SEISMIC UPGRADE OF THE CANADIAN PARLIAMENT BUILDING
Bibliographic record
Abstract
Centre Block, Canada's heritage designated federal Parliament building located on Parliament Hill, Ottawa, was constructed in 1916 after fire destroyed an earlier building of the same name that occupied the site. The building, and its iconic 92 m tall Peace Tower, is currently undergoing a major rehabilitation that includes conservation of its heritage fabric, modernization of its mechanical and electrical systems, enclosure of its interior light courts with glass roofs, the addition of a large multi-level below grade Parliament Welcome Centre, and a comprehensive seismic upgrade. The seismic upgrade is particularly complex due to the historic materials used in Centre Block's construction and the heritage finishes that adorn its walls, floors, and ceilings. At the schematic design level, two general upgrade approaches were explored: a conventional seismic upgrade and an upgrade incorporating seismic isolation. Although not commonly used in moderate seismic zones, the upgrade incorporating seismic isolation was found to be highly effective, less intrusive and to provide a greater level of protection to the building and its finishes. This paper provides an overview of the existing building and its historic construction materials. A summary of its current seismic performance level, key vulnerabilities, and goals of its seismic upgrade are discussed. Key decisions relating to the seismic isolation system design and superstructure strengthening are explained.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
