Dynamic load test in Berlin
Drop weight up to 12 t, evaluation per CAPWAP. For Berlin and Brandenburg, with own measurement technology and travel distance about 3 hours from Gotha.
What the test delivers.
Bearing capacity of several piles within one day, evaluated per CAPWAP. The method per DIN EN ISO 22477-4 delivers shaft friction and base resistance separately and fits where the construction schedule does not allow a week of setup.
Details on the method are on the service page Dynamic load test.
Berlin sits on the Warsaw-Berlin glacial valley: boulder clay, sands of varying density, embedded peat and mud lenses, plus a high groundwater level. Density changes over short distances, exploration points on a 30 metre grid do not show the same picture.
Design based on experience values is often too far on the safe side here, in peat lenses too far on the unsafe side. Both look the same on paper. Settlement differences between neighbouring piles are the reason structures crack.
Dynamic load test in four steps.
- Expose pile heads, apply transducers
- Series of blows with drop weight, measure force and velocity
- CAPWAP model analysis, separation of shaft and base
- Report with bearing capacity and assessment per EA-Pfähle
The structural engineer gets numbers instead of assumptions. Measured bearing capacity allows a proof per Eurocode 7 without blanket safety margins.
Berlin and Brandenburg is geologically inconsistent. The test shows what the pile carries at exactly this spot, not what the ground model would suggest.
Differential settlement causes cracks, tilting and re-foundation. Tested piles are the cheapest part of structural stability.
