This study demonstrates the effectiveness of a multi-method approach for the restoration of a historic building (train station) in Poland. The project employed field investigations, laboratory analyses, and close-range photogrammetry to create a Historic Building Information Model (HBIM). This comprehensive data set informed the development of targeted conservation strategies that addressed the station’s specific needs while respecting its historical significance. Interventions prioritized the use of locally sourced and sustainable materials, minimized the visual impact on the exterior, and achieved net-zero emissions through improvements to the building envelope and a switch to a heat pump heating system. Additionally, an intelligent monitoring system was implemented to continuously collect data on environmental conditions and structural displacement. These data will be used to develop a predictive model for future maintenance needs, allowing for a preventative approach to conservation and minimizing resource consumption. Overall, this project serves as a model for integrating advanced technologies in historical building conservation, promoting sustainable practices, and ensuring the longevity of irreplaceable cultural landmarks. The key findings derived from this approach encompass a comprehensive assessment of the station’s condition, optimized conservation strategies, insights from HBIM modeling, and the ongoing benefits of the intelligent monitoring system. Field investigations revealed several areas of concern, such as structural cracks, material deterioration, moisture infiltration, and significant heat loss through the building envelope. This information was crucial for developing targeted conservation strategies. The use of internal thermal insulation systems, particularly capillary active mineral blocks, significantly improved thermal performance. Moisture management interventions, including the restoration of the rainwater drainage system and the application of moisture-proof insulation, reduced reliance on the municipal water supply. The intelligent monitoring system, with sensors measuring temperature, humidity, and structural displacement, plays a crucial role in ongoing conservation efforts. This system allows for continuous monitoring and the development of predictive models, ensuring targeted and preventative maintenance, reducing resource consumption, and extending the lifespan of the building.

This study investigates the impact of environmental conditions on the structural integrity and energy dynamics of historical masonry buildings using an IoT (Internet of Things) LoRaWAN-based (Long Range Wide Area Network) wireless sensor system. Over a six-month period, sensors were used to monitor wall temperature, wall humidity, air temperature, air humidity, crack width, and crack displacement. The data revealed significant correlations between environmental parameters and structural changes. Higher temperatures were associated with increased crack width, while elevated humidity levels correlated with greater crack displacement, showing the potential weakening of the masonry structure. Seasonal variations highlighted the cyclical nature of these changes, emphasizing the need for seasonal maintenance. Additionally, the findings suggest that managing temperature and humidity levels can optimize the building’s energy efficiency by reducing the need for additional heating or cooling. The use of LoRaWAN sensors provided real-time, remote monitoring capabilities, offering a cost-effective and scalable solution for preserving historical buildings. This study underscores the importance of continuous environmental and structural monitoring for the preservation of heritage sites. It also highlights the potential for integrating proactive maintenance strategies and energy optimization, ensuring long-term sustainability. By leveraging this IoT-based approach, this research contributes to the broader field of heritage conservation, offering a universal framework that can be applied to historical buildings worldwide, enhancing both their structural integrity and energy performance.

The available photogrammetric solutions, combined with properly conducted surveying measurements enable to create fully applicable, three-dimensional models of architectural structures, which can be applied in, i.e. protection of cultural heritage or conservational documentation. Currently, we can see an increase in use of digital non-metric cameras in a photogrammetric inventory of sacred monuments. Properly obtained and analysed data allow to create a digital model of an object, which later might serve as a basis for a vector image used for architectural and construction purposes. The paper presents the procedure of creation of 3D models of sacred historic monuments of relatively small sizes with the use of terrestrial photogrammetry and UAV using the Agisoft PhotoScan Professional software.

This study presents an integrated workflow for acquiring, processing, and fusing terrestrial laser scanning and Unmanned Aerial Vehicle (UAV) photogrammetric data to generate digital twins of heritage buildings within Heritage Building Information Modeling (HBIM) and Historical Geographic Information System (HGIS) environments. Using a historic wooden church as a case study, the proposed approach demonstrates improved completeness and geometric quality compared to UAV-only models. Dimensional differences between UAV-only and integrated models ranged from 0.8 to 3.2 cm, confirming internal consistency and suitability for documentation purposes. The workflow standardizes key stages of acquisition, scaling, and point cloud fusion, and establishes links between HBIM models at Level of Detail (LOD) 100–300 and conservation requirements. Additionally, it identifies integration points for Artificial Intelligence (AI)-based automation, supporting future developments in classification, segmentation, and conversion of 2D documentation into HBIM. The results highlight the potential of terrestrial laser scanning (TLS)-UAV integration for accurate, replicable heritage documentation and spatial–historical analysis.

The paper presents an analysis of the causes and effects of masonry vaults damage after a construction disaster in the historic church of St. George in Hajduki Nyskie (southern Poland), dated to the beginning of the XIV century. As a result of the collapse of the eastern gable wall, some parts of the vaults and a wooden roof were destroyed, as well as other structural elements and part of the church's equipment. The building combines late Romanesque, Gothic and Baroque style elements, representing high, trans-regional historical and artistic, religious and cultural values, in particular due to the valuable gothic wall paintings preserved in the nave. The paper presents the state of the building before and after the construction disaster as well as recommendations regarding the reconstruction of the vaults.

In material cultural heritage documentation, the use of measurement methods, i.e. photogrammetry and laser scanning, is becoming more and more common. The increasing availability of hardware and software allows to create the photorealistic models of objects documenting the heritage and the state of its preservation. The virtual object model can carry information about the dimensions, shape, color and texture of the documented object and it can be the basis for the documentation of the archaeological site, architectural and construction inventory, architectural and conservation studies and monitoring the condition of the object. In the paper presented an overview of the most important measurement techniques and methods for acquiring spatial data used in the documentation of monuments, with particular reference to photogrammetric documentation generated on the basis of data obtained from photographs made with the use of UAV. The heritage documentation presented in the paper were created using the Agisoft Photoscan software. The use of geographic information systems in storing, analyzing and sharing information about monuments was also discussed.
