❌ “Only high-rise buildings need robustness checks.” ✅ Buildings as low as 4 storeys in consequence class CC2a still require robust detailing.

If you design buildings, manage risk, or construct multi-storey structures, understanding CIRIA C577 isn’t optional—it’s critical.

Published in 2005 (with updates and related guidance since), CIRIA C577 – Robustness of structures provides a comprehensive methodology for designing and assessing structural robustness. It bridges the gap between the high-level principles of Eurocodes (BS EN 1991-1-7) and real-world construction practice.
