Risk Based Inspections : Probability of Rapid Deterioration, Damage or Failure Score

The probability of rapid deterioration, damage or failure is a function of the following:

• Current condition of a structure and/or element of a structure, i.e. the condition of the structure and/or element of the structure at the last recorded General or Principal Inspection.
• Rate of deterioration, which is dependent on the structure specific characteristics and the severity of exposure to external influences.
• Potential failure mode, e.g. brittle or ductile failure.
• Inspectability, i.e. the ability to adequately inspect all parts of the structure
• Principal Inspection Interval, e.g. time-based every 6 years or risk based decreased/increased interval
