The Eucentre Foundation offers an integrated system of services in the field of Advanced Surveying & Digital Modelling<\/strong>, dedicated to surveying, digitisation, inspection, and structural monitoring of buildings and infrastructure. Through the combined use of high-resolution drones, laser scanning, BIM modelling techniques, visual and instrumental inspection, satellite monitoring, and artificial intelligence techniques for the automatic detection of damage, Eucentre is able to produce accurate and interoperable digital models, useful for structural assessments, life-cycle management of works, and – more generally – to support the digital transition of the construction sector.
\nA recent assignment commissioned by Studio Calvi Beam Srl made it possible to apply this methodology to a concrete case: the three-dimensional survey of a bridge over the Piave river, in the municipality of Longarone (BL), in the province of Belluno.<\/p>\n

The survey: method, technology, operational protocol<\/strong><\/h2>\n

The objective of the intervention was the complete geometric reconstruction of the artefact by means of drone photogrammetric techniques, with the ambition of producing a model of the bridge.
\nThe flight campaign involved a combination of manual and automatic trajectories to ensure coverage of all significant structural elements: piers, abutments and side elevations.<\/p>\n

Data processing and final product<\/strong><\/h2>\n

The images acquired by drone survey were processed using computational photogrammetry techniques, allowing the generation of a high-density three-dimensional point cloud. The point cloud thus obtained was subsequently imported into the BIM environment, where the information model of the work was developed.
\nThe resulting BIM model constitutes a reliable geometric and information basis for the subsequent definition of structural models aimed at assessing the seismic vulnerability of the infrastructure, as well as for possible structural analysis and life-cycle management activities of the structure.<\/p>\n<\/div><\/div>

Why this approach is relevant for professionals and clients<\/strong><\/h2>\n

The case of the Longarone bridge concretely illustrates the potential of a process that eliminates the need for direct physical access to the most inaccessible parts of the infrastructure, reduces survey time, and guarantees a level of geometric detail that is difficult to obtain with traditional methods. The integration of photogrammetric data and BIM modelling also opens the way to broader applications: from optimised maintenance planning to the development of dynamic digital representations of the infrastructure that can be updated over time and integrated with structural monitoring data.<\/p>\n<\/div><\/div>
