Saunderson PRV Lower Townsite Supply Lines HDD
Bibliographic record
Abstract
The Saunderson PRV project is a multi-year project to upgrade water supply for the Lower Townsite (LTS) neighbourhood in Fort McMurray, Alberta. The project includes the construction of a new PRV chamber, extension of the existing primary high pressure water supply line, and the installation of a new supply line from the existing LTS Reservoir in the Abasand Heights neighborhood to the new PRV chamber by horizontal directional drilling (HDD). The focus of this paper is on the design and installation of the 445 m long and 914 mm diameter HDPE DR9 directionally drilled supply line crossing of Highway 63 from the LTS to the Abasand Heights plateau, a topographic elevation difference of approximately 65 m between entry and exit. Project complexities resulting from the elevation difference between drill entry and exit included risk of flush-backs during reaming passes, overbreak pipe support for pullback, buoyancy control requirements during pullback, and annular space grouting post-installation.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
