The 161.53 m high main tower of Ulm Minster is known as the highest church spire in the world – equally as impressive is the 29 m-long, 15 m-wide and 26-m high choir.
PERI systems are currently assisting with the extensive renovation work on the vaulted ceiling and the choir stalls as part of the restoration of the main tower and the north-east, 86 m-high choir tower.
The plans for the interior were missing, which proved to be an obstacle that PERI engineers were able to overcome with detailed 3D scaffold planning using the BIM methodology (BIM = Building Information Modelling). It was possible in the early planning phase to avoid possible collisions with historic construction materials by using 3D laser scanning and then transferring this into a 3D building model. The complicated, three-dimensional geometry of the choir’s interior was worked on using the free-standing, metric system grid PERI UP Flex, in 25-cm and 50-cm chunks with a total size of 13,000 m³.
The internal scaffold in the choir of Ulm Minster is currently being dismantled – the renovation work has already been concluded. From 2020 it will be open to visitors again. The 86 m high, north-east choir tower, which has already been surveyed using a drone from the Rheinland-Palatinate company Moselcopter GmbH, will be renovated next.
On the Ulm Minster project, Moselcopter GmbH performed scaled measurements for various application areas using drones.
The Moselcopter GmbH drone enabled image sequences from various perspectives and therefore records complex church structures.
