Project description

The modernization of the round 3.8 km long western track section of the underground U4 between the stations Hütteldorf and Schönbrunn was completed in only 128 days construction period. The accomplished construction measures include the substructure improvement of the line, the rehabilitation of the superstructure, civil engineering works/reconstruction of the station, as well as the reconstruction of the 100 m long and 120 year old vault.

PlanRadar is a very useful and efficient tool for the complete documentation of construction projects.

“With PlanRadar we were able to carry out the construction documentation much faster than before, and thus save significant time when creating the reports. In particular, the construction progress is traceable anytime with the mobile application through simple and accurate location of the tickets on the plan.” – STRABAG AG, Dir. IC – Ingenieurbau
