Abstract
<p>The new Evergreen Line is an 11 kilometre extension to the existing SkyTrain advanced light rail transit system in Metro Vancouver, British Columbia, Canada. The project scope includes design and construction of six new stations, expansion of one existing station, nine kilometres of elevated and at-grade guideway, and a two-kilometre bored tunnel.</p><p>This paper focuses on innovative design of the elevated guideway “Special Structures” where the standard precast segmental construction was not suitable. The necessity of constructing Special Structures is primarily driven by the complexity of the guideway and station geometry, and constraints imposed by properties, municipal infrastructure, railway tracks, and by connecting to an existing station. Construction challenges included working in constrained linear corridors, through multiple municipal jurisdictions, and over private properties and active railway lines.</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
