Abstract
The Inglewood Sanitary Trunk (IST) is a large diameter sanitary trunk located in Calgary, Alberta. Construction of Phase 1 was completed in November 2020 and consisted of approximately 3,500 m (2.2 mi) of 2,286/2,500 mm (90/98 in.) reinforced concrete pipe installed by microtunneling and approximately 270 m (0.17 mi) of 3,000 mm (120 in.) × 1,500 mm (60 in.) reinforced concrete box section installed by traditional cut and cover construction. Live connections were completed to 1,800 mm (71 in.) diameter pipe, a 2,100 mm (83 in.) × 1,500 mm (60 in.) concrete box section and the Bonnybrook Wastewater Treatment Plant (BBWWTP) headworks. Design of Phase 2 is currently nearing completion and consists of a twin 400 m–1,500 mm (60 in.) inverted siphon crossing of the Bow River. Construction is projected to be completed by 2024. When fully constructed, this upgrade will provide much needed additional sanitary capacity for a total equivalent population of 1.1 million residents and support growth to the 2,076 design horizon. This paper discusses the hydraulic concepts of the IST solution, design and selection of construction concepts, and a summary of the construction itself, including risk mitigation and project challenges overcome in the successful delivery of 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
