The documentation of the architectural heritage requires the storage of large amounts of information that must be stored and processed in very different formats, since it comes from experts from different areas of knowledge. This heterogeneity of information makes communication difficult among professionals who participate in documentation work, such as restorers, architects, engineers, archaeologists or historians, with the transfer of information being one of the biggest problems to be solved, through the creation of a methodology that favors the diffusion and accessibility to the materials coming from the investigation. The aim of the study is to create a protocol or methodology, to create a graphic database that allows the inventory of the architectural heritage in Aragon. The solution implies the development of a geometric model that allows to include and relate information related to it. The format is a HBIM model capable of incorporating information on a stratified support, with visualization, documentation and management capabilities that allow a complete view of the building to be cataloged, incorporating useful information for its conservation, restoration, protection and dissemination, as well as interoperability between tools and other systems throughout the entire life cycle of the object. In this research, we will work with the virtual platform Petrobim, a tool composed of a database and a viewer, whose purpose is the management and query of information linked to a 3D model, throughout the entire cycle building life.

Cultural Heritage has been significantly impacted by advancements in the Information and Communications Technology domains, which have inspired a strong multidisciplinary interest and enabled the development of innovative strategies for the preservation, management, and enhancement of the heritage itself. Notably, the digitisation process, which entails the acquisition of 3D data obtained through cutting-edge LiDAR and photogrammetric scanning techniques, is set up as an advantageous tool for producing an accurate representation of the historical buildings. In addition, point clouds and reliable HBIM models have caught the minds of the architectural community, and are now receiving huge backing from Artificial Intelligence. Such support is provided by procedures that link semantic features to structural and decorative elements. In this scenario, the following research is presented: the aim is to test an automated iterative process within a scan-to-BIM methodology, starting from automatic point cloud segmentation operations with open-source, model-fitting algorithms. This method will prove to be a solid support for the final phase of the 3D parametric/adaptive reconstruction that’s also compatible with BIM Authoring. The study focuses on various masonry vaulted systems. These types of structures are first examined using ideal models, which were perfectly discretised and set up by the user, and then employed as a starting point for validating the parameters of the RANSAC algorithm on point clouds acquired by laser scanners. These latter ones nevertheless have irregular geometries, making comprehension, analysis, and management far more challenging.

In the current landscape dominated by Artificial Intelligence, the integration of Machine Learning and Deep Learning within the realm of Cultural Heritage, particularly within architectural contexts, is paramount for the efficient processing and interpretation of point clouds. These advanced methods facilitate automated segmentation and classification, significantly improving both the clarity and practical use of data acquired from laser scanning and photogrammetry. The present study investigates the Palacio de Sástago—a prominent Renaissance palace in Zaragoza, Spain—and introduces a cutting-edge modus operandi for the automated recognition of architectural elements within the palace’s inner courtyard. Employing the well-established Random Forest algorithm, implemented in a Python environment, the framework begins with a comprehensive evaluation of the geometric features identified in the LiDAR point cloud. This process employs the Mean Decrease in Impurity metric to evaluate the relevance of each variable. To boost the accuracy and efficiency of the final classifications, the features are refined post-assessment, enhancing both the training phase and the algorithm’s later evaluation. The research’s findings demonstrate significant potential, supporting advancements in CAD systems and HBIM that will enable more precise, automated modelling of architectural elements, thereby enhancing the accuracy of digital reconstructions and improving conservation planning for heritage sites.

La vivienda social construida en España entre 1939 y 1976 supone un patrón urbano extendido en la ciudad contemporánea. Sus condiciones de partida y el efecto del tiempo la han llevado a desarrollar una serie de obsolescencias, que hacen necesario intervenir para conseguir su revitalización. Los programas desarrollados en los últimos años se ocupan de dotar a las edificaciones de unos niveles de habitabilidad adecuados, pero también de su articulación como grupo, y de su integración en la distribución socioeconómica del núcleo urbano. Mediante el análisis de la Remodelación Urbana de Orcasitas (Madrid) y de las Viviendas del Gobernador (Barcelona), la Transformación Urbana de La Mina (Barcelona) y la Rehabilitación Integral del Barrio de Lourdes (Tudela) se estudiará la evolución de estos modelos de actuación.

With current data acquisition techniques, exhaustive documentation of patrimonial goods is generated, which allows obtaining a 3D geometric model, on which data from research from research is generated. As in other fields of architecture, the latest graphic techniques and manipulation of the image, allow a working methodology other than the current one in the patrimonial field. The information systems have been evolving towards technologies developed with open source software, the use of standards, ontologies and the structuring of information and of the 3D model itself under a semantic hierarchy. Interoperability between databases is favored and the maintenance of applications is ensured. The purpose is to support decision-making related to the model and simultaneously, serve multiple purposes such as cataloging, protection, restoration, conservation, maintenance or dissemination, among others. The research carried out for the realization of the survey of the City Council and Lonja of Alcañiz (Teruel), has the aim of expanding the historical knowledge of the buildings and delimiting its possible constructive phases, in order to obtain the geometric reality of the buildings. In this way, provide greater instruments to carry out the drafting work of the set restoration project.

La documentación del Patrimonio requiere una representación ordenada de la información almacenada, debido a la diversidad de disciplinas que intervienen en el sector, con campos altamente especializados, que afecta a la comunicación entre los diferentes agentes que intervienen en los procesos de documentación. La recopilación, clasificación, análisis y presentación de la información precisa del empleo de protocolos para ordenar y utilizar de forma comprensible y coherente. Por ello, la propuesta metodológica plantea la definición de unas pautas generales para realizar la captura y el procesado de la información generada, con el fin de desarrollar una base de datos gráfica que permita representar a través de un modelo 3D la información relativa al patrimonio arquitectónico. La documentación, organizada bajo un modelo de datos común, facilita la interoperabilidad y la accesibilidad a la información archivada, y su posterior gestión.
