ABSTRACTSurviving historic train sheds constitute a broad and representative sample of metal construction of the period 1850 to 1930 in France.

First, the specificities of this architectural heritage are highlighted and compared with other countries and other types of construction. Then, based on extensive archive material held by the French national railway company SNCF, the modifications the metallic structures underwent as restoration projects were carried out are analysed. It appears that the restoration practices significantly evolved between the 1970s-1980s and the beginning of the 21st century, becoming more sensitive to heritage preservation.

ABSTRACTThis paper describes the implementation of an open-source platform integrating HBIM-IoT monitoring sensors, applied to the Royal Site of Carditello, a Bourbon 18th-century Palace near the city of Capua (Italy). Based on open standards and processes, the platform is accessible on different devices through the Internet and acts as a digital representation of the building and the monitoring system therein, allowing users to navigate a detailed HBIM model and query, visualise and manipulate static and dynamic information attributed to the building and its collections, as well as the data from applied sensors, linked to their virtual objects’ equivalent in the model. Integrating robust data management with a user-friendly 3D interface, this solution aims to enhance the preventive conservation of historical buildings and their collections, which depend on regular monitoring and a systematic diagnostic programme over time.KEYWORDS: Built heritageconservationdigitalisationHBIMhistorical architectureIoTmonitoringopen sourcesensors AcknowledgmentsThe application of the workflow to the Royal Site of Carditello is part of the “Innovation for Data Elaboration in Heritage Areas IDEHA”, project code ARS01_00421, co-financed by the PON Research and Innovation 2014–2020, Directorial decree no. 1735 of 13 July 2017 of the Italian Ministry of Education, University and Research (MIUR), whose main aim is to create and open an IT platform for Cultural Heritage by combining digital content from traditional repositories with real-time information generated by users or environmental sensors.The authors are grateful to Antonio Spagnuolo and Energreenup s.r.l. to make available the sensors’ data of the RE-SEMIRTO project, financed by POR CAMPANIA FESR 2014 – 2020, with the participation of the “Real Sito di Carditello Foundation” and the University of Campania “Luigi Vanvitelli”.The authors are also grateful to Microgeo s.r.l. to support the laser scanner data acquisition; to Michele Calvano, Stefano Cursi, Rana Daneshvar Salehi, Leo Lorenzi, Leonardo Cinardi, Chiara Nugara, Serafina Cariglino, Heba Daraghma, for contributing to the HBIM model of the Royal Site of Carditello.Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported by the Ministry of University and Research (MUR) of Italy - project “Innovation for Data Elaboration in Heritage Areas IDEHA” - code ARS01_00421 [PON Research and Innovation 2014-2020, Directorial decree no. 1735 of 13 July 2017].

ABSTRACTWith the advancement of graphic engines, real-life structures can be digitized with more realistic representations than before. Virtual models obtained from LiDAR (Light Detection and Ranging) data in real-time applications can be inspected in graphic engines without rendering a point cloud. Well-known proprietary software is used to convert scanning from LiDAR into meshes of triangles that work the best on graphic pipelines. However proprietary software is usually expensive, hard to learn, and requires manual interaction. The proposed methodology generates virtual models from LiDAR with little manual interaction employing open-source software in an automated workflow for generic conversion. The point cloud is registered for geo-reference, processed for building textured models, and implemented in Unreal Engine 5 for Virtual Reality deployment. Specific improvements were made to the selected study case of the Castro of Santa Trega. Visualization of the model is overall more realistic than the rendering of every point in a cloud. The average framerate is improved upon a 229% when rendering optimized meshes compared to point clouds, leading to an enriched visualization quality and reduced data size. A Virtual Reality (VR) experience was implemented with an average of 143 FPS, surpassing the standard 90 FPS recommended to avoid motion sickness.KEYWORDS: Computer graphicscomputer visionheritagelidarpoint cloud processing AcknowledgmentsThis research has received funding from Xunta de Galicia through human resources grant (ED481D-2023-005) and competitive reference group (ED431C 2020/01) and from the Government of Spain through project “Software multi-capa para el procesamiento online de datos lidar enfocado a la monitorización del transporte” with reference PDC2022-133851-I00 funded by MCIN/AEI/10.13039/501100011033, and from the European Union’s “NextGenerationEU”/PRTR”.

摘要随着图形引擎的进步,现实生活中的结构可以数字化,具有比以前更真实的表现形式。在实时应用中,从激光雷达(光探测和测距)数据中获得的虚拟模型可以在图形引擎中进行检查,而无需渲染点云。著名的专有软件用于将激光雷达扫描转换为三角形网格,在图形管道上工作得最好。然而,专有软件通常价格昂贵,难以学习,并且需要人工交互。所提出的方法从激光雷达生成虚拟模型,在自动化的通用转换工作流中使用开源软件进行很少的人工交互。点云注册用于地理参考,处理用于构建纹理模型,并在虚幻引擎5中实现用于虚拟现实部署。对选定的Santa Trega Castro研究案例进行了具体的改进。模型的可视化总体上比渲染云中的每个点更真实。与点云相比,在渲染优化网格时,平均帧率提高了229%,从而提高了可视化质量并减少了数据大小。虚拟现实(VR)体验的平均每秒143帧,超过了为避免晕动病而推荐的每秒90帧的标准。关键词:本研究获得了Xunta de Galicia的人力资源资助(ED481D-2023-005)和竞争参考小组(ED431C 2020/01)以及西班牙政府的“软件多capa para el procesamiento online de datos lidar enfocado a la monitorización del transporte”项目(参考文献PDC2022-133851-I00,由MCIN/AEI/10.13039/501100011033资助)的资助。以及欧盟的“下一代欧盟”/PRTR。这项工作得到了MCIN/AEI/10.13039/501100011033和欧盟NextGenerationEU/PRTR资助的RYC2021-033560-I基金的部分支持。本文是在InfraROB项目(通过自主机器人解决方案和模块化保持道路基础设施的完整性、性能和安全性)的框架内进行的,该项目已获得欧盟地平线2020研究和创新计划的资助,赠款协议编号为。955337. 它只反映了作者的观点。欧洲气候、基础设施和环境执行机构(CINEA)和欧盟委员会均不对其所含信息的任何使用承担任何责任。披露声明作者未报告潜在的利益冲突。这项工作得到了地平线2020框架计划(Gobierno de España Xunta de Galicia)的支持。

ABSTRACTThis study investigates the erosive impact of wind-blown sand on earthen sites within arid environments through the establishment of meteorological observation equipment. Over a span of 47 months, a comprehensive approach encompassing numerical simulation, plume analysis, particle examination, three-dimensional scanning, and photo monitoring was employed to continuously monitor the patterns of wind-blown sand movement and the degradation of test walls. The study identifies six distinct zones extending from five times the windward side to ten times the leeward side of the test wall’s height. Notably, a negative correlation between captured particle mass and the height of the sand traps is observed, with 70% of particles concentrated within 50 cm from the base of the test wall. Three primary erosion mechanisms for wind-blown sand are elucidated, including frontal impact, side abrasion, and reverse sapping. Furthermore, the study highlights pronounced erosion at the base of the wall due to vortex flow, with depth erosion affecting the lower, side, and upper sections of the test walls. This paper delves into the erosion mechanisms and operational models of wind-blown sand flow surrounding discontinuous site walls, offering valuable insights for the conservation of ancient earthen sites.KEYWORDS: Ancient earthen siteserosion modelerosion ratewind-blown sand AcknowledgmentsWe would like to thank F.

ABSTRACTAs ecological architecture and green buildings have become essential in the fight against climate change, earthen architecture has an undoubted role to play in achieving this goal because of its numerous benefits. To help providing a better understanding of the behavior of earthen materials to fulfill modern architectural needs and to preserve earthen heritages, this study aims to investigate the effect of stabilization using Portland cement and quicklime and that of reinforcement using date palm fibers on the compressive creep, ultrasonic properties, and swelling of adobes, besides their impacts on physical characteristics. One of the earthen heritages in Algeria is taken as a case study, and various adobe mixes were examined to attain this objective. The outcomes revealed that stabilization overall improved the properties of adobes, unlike the mutable impact of fibers.

To help providing a better understanding of the behavior of earthen materials to fulfill modern architectural needs and to preserve earthen heritages, this study aims to investigate the effect of stabilization using Portland cement and quicklime and that of reinforcement using date palm fibers on the compressive creep, ultrasonic properties, and swelling of adobes, besides their impacts on physical characteristics. One of the earthen heritages in Algeria is taken as a case study, and various adobe mixes were examined to attain this objective. The outcomes revealed that stabilization overall improved the properties of adobes, unlike the mutable impact of fibers.

ABSTRACTRoman concrete is one of the most fascinating materials ever invented by humankind. Understanding the historical context and details of the production of ancient Roman concrete (ARC) is necessary to comprehend its nature. Recently, the interest in researching ARC has grown considerably, leading to several projects to describe its production. Remarkable properties were attributed to ARC, with durability emerging as one of the most relevant but also the most misunderstood. The reasons for the durability of Roman structures are still under investigation, and various hypotheses have linked its durability to the microstructure, or its chemical and mineralogical composition. In this literature review, historical facts contextualize ARC and detail the specific materials and methods used for production. It also becomes clear that the chemical, mineralogical, and mechanical characterization of ARC has begun to link research from different disciplines, providing an overview of this material, and exploring some of the unexplained facts that could potentially improve today’s concrete technology.KEYWORDS: Ancient Romeconcretedurabilitymicrostructurepozzolanic mortars AcknowledgmentsThe authors thank Prof. Dr.-Ing.

ABSTRACTThe diagnosis of cultural heritage structures is a challenging and delicate task. It involves the evaluation of potential pathological situations, the understanding of the origin of displacements and deformations, and the assessment of the state of conservation of building materials. Destructive and minor destructive techniques are mostly prevented from being used in the context of historical constructions and the complementary use of non-destructive techniques is often the only viable solution. This paper addresses the possibility of employing point clouds, widely used for representation aims, as a source of information to identify the deterioration patterns that can affect construction safety. The proposed methodology includes two approaches following a perspective based on simple and recurring elements that form the complex and unique shape of historical buildings. The geometry of structural elements guides the choice towards the computation either of the Z-coordinate of each point of the cloud or the Euclidean distance between the point cloud and an elementary non-deformed geometry fitted to it. By investigating several case studies and diverse deterioration patterns, the proposal establishes a framework to employ point clouds, together with other techniques, as an effective tool to support the diagnosis of heritage structures.KEYWORDS: Built cultural heritageconservationmasonry structuresnon-destructive techniques (NDTs)point cloudstructural diagnosis AcknowledgmentsThe authors wish to acknowledge Lorenzo Rossi and Francesca Gaglio for their preliminary work on the case studies, as well as Massimiliano Martino, Francesco Laccone, and Marco Callieri for their expert suggestions on some specific aspects of the methodological framework.Disclosure statementNo potential conflict of interest was reported by the author(s).

ABSTRACTThe Digital Twin (DT) technology has shown promise in transforming complex engineered systems. However, its adoption in the Architecture, Engineering, Construction, and Operation (AECO) field, particularly for Built Cultural Heritage (BCH) conservation, is still in its early stages. This study presents a systematic literature review of 85 academic publications to evaluate the current state of DT implementation in heritage building conservation and identifies areas for optimising preventive management. In addition, this review explores interpretations of the DT concept in this field, addressing overlaps with Historical/Heritage Building Information Modelling (HBIM), discusses DT functionalities and presents existing frameworks. The findings demonstrate the potential of DT to revolutionise BCH conservation through a holistic approach. However, further focus is needed on features and tools for enhancing performance-based management with targeted strategies and advanced data analysis. Future research should prioritise developing these aspects to fully leverage the potential of the DT paradigm in BCH conservation.KEYWORDS: Built cultural heritagedata managementdecision-makingDigital Twinpreventive conservation AcknowledgmentsThis work was supported by the doctoral Grant PRT/BD/152822/2021 financed by the Portuguese Foundation for Science and Technology (FCT), under MIT Portugal Program.Disclosure statementNo potential conflict of interest was reported by the authors.Additional informationFundingThe work was supported by the Fundação para a Ciência e a Tecnologia [PRT/BD/152822/2021].

In the last decade, the documentation of historical buildings has made tremendous progress in generalising the use of high-precision laser scanning and drone photogrammetry. Yet the potential of digital surveying is not fully exploited due to difficulties in manually analysing large amounts of collected data. Machine learning offers immense potential as a game-changer in building archaeology, especially for the documentation of structures composed of millions of units. This paper presents the first segmentation of large-scale surveys of historic masonry using machine learning, using the thirteenth-century Basilica of St Anthony (Padua, Italy) as a case study. Based on a drone survey of the north façade of the building (110 × 70 m), a state-of-the-art non-learning segmentation approach is described and its limitations for historical structures are illustrated. Then, a new workflow based on convolutional neural networks (CNN) is presented. The result is a precise mapping of about 300,000 individual bricks showing a large variety of formats and bonds. The automatic surveys are analysed using visual programming language (VPL), enabling a rapid and feature-based identification of building phases and repair interventions. The outcome demonstrates the validity of machine learning for the analysis of historical structures and its potential in the field of heritage.
