The construction industry is moving toward Building Information Modeling (BIM). The 7th Edition includes new clauses regarding:
The 7th Edition—along with its latest —establishes absolute uniformity in structural steelwork execution. It handles buildings engineered under static loading conditions based on Execution Class 2 (EXC2) , aligning with BS EN 1993-1-1 (Eurocode 3) or BS 5950 . For specialty or complex structures, the specification bundles detailed annexes mapped out for Execution Class 3 (EXC3) static and fatigue frameworks.
