What needs to be clarified
Survey the stair profile and landing connections, separating finish geometry from unproven structural deformation.
Materials to prepare
- Design profile and finished-floor levels
- Step/landing build-ups and agreed changes
- Full flight access and pre-finishing photos
What to compare
Number every rise and tread; measure comparable positions and surface slopes. Check both landing levels and nosings against design and selected applicable requirements. Repeat disputed readings, state uncertainty and mark concealed substrate areas.
Possible outcome of the analysis
A flight profile and deviation schedule may define further checks and correction options after reviewing junctions, without assuming one altered step resolves everything.
Limits of the conclusions
One step cannot represent a flight. Finish geometry establishes neither structural capacity nor the condition of guards, lighting or use.
