As-Built and As-Maintained: Two Different Compliance Questions
Accessibility and code compliance for walking surfaces come down to conditions that can be measured on site: the width and continuity of an accessible route, the change in level at a threshold, the running and cross slope of a ramp, handrail geometry, and the condition of the surface along the route.
Those are the builder's side of compliance. Whether a design professional met the professional standard of care in producing the design is a separate question requiring a licensed design professional of that discipline, and it is referred rather than absorbed. The distinction is stated explicitly in every report.
Compliance is also not fixed at handover. A route that was compliant on the day it was signed off can be non-compliant a year later because matting has been laid across it, a settled slab has opened a differential at a joint, or seasonal equipment has narrowed the clear width. Those are maintenance findings as much as code findings, and they are documented against both the requirement and the operator's own practice.
