Geotechnology and community engagement drive historical heritage preservation

The preservation of historical and archaeological heritage is increasingly relying on advanced geotechnologies to combat the effects of time, environmental conditions, and urban expansion. Companies like Prime As Built 3D are utilizing non-destructive reality capture techniques, such as Terrestrial Laser Scanning (TLS), LiDAR, photogrammetry, and 3D modeling, to create high-precision digital representations of complex or fragile structures. These digital twins allow for detailed documentation, monitoring, and restoration without physical intervention.

In Brazil, efforts to protect cultural assets also emphasize the role of local residents and property owners. A manual authored by Carlos Magno de Souza Paiva and André Henrique Macieira de Souza provides practical guidance for those living in listed historical areas. This initiative stems from research conducted by the Federal University of Ouro Preto (UFOP) regarding how populations interact with urban heritage sites, such as those protected by IPHAN.
