Abstract
The paper analyzes a case history of a challenging jet grouting excavation shoring project carried out in North Vancouver, BC. The new building comprises up to four levels of above ground structures with three levels of underground parking. The construction required vertical excavation of 9–11 m below the ground surface, extending up to 9 m below the groundwater table along the north side of the site. The project was complicated by the requirement of the shoring wall to act as a seepage cutoff with no allowance for external or internal dewatering wells. The shoring would also be required to act as a blind form for the construction of the building foundation walls. The soil conditions present at site are typical of portions of the Vancouver North shore; comprising heterogeneous granular fluvial deposits overlying silty sand glacial till with clasts of running sands, frequent cobbles, and random large boulders. The paper will describe the design elements and effectiveness of the jet grout system to create a secant pile shoring wall system. It also describes the lessons learned in the execution of jet grouting in the challenging site conditions.

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
