Dynamic load test in Frankfurt am Main
Drop weight up to 12 t, evaluation per CAPWAP. For Rhine-Main region, with own measurement technology and travel distance about 2 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.
Frankfurt clay, a tertiary, overconsolidated clay with embedded limestone bands, underlain by Frankfurt limestone. The clay creeps under sustained load, its stiffness depends on stress level and time. Combined pile-raft foundations are standard here, especially in high-rise construction.
Creep deformation does not show up in a short-term test or in a calculation with experience values. Whoever sets the load split between raft and pile without measurement has an assumption, not a proof.
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.
Rhine-Main region 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.
