Monitoring the construction of S21 at Berlin main station

Automated monitoring of bridge, building and tunnel elements using geodetic and geotechnical sensors

Back

As part of the extensive construction work for the new underground S21 suburban rail line, a sophisticated geotechnical and geodetic monitoring system ensures the safety of Berlin’s main railway station. The surveillance measurements help mitigate risks to the ongoing rail operations and identify corrective measures early on. 120 bridge pillars are monitored before, during and after the entire construction phase. Displacements are measured and documented in detail.

The required sensor systems (water level gauges in the indoor shopping mall area, 4 total stations for the bridge pillars, 1 total station in the main hall and 1 total station for the U55 metro station) were designed and installed in three phases in spring 2015/2016/2018 and are operating since then.
