Abstract
Three low-permeability cut-off walls were required for seepage control along the upstream toe of two new dams as part of the Lac des IIes (LDI) water management facility works. The LDI palladium mine is located 135 km North of Thunder Bay, ON, Canada. Jet grouting was used to create the low permeability cut-off walls by installing overlapping soil-cement columns. Jet grout columns were constructed using the double-fluid process. A comprehensive quality control program was implemented to ensure that specified geometric properties and performance requirements of the cut-off wall were achieved. An acoustic column inspector (ACI) tool was used to verify the diameters of the pre-production test columns. All jet grout locations were pre-drilled to prevent difficulties resulting from geological conditions and to ensure adequate penetration into bedrock. A three-dimensional profile of each jet grout column installed was generated and updated daily based on the results of pre-drill hole alignment measurements completed at every hole. In-situ permeability testing was also conducted during the pre-production test program and during the installation of the production columns. Permeability testing was performed in-situ and on cast cylinders of soil-cement samples. The low permeability cut-off walls were successfully installed and satisfied the specified performance criteria. Jet grouting was performed between the months of February and May under challenging winter conditions. This paper focusses on the quality management program (QMP) that was implemented to successfully complete this project.

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
