Digital surveying tools provide a cost-effective and fast alternative for building inspection, efficiently collecting vast amounts of data through a combination of sensors. Recent developments in computer vision and artificial intelligence (AI) enable the automated interpretation of this unstructured data, facilitating not only 3D reconstruction, but also the detection and segmentation of features with neural networks (e.g. visual defects, thermal patterns). This paper explores how digital tools can contribute to extending the lifespan of young heritage. A pipeline, where drone flights are combined with laser scanning and photogrammetry, is applied to a real-world case study: the church of Our Lady in Stockel (near Brussels), built between 1962 and 1967. By comparing archival material with our digital data sets, we uncover the causes and underlying deterioration patterns that might compromise the structural integrity of 1960s concrete churches. Finally, we explore the broader implications of surveying pipelines, not only for the traditional documentation of modern heritage but also for advancing future preservation and repair strategies.
