Checklist for Fire Engineering Assessment (Singapore Chapter)

Alternative approaches to address building modifications and compliance for fire safety

With the prevailing building codes and standards changing to address new technologies and market trends, existing buildings may be outdated or deemed to be non-compliant during the stage of upgrading. Innovative fire safety engineering designs for existing building designs are therefore required to ensure continuity and code compliance.

Through in-depth knowledge of prescriptive and performance-based approaches, SHEVS can provide the most appropriate and effective Fire Engineering Assessment to seal the gaps for code compliance.
