Abstract
<p>Highway bridges are routinely rehabilitated or replaced in stages to avoid lane reductions. In recent years, the Ontario Ministry of Transportation (MTO) has seen an increase in inquiries and concerns from engineers and contractors related to staging. Some of the potential problems relate to settlement and movement of plastic concrete due to live load vibration, and shear and rotation at the construction joint, resulting in compromised reinforcement bond and reduced concrete quality at the construction joint. In support of a recent guideline advising designers of issues that shall be considered when designing bridges rehabilitated or replaced in stages, the MTO monitored the Hwy 401 Westbound Collectors Bridge over the Ramp from the Hwy 401 WBL Express to DVP/Hwy 404, during replacement. The paper describes the bridge’s behaviour as the closure strip concrete sets up. The relative ratio of strain between girders across the closure strip provides an indication of the development of load transfer over time.</p>

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
