Failure investigation

Forensic engineering and expert witness

Determining the root cause of failure can be key to avoiding further costly mistakes, affecting both business performance and hard-earned reputations.  Edif ERA’s asset specialists and laboratory facilities help manufacturers, operators and other stakeholders understand why the failure occurred, the contributing factors, and provide information to prevent similar future events from taking place.

We utilise our knowledge, expertise and analytical facilities to undertake forensic investigations and carry out root cause analysis of equipment from plant to component level.  We routinely support manufacturers, owner operators, insurers, loss adjusters, lawyers and stakeholders across all business and industrial sectors.


  • Single or joint expert witness testimony
  • Preparation of legal arguments
  • Site and laboratory based investigations
  • Root cause analysis
  • Capability on static, rotating, electrical and electronic equipment
