Recognizing the industry-wide adoption of Building Information Modeling (BIM), the 7th edition addresses digital data exchange protocol standards. It outlines how structural steel models should transition from design engineers to fabrication software to minimize geometric clashes and errors. 3. Structural Steelwork Execution Classes (EXC) Revisions to British Standards (BS EN, BS EN
, is the primary document used to standardise steelwork contract specifications in the UK. Its main goal is to ensure that fabricated and erected steelwork meets the design assumptions of standards like Eurocode 3 British Constructional Steelwork Association | BCSA Revisions to British Standards (BS EN

Crucially, the specification places a heavy emphasis on the "Execution Class." Under BS EN 1090-2, structures are categorized into Execution Classes (1 through 4) based on their consequence class and the risk involved. The NSSS 7th Edition mandates that most building construction falls under Execution Class 2 (RC2), providing clear guidance on the level of inspection and testing required for this category. This classification system allows for a proportionate approach to quality assurance, ensuring that resources are focused where the structural risk is highest.
