Design Responsibility The package’s bespoke architectural metalwork and feature stair systems are Contractor Design Portion. The design team specifications set performance requirements and design intent only; the Contractor develops that intent into a complete, buildable design, including structural calculations, fabrication and shop drawings, connection design back to the primary and secondary structure, the Building Regulations approvals that depend on them, and coordination at every interface with adjoining trades. Naming a specific product or finish does not relieve the Contractor of that responsibility. This includes the full structural design of the Helical, Spiral, West, East and South feature stairs; structural adequacy and loading design for all balustrades, guarding, working platforms and walkways, including permanent fall-restraint systems and their certification; and a condition-survey-led repair method and specification for every refurbishment item.
