Abstract
The project consists of a high-rise building supported on driven piles. Design objectives included determining the highest maximum long-term capacity which could be reasonably obtained from a drivability perspective, using readily available equipment. A pre-production test program was performed on 16-in. -diameter (406-mm-diameter) ASTM 252, Grade 3 (45 ksi and 310 MPa) steel pipe piles, having a wall thickness of 0.50 in. (13 mm). Based on evidenced capacities, including long-term set-up, a maximum allowable pile load of 600 kips (2,670 kN) was used on the project. The cost-effectiveness of the test program was evaluated by comparing the cost of a design using 600-kip allowable load piles to alternative designs using the same pile section, but assuming that various lesser testing scenarios had been performed, warranting higher safety factors. Six complete alternative foundation designs were performed for these lower allowable pile loads. Costs associated with the piles (based on production-pile driving behavior), concrete caps and mat, and construction-control methods were estimated for the redesigns. Foundation costs were evaluated for piles designed both with and without the benefit of capacity contribution from set-up. Cost differences among the various construction-control methods were determined in terms of total cost, and support cost. Pile-driving schedule impacts associated with the six alternative allowable loads were also estimated. Additional savings that resulted from applying test-program results to production piles which were damaged or terminated short were quantified.

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
