What should I do if the BSR identifies a building feature that my safety case has not adequately assessed?

Do not treat the response simply as a request to add a description of the feature.

A description tells the regulator what is there. A risk assessment explains why it matters.

For example, if the issue relates to balconies, the response might need to consider:

• balcony type and construction
• materials
• attachment to the primary structure
• potential deterioration
• potential for fire spread
• consequences of structural failure
• inspection and maintenance arrangements
• available evidence about condition
• whether further investigation is reasonably required

Similarly, for precast structural elements, the relevant questions might include their structural role, support and connection details, robustness, deterioration mechanisms, alterations, current condition and the evidence relied upon to provide assurance.

The precise assessment should be proportionate to the feature and the credible building safety risk.

This is one of the fundamental differences between a descriptive safety case and a risk-based safety case.
