Importance Level 4 (IL4) — Special Studies
Post-disaster serviceability design for critical facilities under the Building Code of Australia.
Importance Level 4 (IL4) facilities — hospitals, emergency services, and other critical infrastructure — must remain operational following a seismic event. The Building Code of Australia through AS 1170.4 mandates "special studies" for these buildings to demonstrate post-disaster serviceability and functionality.
We have specialist experience in IL4 special studies, working with design teams, constructors and building owners to meet these stringent requirements.
Scope includes
- Hospitals and health facilities
- Emergency services buildings
- Critical infrastructure
- Facilities with hazardous materials
- BCA compliance documentation
- Post-disaster assessment
