Abstract

fetched live from OpenAlex

The city of Saskatoon supplies water to approximately 320,000 residents within the province of Saskatchewan via 1,192 km of water main at an estimated replacement cost of over CAD$2.5 billion. The city continually evaluates these linear assets within a long-term asset management plan that has contributed to reduced water main breaks (198 in 2020 compared to a 239 10-year average) and a more targeted water main maintenance and replacement program that is having an overall positive impact on the reliability of the system and citizen satisfaction. As part of this program, the city inspected 7.8 km of large diameter (600–1,050 mm) steel water mains in 2020 to assess their in situ condition. Assessing large diameter metallic pipelines was an expansion to the city’s overall inspection program, which had primarily focused on high-risk C-301 PCCP water transmission mains. Expanding the program to include metallic water transmission mains was driven by newly developed high-resolution free swimming inspection technology that would provide the city with the data they needed to make more informed decisions on these critical assets. The 2020 water main inspection program utilized multiple technologies to measure wall thickness and ovality, assess coating, and provide leak detection, all while keeping the water mains in service. In addition, structural (FEA) and remaining useful life (RUL) analyses were conducted to assist in repair recommendations, re-inspection intervals, and overall estimated pipeline life expectancy. Inspection results identified higher risk pipe sections at a highway crossing with both wall loss and out of roundness. A unique finite element analysis (FEA) was completed on pipes in this area that accounted for all these conditions—defects, out of roundness, and above normal external loading (significant depth of cover, highway crossing).

Teacher imitation

Not 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.
