Structural Calculations · Staircases
Do I need structural calculations for a staircase?
For a new or changed structural staircase, yes. Steel and concrete stairs need stamped calculations, and steel works need a specialist stamp.
The short answer
Yes, for a new staircase or a change to a structural one, such as a new internal stair, a steel external stair or a stair to a roof room or mezzanine. The calculations check the stair, its supports and the slab or wall it connects to, and are stamped for the approvals. Steel stairs also need specialist verification and a stamp.
