In the ever-evolving landscape of infrastructure heritage conservation, a groundbreaking study led by J. Xu from the Department of Architecture, Built Environment and Construction Engineering at Politecnico di Milano, Italy, is set to redefine how we approach the preservation of large-scale cultural assets. Published in the ‘ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences’—which translates to the Annals of Photogrammetry, Remote Sensing and Spatial Information Sciences—this research introduces an innovative workflow that integrates Hybrid Building Information Modeling (HBIM) with Geographic Information Systems (GIS). The goal? To tackle the unique challenges posed by infrastructure heritage sites that have undergone complex physical changes and have varied levels of archival documentation.
The study addresses a critical gap in the field: the lack of a comprehensive approach to document and conserve infrastructure heritage that has been altered by both natural and human-induced transformations. “Cultural heritage assets are frequently subjected to changes over time, often resulting in physical deterioration or the loss of structures, as well as the enrichment or loss of historical records,” explains J. Xu. “Our workflow is designed to adapt to these challenges, ensuring that we can create accurate, georeferenced, and semantically enriched digital records.”
The proposed methodology is particularly relevant for the energy sector, where infrastructure heritage often intersects with modern energy projects. For instance, historic bridges along railway lines, like those studied by Xu and their team, are not just cultural artifacts but also critical components of transportation networks that support energy distribution and logistics. By integrating HBIM and GIS, this research offers a robust framework for documenting and conserving these assets, thereby ensuring their continued functionality and historical significance.
The study validates its approach through three case studies: the Huli River Bridge III, the dismantled Mayan River Bridge, and the Muling River Bridge, all located along the Chinese Eastern Railway (CER) main line. Each case represents a different scenario, from well-preserved structures lacking archival records to physically lost structures with extensive documentation. “Our workflow demonstrates adaptability and contributes to both scholarly research and public engagement in infrastructure heritage conservation,” notes Xu.
The implications of this research are far-reaching. For the energy sector, the ability to accurately document and conserve infrastructure heritage can enhance project planning, reduce costs associated with unexpected structural issues, and foster public support through transparent and engaging digital records. Moreover, the integration of HBIM and GIS can facilitate better decision-making by providing a comprehensive understanding of the physical and historical context of infrastructure assets.
As the energy sector continues to evolve, the need for innovative approaches to infrastructure heritage conservation will only grow. This research by J. Xu and their team at Politecnico di Milano offers a promising path forward, one that combines cutting-edge technology with a deep respect for our cultural heritage. By making the integrated outcomes accessible via remote access and online publication using the ArcGIS platform, the study also ensures that these valuable records are available to a global audience, furthering the cause of heritage conservation and public engagement.
In an era where technology and tradition increasingly intersect, this research stands as a testament to the power of innovation in preserving our shared cultural legacy. As we look to the future, the insights gained from this study will undoubtedly shape the way we approach infrastructure heritage conservation, ensuring that these vital assets continue to serve both practical and historical purposes for generations to come.
