Abstract
As part of the New York City's redevelopment of the far west side of the mid-town Manhattan, the No. 7 Subway Line Extension project will add 1.5 miles of twin bored tunnels to the existing subway line and two new subway stations. The underground construction has two major components: (1) Running Tunnel & 34th Street Station Cavern and (2) Tenth Avenue Station & Times Square Connection. The running tunnel contract will have a TBM launching shaft (Shaft A), an Adit connecting Shaft A to the running tunnels, and TBM Assembly Chamber at the southern end of the project, i.e., near 25th Street at Eleventh Avenue, where tunnel excavation begins. This paper will discuss challenges of the design and construction of Shaft A where it meets the Adit.

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
