Why using only condition scores to make replacement decisions is a trap and can lead to unwanted outcomes.

Conditions scores

Condition scores are typically an output from a condition assessment. Using only condition scores for decision making is not recommended. The primary problem with this approach is that it does not consider risk and/or value to the business. As an example, consider a typical power pole from an electricity distribution utility:

1. A poor condition pole in the middle of a desert serving a single home.
2. A poor but slightly better condition pole in the city serving 100 customers with a much larger safety risk and reputation impact. Which would you replace first?
