In the management process of the architectural restoration site, we are witnessing the adoption of processes conducted largely in the traditional way increasingly alongside activities strongly influenced by new technologies. In particular, the new instruments for the metric survey return more and more information at very high resolution, progressively reducing the acquisition time. In recent years, In order to manage and structure these data, the disciplines of Representation and Geomatics have developed increasingly efficient restitution workflows by applying Building Information Modeling (BIM) processes to the built heritage (HBIM).  While the acquisition tools have evolved rapidly, the same cannot be said for the methodologies for managing the collected data and the tools for informed models. At the regard, there is a growing need to apply Machine Learning processes to improve data management and modelling in heritage restitution processes. 

The paper briefly presents the semi-automatic DECAI workflow for mapping architectural surfaces and their annotation in the HBIM environment. The case study is the elevation on Via Porta Praetoria, the facades of the hallway and the facades of the internal cavity of Palazzo Ansermin, in Aosta. The paper does not presume to replace the traditional survey procedures but rather to propose an integration and optimization, following a workflow that starts with a photogrammetric survey and ends with the informative enrichment of an HBIM model of the building.

The research, promoted by the DAda-LAB Laboratory of the University of Pavia, aims to structure a methodology and an operational protocol for the documentation of water canals in the Pavia territory. This protocol appears necessary to optimize the various phases that characterize both the documentation activities and the three-dimensional graphic representation of the agricultural territories of the flat land and their canalization networks through information systems.

The study evaluates the most functional procedures to respect a infographics conformity in the building of reliable 3D models. 

The investigation activities see the construction of digital atlases on the elements that constitute the landscape.

The result aims to product an informatic system to promote territory knowledge. This product qualifies as a documentary corpus made up of models, census data, and more generally of information systems connected to point clouds and 3D surveys. The result allows obtaining technical information, functional to administrations and consortia to simplify and improve the management of the territory, with economic and productive advantages.

This paper reports the first results concerning the experimentation of information management of HBIM artefacts owned by municipalities, as a result of a research path aimed at determining methodologies and protocols for the representation of these classes of assets, with the aim of simulating future interactions with designers in correspondence with future public tenders.

The research presents an experimental approach for the damage documentation of existing structures. The main aim is to identify a methodology from the integrated digital survey (range- and image-base) to BIM to synthesise quantitative information on the existing damage that can be exported for the structural assessments.

The research aims to integrate the Index of Masonry Quality into a Heritage BIM workflow, with the support of Visual Programming Language (VPL). The study is part of a broader set of  investigation methods for the digitisation of built heritage for facilitating the management and accessibility of information. By reducing analyses’ costs and time, it is suitable for urban scale evaluation of vernacular historic centres.

The HBIM methodology applied to a historical asset is an extremely interesting topic for the study of Italian heritage. In order to reach a good level of information about the fortress, several steps have been performed using IT and web tools. Thanks to the historiographical analysis we have been able to hypothesize a probable date of origin, while surveys with laser scanners, drones and photography – for the identification of decay form – were indispensable for architectural modeling. Appreciable results were obtained both with the representation of the model and with its informative reliability, implementing the digital twin through the design of recovery interventions and the management of times and costs.

The present work constitutes a significant and innovative step in the testing of solutions for the interaction with digital facsimiles, in particular it investigates the potential of Mixed reality applications for the communication of three-dimensional modelling projects. In this case, the 3D reconstruction of the Rocca-Torrione complex by F. di Giorgio Martini in Cagli is the exemplar case study on which is possible to test the principles of the reference charts in the field of Digital Cultural Heritage (DCH) but also to reflect on methodologies of storytelling for the tangible and intangible heritage. Furthermore, these studies, together with the local and regional networks, represent the precondition for the creation of a Study Centre on Francesco di Giorgio Martini which will be based in Cagli.

This paper presents the results of a research aimed at demonstrating the potentialities and cur-rent limits of some BIM-based approaches in the field of Facility Management. Today the man-agement and interpretation of large amounts of data of different nature and disciplinary scope is one of the most relevant problems in the definition of new and more efficient information manage-ment processes in the construction sector. 

Two different processes are compared for the acquisition and management of the parameters needed for the asset management phases of existing school buildings. The first method involves the compilation of schedules within the BIM authoring software by means of an appropriate mapping of the parameters with reference to the information exchange scheme established by COBie (Construction-Operations Building Information exchange); the second method uses a spe-cific software for FM, dRofus, which is able to create a direct link with the BIM authoring software for the bi-lateral writing of the parameters. Through a comparative analysis, the results of the case study G. Rodari Primary and Infant School in Florence are discussed.
