Condition Function Scoring
The fundamental principle of condition functions within the Metrix Asset Management System is a guided questionnaire that accumulates weighted scores throughout its completion – with the ultimate score yielding a condition result. There is no limit on the number of questions that can be set within a condition function. The only requirement is that the total weight of scored results sums to 100. See below for an example condition function.
Question 1 - Weight 40% - Are there any potholes occurring throughout the segment?
| Options | Option Score |
|---|---|
| No potholes | 0 points |
| Few individual potholes seen | 40 points |
| Potholes occurring in clusters | 80 points |
| Potholes grouped throughout segment | 100 points |
Question 2 - Weight 30% - Are the any shoves occurring throughout the segment?
| Options | Option Score |
|---|---|
| No shoves | 0 points |
| One shove formed outside of travel lane | 50 points |
| Multiple shoves and/or Shoves within travel lane | 100 points |
Question 3 - Weight 30% - Is there evidence of Cracking or Flushing?
| Options | Option Score |
|---|---|
| None | 0 points |
| Minor cracking evident | 20 points |
| Moderate cracking evident | 60 points |
| Significant cracking or flushing evident | 100 points |
Using the above example condition function as a template, the following results would be generated by the system as condition results.
| Question | Answer | Points | Weighted Result |
|---|---|---|---|
| 1 | Few individual potholes seen | 40 | $ 40 \times 40\% = 16 $ |
| 2 | One shove formed outside of travel lane | 50 | $ 50 \times 30\% = 15 $ |
| 3 | Moderate cracking | 60 | $ 60 \times 30\% = 18 $ |
| 49 out of 100 |
The weighted condition score is always out of 100 – with 100 being a poor condition and 0 being excellent. Metrix will map these scores to a default condition scale of 1-5 and these scales can be set by system administrators.
A score of 49/100 would map to a condition of 2.
The Metrix Asset Management System comes pre-configured with a default condition function for use by any newly created classifications. This function has one (1) question with five (5) answer options detailed below:
Question: Condition (Weight 100%)
| Options | Option Score |
|---|---|
| 1 | 0 points |
| 2 | 20 points |
| 3 | 60 points |
| 4 | 80 points |
| 5 | 100 points |
As seen above, the default condition function simply defers the condition result to the end user’s subjective assessment.
