### The stair and railing structural design is commonly delegated to the fabricator's engineer, who designs the members, connections, and railings for the loads and reactions and seals the calculations, while the SER coordinates the support points and reactions into the building structure. {note}
+### The contract documents shall state, for the stairs and railings, whether the design is fully detailed by the SER or delegated, consistent with the design-responsibility provisions of ANSI/AISC 303.
