The Elbe Philharmonic Hall is a stunning landmark in Hamburg. It is a highly complex building with densely intertwined pipes, tubes, steel and concrete. The undulating glass crown of the building is home to two concert halls, a five-star hotel with 250 rooms, restaurants and about 47 exclusive penthouses. The Kaispeicher, a historic warehouse, houses a third concert hall and a parking garage for more than 500 cars.

HOCHTIEF ViCon supported the contractor right from the tender phase, in which it prepared a simplified 3D model of the building and a video animation. In the course of the project, the 3D model was regularly updated based on 2D drawings.

The model formed the basis for 3D clash detection conducted by HOCHTIEF ViCon. This test detected geometrical conflicts between trades so that collisions were avoided right from the planning phase and even before construction started. An on-site iRoom was used to discuss the results of the 3D clash detection test. On interactive projection screens, plans and models could be tagged with comments and sent to specialist planners.

The model also served as the basis for 4D construction sequence planning. Using the 4D model, conflicting schedules could be identified and remedied in time. In addition, it was used to monitor progress by means of a target/actual analysis. Webcams on the building site portal also served to document construction progress.
