategia per la conservazione di questo patrimonio che proprio dalla tradizione trae ispirazione proponendo un dialogo aperto con il tema dell’innovazione tecnologica e della sostenibilità economica degli interventi.parole chiave: Architettura tradizionale, Brescia, Sostenibilità, Tecniche costruttive, Conservazion

Il ruolo dell’amministrazione locale nella rigenerazione dei centri storici: il caso di Gardone Val Trompia (Brescia)

The municipality of Gardone Val Trompia (Province of Brescia) has always played an important role in the area of Brescia. Economic stability, which it has enjoyed for decades, has been put in crisis by progressive changes in the local economy's driving sectors. The latter have left their mark, not only on the productive settlements but also on the other vulnerable parts of the settlement system. Since the 1990s, the oldest building fabric has been in the process of abandonment  that continues to this day. This process has led to a progressive impoverishment of the social and economic system, accompanied by the effects of neglect of manufactured buildings. After some unsuccessful attempts by the municipal administration to urge people to live in the historical centre, the University of Brescia has been consulted to seek a contribution to reverse the direction. In the essay, we intend to refer to the path taken and the strategies implemented. Il ruolo dell’amministrazione locale nella rigenerazione dei centri storici: il caso di Gardone Val Trompia (Brescia)Il comune di Gardone Val Trompia (Provincia di Brescia) ha sempre svolto un ruolo importante di riferimentonel territorio bresciano. La stabilità economica, di cui ha goduto per decenni, è stata messa in crisi da progressivi cambiamenti, nei settori trainanti dell’economia locale. Questi ultimi hanno lasciato segni, non solo sugli insediamenti produttivi, ma anche sulle altre parti vulnerabili del sistema insediativo. A partire dagli anni 1990, il tessuto edilizio più antico stanno vivendo un processo di abbandono che perdura ancora oggi. Questo processo ha determinato un progressivo impoverimento del sistema sociale ed economico, al quale si sono accompagnati gli effetti dell’incuria dei manufatti edilizi. Dopo alcuni tentativi falliti dell’Amministrazione comunale di sollecitare le persone a vivere in centro storico è stata conivolta l’Università di Brescia per cercare un contributo per invertire la direzione. Nel saggio si intende riferire il percorso attivato e le strategie messe in atto. Il comune di Gardone Val Trompia (Provincia di Brescia) ha sempre svolto un ruolo importante di riferimentonel territorio bresciano.

Il cantiere di conservazione: quali contributi nella ricerca disciplinare?

The paper aims to deepen the close relationship that exists between professional activity and research in conservation projects and sites. These two dimensions of the profession of the architect are tightly tied and necessary the one to the other. Collaboration on the daily problems of design and construction and the resources offered by research institutes is an exemplary synergy of mutual development, which promotes updating and enhances the quality of the two sectors. This makes the link between the University and the professional world less incisive and constructive. For the discipline of conservation this is a problem not only to the detriment of recent graduates, but to the detriment of the protected good. Thanks to the successful consultation with workers in the conservation sector, some students were involved in the visit of construction sites. The validity of the direct experiences offered was highlighted and as moments of confrontation with entrepreneurs and professionals they represent a good practice to be supported

La sfida delle Valli Resilienti: una visione comunitaria per il domani

The theme concerning the restoration of urban texture built in historical centres, boosted through the reinterpretation of the “Carta di Gubbio”, has been enriched in the last decades of considerations about the role of such inhabited centres, especially in the case of minor centres, that have to be be taken into consideration in respect with their own territory and the main centres. Henceforth, intervention strategies have been derived with which the theme of recovery of buildings is entwined alongside the territory project. Beside the SNAI (2014), other financing project related to specific areas – among which the AttivAree (Fondazione Cariplo, 2016-2020) cross-sectorial program, have fostered a multidisciplinary, place-based approach which finds its core in a territorial scale project. The specific case of the Valli Resilienti project, as part of AttivAree, offers several ideas so as to discuss about strategies which, instead of focusing on structural interventions in driving financial sectors, try to trigger an improvement on a day-by-day basis, based on the knowledge of the areas and their potential and on the recovery of the existing heritage, albeit searching for solutions that may combine the traditional technical knowledge with state of the art technologies. In this perspective, a renewed attention is triggered in order for it to be put to the test on new challenges related to the recovery of the building stock of the historical fabrics
