Dynamic load test in Munich
Drop weight up to 12 t, evaluation per CAPWAP. For Munich and Upper Bavaria, with own measurement technology and travel distance about 4 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.
Munich gravel plain: quaternary gravel over tertiary molasse of alternating clay, silt and sand layers. The gravel carries well, but the boundary to the molasse lies at varying depth, and confined groundwater levels in the tertiary decide the behaviour.
A pile ending in the gravel behaves completely differently from one that reaches into the tertiary. If the layer boundary is assumed wrongly, the real bearing capacity deviates strongly from the calculated one, upward and downward.
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.
Munich and Upper Bavaria 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.
