Level of preparedness of accessibility standards in Canada to address the needs of people with disabilities in heritage buildings—reconnaissance survey
Bibliographic record
Abstract
Canada is making significant strides toward becoming a barrier-free nation by 2040. The CSA/ASC B651 standard outlines the minimum accessibility requirements in built environments. This study investigates the status of the CSA/ASC B651 in meeting the needs of individuals with disabilities. A reconnaissance survey was conducted by participants with diverse abilities to identify barriers encountered when visiting heritage sites. While the standard has proven adequate in addressing most barriers encountered, the findings reveal that significant issues arise from the inconsistent application of the standard. The results illustrate the complexity involved in addressing the needs of those with disabilities. Vehicular access and passenger pickup areas represented 31% of barriers faced by participants with physical disabilities. Inaccessible exterior circulation represented 37% of barriers faced by people with hearing disabilities. Building interiors and interior circulations represented 44% and 36% of barriers faced by people with visual disabilities and intellectual/developmental disabilities, respectively.

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.
