Vienna is gearing up for the future, and the newly constructed U5 line and the new U2 route are a key part of their plans: This will elevate the Pilgramgasse station to become an important interchange. To ensure that our experts were well prepared, the construction site was modelled ahead of time and coordinated with a point cloud. This allowed us to overcome major challenges such as the flow of traffic, limited room for manoeuvre and the protection of historical monuments.
U4 Pilgramgasse station
Not much room, not much time and ample consideration for monument protection: The renovation of the U4 Pilgramgasse station in Vienna was a high-precision undertaking. While works were underway, we took great care to manage traffic effectively, allowing us to ensure everything ran according to plan. No less than 2,910 m DN 120 bored piles, 482,850 kg of reinforcement materials and 2,600 m3 of concrete were installed
