Evaluating the Effects of Host Pipe Shape on CIPP Thicknesses Using MOP 145 Design Methods
Bibliographic record
Abstract
ASCE Manual of Practice 145 (MOP 145), Design of Close-Fit Liners for the Rehabilitation of Gravity Pipes, provides design guidance for close-fit liners in gravity pipeline applications for a wide range of cross sections. With the increase in functionality for non-circular cross sections comes a significant increase in the geometric information required to facilitate the design process. Our paper involves a review of multi-sensor sewer inspections (i.e., LiDAR or laser scanning and SONAR) completed in Winnipeg, Manitoba, Canada, and the impact of the observed variation in cross section has on the required liner thicknesses using the MOP 145. The findings of this research are concluded with recommendations for data collection by owners and engineers during the design phase to facilitate a fair and level tendering process. The intent is that our findings will help the industry in developing tailored tendering strategies aligned with MOP 145.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
