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

❌ “My software does all this automatically.” ✅ No software can interpret tie forces and notional removal logic—engineering judgement is required. ciria c577

With the rise of BIM and parametric design, CIRIA’s methodology is increasingly being automated. Some engineering firms now script notional removal checks into their analysis software. However, the —why a building is robust—still comes from the principles in C577. ❌ “Only high-rise buildings need robustness checks
