 The Basilica di San Giacomo in Colmo, Italy, has been undergoing restoration and conservation efforts since 2022. A scantabiam approach was employed using high-detail 3D survey techniques to capture the building's exact shape and annexed structures. Through various modeling strategies, a single 3D model was created which provides essential support for planning the restoration activities and gives experts a single tool for managing data throughout the construction process. Additionally, the model can be updated with geometric and non-geometric information, providing a powerful tool for future activities like installing a monitoring system to detect any displacement of bearing elements.
