Abstract
<p>The Oculus structure is the centerpiece of the World Trade Center PATH Transportation Hub in downtown New York City. The main structure consists of two inclined steel arches supported by steel columns, which are anchored onto cantilevers embedded in the transit hall's concrete slabs below. A segmental erection method was proposed to erect the Oculus arches, which significantly reduced the amount of temporary shoring required and allowed construction to proceed at a faster pace. During erection, a detailed geometry control procedure was developed involving multiple survey targets to ensure erection proceeded on the correct path. Bolted connections were proposed in lieu of welding in many locations to accelerate erection. The methodology for bolting such large pieces of steel was developed and designed, then optimized to achieve further schedule improvements.</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
