Abstract
Abstract. Great attention is increasingly paid to the heritage belonging to the XX century, particularly for the spatial structures made of concrete, that are a significant trait of this modern movement architecture. Since they demand today urgent conservation plans sustaining their deterioration, the multidisciplinary researches should devotes a profound investigations for tailored approaches providing a clear indication of best practices and recommendation for correct 3D documentation, information management and structural assessment and monitoring. In this framework, the Geomatics approaches are advancing the interests toward the multi-scale and multi-sensor digitization and for supporting management of complex information in enriched 3D models. The iconic halls B and C in Torino Esposizioni (Italy), designed by Pier Luigi Nervi, is the case study presented. It was recently awarded by the Getty Keeping it Modern grant. The multi-disciplinary research conducted, still in progress, focuses a particularly into the investigation of the structural analysis and consistency of ferrocement elements of the vaulted system finalized to the structural condition assessment. Here the role of multi-scale and multi-sensor 3D models is investigated, such as the development of a digital twin of the halls as a starting point to create an enriched informative system. The reconstruction of this model particularly considering the large extension and the complexity of the spaces, is addressed to works as a collector of 3D multi-sensor data and information related to the diagnostic investigation on structural health monitoring for the durability of ferrocement elements.
Highlights
In the broad panorama of techniques used for the digitisation of architectural and cultural heritage, a leading role is certainly played by studies and projects aiming at the use of 3D sensing methods to support structural investigations with the purpose of identifying the structural characteristics of historical buildings and determining the state of health of structures pertaining CH
Another very important issue concerns the massive availability of 3D modeling derived from heritage digitisation projects that are offered to future generations who will be engaged in conservation projects
The integrated approach proposed in this research starts from the assumption that the 3D multi-scale and multi sensor model plays a crucial role in the multiple investigations on the structural assessment of this complex ferrocements architecture of XX century, and its effectiveness is supporting structural analysis based on the achievement of the following goals, in inverse order here reported
Summary
In the broad panorama of techniques used for the digitisation of architectural and cultural heritage, a leading role is certainly played by studies and projects aiming at the use of 3D sensing methods to support structural investigations with the purpose of identifying the structural characteristics of historical buildings and determining the state of health of structures pertaining CH. A fundamental concept – developed with an increasing number of proposals and solutions analyses – is that the use of the HBIM strategies is and no longer so much oriented to solve the issues related to the 3D modeling of complex CH objects This approach considers HBIM as an environment in which managing the many heterogeneous information characterizing architectural assets in connection with geometric information (Turrina & Attico, 2021). An EU project called VIGIE is operating, aimed at
