Comsa digitalizes the renovation of a century-old bridge in Cabrianes, Barcelona

Abstract

This article describes the digitalisation of a century-old bridge renovation in Cabrianes, Barcelona. Renovation projects involving historic infrastructure require teams to understand existing conditions, coordinate construction activities, and document changes carefully. Digital surveying and geospatial workflows can help capture the geometry of an existing structure and provide a shared reference for engineers and contractors. Such information can support planning, monitoring, and communication when original documentation is incomplete or the structure has changed over time. A digital workflow may combine survey measurements, imagery, 3D models, and project information, depending on the needs of the renovation. The challenge is to ensure that digital records remain accurate and usable throughout the project lifecycle. The topic illustrates how Geo-IT and digital construction methods can contribute to the modernisation of existing infrastructure while supporting the preservation and safe management of built assets.
