Abstract

Photogrammetric surveys for geological excavation documentation are standard practice in tunnel construction, benefiting from the sector's ongoing digitalization. However, the application of photogrammetry often remains confined to geological assessments. By creating comprehensive 3D models of excavated tunnels, it is also possible to evaluate engineering aspects. In this respect, the documentation of the as-built condition is of particular interest, that is, the effectively applied shotcrete, which is a novelty application in the field of tunneling. This contribution presents the photogrammetric recording process used in the Angath test gallery, a scientifically monitored gallery that is part of a new railway line in Tyrol, Austria. The evaluation of the overall photogrammetric model and the findings obtained from it are highlighted.
