: Compliance with the RQSC-Buildings protocol is a mandatory clause within the specification.

Amend your NSSS clause from: "In accordance with NSSS 6th Edition" to: "National Structural Steelwork Specification for Building Construction, 7th Edition (BCSA/SCI, 2023)."

By implementing the 7th edition, project teams ensure that the execution of steel structures complies with BS EN 1090 (Execution of steel structures and aluminium structures), which remains a legal requirement for CE/UKCA marking in structural steelwork. Key Updates and Technical Changes in the 7th Edition

The 7th edition introduced several significant changes from the 6th edition:

This section saw extensive modification, bringing updated standards for corrosion protection and detailed new clauses regarding the specification, application, and testing of intumescent fire coatings .

Welding compliance has been tightened to match the latest iterations of BS EN ISO 5817 (Quality levels for imperfections). plates and bars

It is fundamentally based on Execution Class 2 structural steelwork.

3. Updated Welding and NDT (Non-Destructive Testing) Protocols

Includes annexes for Execution Class 3 for specialized or fatigue-loaded structures.

The BCSA has also published a "Model specification for the purchase of structural steel sections, plates and bars," which should be used in conjunction with the NSSS for procurement purposes.

The industry is moving aggressively toward Net Zero carbon goals. The 7th edition frameworks assist engineers and fabricators in tracking the embodied carbon of structural steel. It provides guidelines for: Selecting steel sections with high recycled content. Tracking Environmental Product Declarations (EPDs).
