Specific challenges

Industrial, mining and agricultural assets are subject to harsh conditions due to chemicals used in some processes and air pollution. As for all key infrastructure, breakdowns that halt operations are a serious concern for site operators.

Industrial facilities specific challenges

  • Ageing of materials (steel, wood, concrete)
  • Concrete cracking or spalling due to alkaline reaction
  • Concrete carbonation
  • Chloride penetration in concrete cover
  • External chemical aggressions (polluted air, acid rain)
  • Chemical aggressions from stored products
  • Freezing / thawing cycles

  • Change in materials stored
  • Heavy equipment, vibrations
  • Evolution of standards (wind, earthquake, safety)
  • Design error, poor design or implementation
  • Material fatigue (moving wheel load effects)

  • Fire
  • Explosion
  • Excessive loading
