CBD substation building

Dr Mohammad Ghaffari · Arup · 2025 to now · Industry

Context

A live substation inside a city redevelopment precinct keeps critical electrical infrastructure running while everything around it changes. The building carried non-compliant exit geometry, and Performance Solutions that leaned on systems and procedures the asset owner needed removed.

My role

I was the fire safety engineer developing the performance-based design brief and Fire Engineering Report for the building.

Approach

  • Performance Solutions reworked to remove reliance on the transformer deluge system, gas suppression, staff training and on-site fire wardens.
  • Assessment of non-compliant clear width and clear height at the modified exit, with updated evacuation strategies and egress drawings.
  • Stakeholder comment rounds across the asset owner, developer and design team, and lodgement through the fire brigade consultation pathway.

Outcome

An approved egress and fire safety basis for the building that stands without the systems the owner needed retired.

  • Egress assessment
  • FRNSW consultation
