Review of the Asset Management, Inspection and Rehabilitation Work Required to Maintain Two Suspension Bridges, Angus L. Macdonald and A. Murray MacKay, in Halifax, Nova Scotia (Canada)
Bibliographic record
Abstract
The Angus L. Macdonald Bridge, opened in 1955, and the A. Murray Mackay Bridge, opened in 1970, are two suspension bridges that connect the cities of Dartmouth and Halifax in Nova Scotia, Canada. The Macdonald Bridge is 1347 m long (441 m main span) while the MacKay Bridge is 1236 m (426 m main span). The bridges are owned, operated and maintained by the Halifax Dartmouth Bridge Commission, doing business as the Halifax Harbour Bridges (HHB), whose main mandate is to provide safe, efficient, and reliable transportation infrastructure over the Halifax Harbour. A continuous effort has been made over the last 20 years to protect and extend the service life of these two critical bridges which need to withstand the harsh environmental conditions of Halifax. This paper showcases the advantages of collaborative effort between the Owner and Consultant, and the need for rigorous infrastructure maintenance and investment programs for suspension bridges.

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.
