Abstract
In recent decades, there has been a significant increase in the construction of high-rise buildings due to the use of highcapacity foundation piles.Multistage (bi-level/two-tier) instrumented bidirectional static load tests (BDSLT) must be used to verify the capacity of these piles.This article describes the successful execution of an instrumented bi-level bored pile test socketed in the layered rocks of a high-rise building on Palm Jumeirah Island, Dubai.In order to ascertain the behaviour of the pile-rock interaction, a 1200mm pile at a depth of 25.60m was instrumented using ten levels of vibrating wire strain gauge technology and load tested up to 67596 kN using 6x9000kN sacrificial hydraulic jacks in two levels.The settlement recorded was 39.50mm, and the unit shaft friction calculated was in the range of 1000 kPa at the ultimate test load.It was found that the side resistances of the rock layers were higher than the values initially selected for the foundation design, indicating that the results of this bi-level load test accurately represented the true state of the subsurface.The design skin friction values were modified, considering the pile test and ground results, to provide the project with an economically feasible outcome.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
