Risk Based Inspections : Consequence of Failure Score

• Magnitude of Failure of the structure or its elements ; and
• Socio-Economic importance based on the features importance, i.e. the route carried/obstacle crossed and the structure importance, i.e. which parts of the community it services .

The scores for each of these criteria are combined using Equation 3 below:

CF = 0.6 x MoFS + 0.40 x SEIS   but not < 1 or > 100

Where CF = Consequence of Failure
MoFS = Magnitude of Failure Score
SEIS = Socio-Economic Importance
