Algorithmic modelling processes in scan-to-BIM workflows
No full textThe benefits brought by the application of the BIM philosophy to built heritage are now widely recognised, so much so
that a closely related methodology, Heritage BIM borned. The HBIM finds practical confirmation in the so-called
Scan-to-BIM processes; the data of architectural organisms, in the form of point clouds, are the basis on which the
modelling of information is developed, to arrive at geometric models within which all the information necessary for the
reading and interpretation of the architectural artefact as well as for its preservation and management is collected. In the
paper some of the problems that arise from the application of the Scan-to-BIM processes to complex historical elements
are analysed, particularly related to the phases of creation of three-dimensional models. In addition, a reasoning is made
about how such problems can be solved or at least mitigated, thanks to the use of algorithmic modelling; the aim is to
parameterise the generative process of the models, when the model itself cannot be parametric. In order to do this, a
classic typology of historical architecture was examined: late-gothic vaulted systems

No full textThe essay shows the results of a research aimed at building a digital database of Sardinian military architectures of Second World War. Following an activity of knowledge and cataloguing entrusted to digital survey methods already employed in other case studies, this contribute analyses the IIWW heritage placed in territory of Quartu Sant’Elena, a centre close to Cagliari in the south coast of the island. Many examples of these “sentinels” are positioned along the coastline and the country road and within the actual urban context; these architectures follow the indication of design models indicated by the archival documents using square and circle shape often modified and adapted to achieve a complete mimesis in the landscape that host them. In our case study we found bunkers that seems little churches, houses and water tanks located in a restricted area close to the Simbirizzi lake, in which an integrated (direct, instrumental, and photogrammetric) survey has been carried out
Outside, Around, Inside. New Paths to Discover San Michele Castle (Cagliari, Sardinia)
No full textIn the framework of conservation and enhancement of cultural heritage, accessibility plays a crucial role. Architectural heritage peculiarities call for specific approaches: the same care must be adopted to improve accessibility to historic architecture, designing actions case by case. Starting from these considerations, the contribution is aimed to discuss the accessibility of fortified architecture, a not easily accessible heritage, to make it accessible both in a physical meaning as well as in cognitive, cultural and social. Particularly, the authors propose some reflections about alternative ways of usability for inaccessible architectures due to their typological configuration and as a consequence of previous conservation design. The case study is the medieval castle of San Michele in Cagliari (Sardinia), which was transformed several times during its life and restored at the end of the 20th century. The contribution analyses how a multidisciplinary approach is necessary for the formulation of effective accessibility solutions, especially in complex cases such as fortified architecture. This multidisciplinary approach must be accompanied by the widest possible consideration of the causes limiting accessibility, whether they are physical or related to motor, perceptive or cognitive disabilities

No full textNello studio degli archivi cartacei di architettura, i processi di traduzione digitale dei disegni richie-dono un approccio ermeneutico alla lettura; la modellazione informativa HBIM può rappresentare un utile strumento di supporto, attraverso processi di comprensione e di reverse engineering sul patrimonio costruito. Uno dei prodotti della modellazione HBIM sono le esportazioni di mesh per uso con strumenti esterni.Per la gestione delle informazioni e delle esportazioni, vista la mole e varietà di dati, si è deciso di realizzare un database relazionale strutturato secondo logiche proprie delle scienze archivistiche, estese per l’inclusione di modelli tridimensionali. Il database permette di archiviare le digitalizzazioni dei documenti cartacei, i loro metadati e le nuove riconfigurazioni 3D, oltre a facilitare l’accesso in fase di narrazione delle informazioni.L’uso del database consente la visualizzazione dei modelli e degli elementi di variante tramite un visualizzatore web-based direttamente collegato al database stesso. La scelta delle tecnologie web-ba-sed aperti consente di garantire la massima flessibilità per la gestione e visualizzazione delle informazioni, per calibrarne la consultazione in base alla categoria di utenti
