Towards a Semantic Based Hub Platform of Vaulted Systems: Hbim Meets a Geodb

Abstract

In the last years many efforts have been invested in the cultural heritage digitization: surveying, modelling, diagnostic analysis and historic data collection. Nowadays, this effort is finalized in many cases towards the Historical Building Information Modelling. The number of informative models testifying the multifaceted richness and unicity of the architectural heritage and its components is progressively increasing. Information and Model are generally acquired under researches and analysis phases addressed to the preservation and restoration process. Unfortunately, once concluded the research such documentation is mostly left abandoned in the drawers or in the local memory of the computers, and in some cases totally missed. Just a few of them are saved in a server or in the cloud for the duration of the restoration, but without any connection with the maintenance process of historic architectures or knowledge transfer purposes and dissemination. This data loss would lead to the breaking of the cycle of past, present and future, with loss of memory and knowledge. The paper start facing the aspect of managing the information and models acquired on the case of vaulted systems. Information is collected within a semantic based hub platform to perform cross co-relation at a PanEuropean level. Such functionality allows to reconstruct the rich history of the construction techniques and skilled workers across Europe, enriched by 3 case studies surveyed in Prague region. To this purpose a Vault DB has been undertaken with a Vocabulary enriched by the granular information gained from the HBIM models, and with the vault sub-typologies highlighted by a detailed surveying. This paper focuses its attention on vaulted systems. Indeed, vaulted systems are characterized by a variety of solutions developed across time and space, and whose knowledge is generally obtained during researches, or analysis and diagnostic

Extended reality and informative models for the architectural heritage: from scan-to-BIM process to virtual and augmented reality

“… Information sharing: the development of a cloud platform (Brumana et al, 2019;Mazzetti et al, 2015), to share data and informative models, as historical databases, schedules based on the automatic extraction of information previously included in the HBIM modelling and to create an immersive interactive environment (VR and AR) for different types of users (experts, non-experts and tourists) and devices (desktop, mobile, VR headset). Even if the process is not yet automatized, the possibility to have different models and data available within a virtual hub platform will open to the VR/AR/MR developers the possibility to enrich the narratives with validated research and related information.…”

“…Furthermore, the study of the vaulted system was performed to feed the GeoDB vault database, making the data (3D models, CAD drawings…) accessible by anyone at any given time (Brumana et al, 2019;Brumana et al, 2018c).…”

The Integration of HBIM-SIG in the Development of a Virtual Itinerary in a Historical Centre

“…In Italy, due to its large amount of heritage assets and its tradition of safeguarding its monuments, various studies have been performed. At the Politécnico di Milano (POLIMI), the research group led by Raffaella Brumana [12] has extensive experience with HBIM and its integration in GIS for the conservation of parks and gardens. At the Università di Pisa, the research group led by Marco Bevilacqua [13] studied the integration of 3D models in geomatic systems regarding the conservation of cultural heritage.…”

Digital Twin: Research Framework to Support Preventive Conservation Policies

“…The integration of these dimensions in HBIM process appears to be crucial as it addresses two major issues in the field of the heritage documentation. On the one hand, it limits the risks of data obsolescence by integrating all related data into the model for use in conjunction with the operation and maintenance phase of the life cycle of the properties, thus avoiding these data being stored in local databases [21]. On the other hand, it has been argued that the limited interactions among the different spheres of heritage conservation often results in a problematic disconnection between the initial phases of a project, such as the preliminary studies, and the actual interventions in the execution and maintenance phases [5].…”
