The restoration of the Arch of Augustus in Aosta, promoted by the Superintendence for Cultural Heritage of the Autonomous Region of Valle d'Aosta, represents an exemplary intervention that combines conservation, scientific investigation and digital innovation. The objective of the work is to preserve and enhance one of the most significant monuments of Alpine Roman times, built in honor of Augusto Imperator to celebrate the Roman victory over Salassi, and which over the centuries has become a symbol of the city's identity. The project documentation was organised with a BIM (Building Information Modelling), which allows integration between 3 D surveys, degradation mapping, diagnostic steps, interventions. This model guarantees complete traceability of restoration interventions, and constitutes a digital archive, which can be updated and functional for scheduled maintenance over time. The BIM model, developed in collaboration with the University of Brescia, included orthophotos, environmental data, structural and historical analyses, integrating them into a single accessible and interoperable information ecosystem. At the same time, historical research has experienced significant acceleration: archival analysis has led to the chronological systematization of previous interventions, from medieval times to today, with contributions from figures such as Promis, D'Andrade, Schiaparelli The stratigraphic reading of the changes – from the disappearance of the attic and inscriptions to the remakes with artificial puddinga – has become an active part of the historical narrative of the monument. Research is also continuing through new diagnostic technologies, CFD environmental modelling and microclimatic assessments, which offer an evolving image of the relationship between the monument and environment. Finally, the intervention proposes a replicable model of restoration in the Alpine context, capable of combining historical knowledge, material protection and technological innovation in a very hard climatic context.

Abstract
The restoration of the Arch of Augustus in Aosta, promoted by the Superintendence for Cultural Heritage of the Autonomous Region of Valle d'Aosta, represents an exemplary intervention that combines conservation, scientific investigation and digital innovation. The objective of the work is to preserve and enhance one of the most significant monuments of Alpine Roman times, built in honor of Augusto Imperator to celebrate the Roman victory over Salassi, and which over the centuries has become a symbol of the city's identity. The project documentation was organised with a BIM (Building Information Modelling), which allows integration between 3 D surveys, degradation mapping, diagnostic steps, interventions. This model guarantees complete traceability of restoration interventions, and constitutes a digital archive, which can be updated and functional for scheduled maintenance over time. The BIM model, developed in collaboration with the University of Brescia, included orthophotos, environmental data, structural and historical analyses, integrating them into a single accessible and interoperable information ecosystem. At the same time, historical research has experienced significant acceleration: archival analysis has led to the chronological systematization of previous interventions, from medieval times to today, with contributions from figures such as Promis, D'Andrade, Schiaparelli The stratigraphic reading of the changes – from the disappearance of the attic and inscriptions to the remakes with artificial puddinga – has become an active part of the historical narrative of the monument. Research is also continuing through new diagnostic technologies, CFD environmental modelling and microclimatic assessments, which offer an evolving image of the relationship between the monument and environment. Finally, the intervention proposes a replicable model of restoration in the Alpine context, capable of combining historical knowledge, material protection and technological innovation in a very hard climatic context.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
