Abstract
Trenchless rehabilitation techniques such as cured-in-place pipe (CIPP) had been adopted by many municipalities in the province of Quebec to renew their aging sewer systems. Currently CIPP represents the largest market share of the utilized trenchless rehabilitation techniques in the province of Quebec. Considerable funding is being directed towards sewer systems rehabilitation projects. However, there have been little studies on the performance of the rehabilitated sewers, expected life of the liner, and its structural properties. Therefore, in an effort to address this shortcoming, this paper presents the outcome of a destructive testing protocol conducted on liners samples extracted from sewers rehabilitated using CIPP. Samples used in the testing process were collected from two locations in the sewer network that were rehabilitated over 1 decade ago. Testing the liner included examining the physical properties (e.g., thickness, annular gap, and so on), flexural properties, and tensile properties. The results demonstrate excellent current structural properties and strongly indicate that the liner will meet the anticipated lifetime. Deterioration of liner is expected to take place at a low rate. This conclusion remains valid as long as the current factors influencing structural properties do not change drastically over time.

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
