Abstract
The recently developed instrumented Becker penetration test (iBPT) when configured as a reusable test pile provides direct measurements of strain and acceleration at up to five locations along the drill string. This paper describes details of the test system, measurements, and presents representative results from an iBPT sounding performed at a predominantly fine sand site where indicator test piles were previously installed. The ability of the iBPT system to estimate equivalent SPT N60 values at the site is first demonstrated. Representative iBPT pile driving analysis (PDA) measurements obtained from the multiple modules at the base and along the shaft during field driving is then presented. Finally, a new multistage signal matching approach for estimating the distribution of resistance along the pile, and pile ultimate capacity is demonstrated using individual iBPT module dynamic measurements.

Full frame distilled prediction
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
