Amberley RAAF Base and AP6 Fire Works


The Amberley RAAF Base Redevelopment Project was a $6 billion upgrade of all major facilities that was completed over a five-year period. On the back of this major redevelopment was the requirement to upgrade the ageing fire main network, to bring the base in line with fire safety requirements. FB were commissioned by the Department of Defence to replace the existing trunk fire main system to a number of key base facilities.


Works Undertaken

  • 3km OD630 PE100 PN20 trunk fire main
  • 400m installed via trenchless HDD methods
  • Isolation and scouring of existing fire network for connections
  • Live connections to existing fire network
  • Commissioning of new trunk fire main
  • Decommissioning of existing fire infrastructure


Highlights, Innovations and Key Risks

  • Entire pipeline was required to be butt welded, requiring innovative methods of completing cross-connections, in-trench welding, and a comprehensive weld testing regime
  • Construction through PFAS contaminated ground requiring testing and management of contaminated spoil. Early identification and classification of contaminated areas was key to the success of the project
  • Utilised HDD technology to avoid protected vegetation along the alignment
  • A large number of unknown services were encountered. Comprehensive service location and vacuum excavation was required to locate and survey all potential conflicts
