Abstract
Typically, impact hammer selection must consider drivability, testing requirements (assuming the same hammer is used for dynamic load testing), and the potential for pile damage, especially where piles are installed into dense or hard strata. There are various guidelines regarding the maximum allowable driving stresses and the maximum recommended driving energy of the impact hammer to avoid damaging steel pipe piles and H-piles during installation under such conditions. In a companion paper, these guidelines were reviewed to develop a preliminary screening tool for selecting an impact hammer to safely install and test steel pipe and H-piles. This paper will examine a case history where an H-pile was damaged during installation. The paper will review the hammer selection against this screening tool and how the pile damage could have been predicted using the screening tool in conjunction with sophisticated simulation and analysis software. The paper will also demonstrate the importance of interpreting the results of a pile driving simulation properly to ensure a reliable prediction of the actual pile driving conditions.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
