| Calculate only for CCTV surveys with no Scoring Method set | Score only those CCTV surveys without a value in the Scoring Method field. Applies to the CCTV surveys included in the selection defined in the Data Source dialog. |
| Profile window size (m) |
Window size for the condition grade profile. Values from 0.1 m to 5.0 m. Note: The condition grade profile is an extension to the scoring for CCTV surveys. In addition to the normal scoring (peak scores, etc.) a survey can be broken down into grades. The percentage of grades present from 1 to 5 can be calculated for each pipe based on a given resolution (the profile window size). The condition grade profile is currently calculated only for structural scores, not for service scores. |
