The Construction tab allows agencies to record detailed information about the construction of the pipe. It also documents location information, such as the benefit district, section, or township. Finally, the tab provides several fields for risk analysis and modeling.

If these fields are completed, then the program will automatically calculate the Length field on the Attributes tab. |

Risk Calculation
Risk calculations are a way for agencies to evaluate where potential weak spots in their infrastructure are.
Criticality |
Rates how important the asset is. This rating should be a whole number based on a scale that the agency uses. A higher number means more risk. Example: On a scale of 1 to 100 this asset is pretty import so it has a Criticality score of 85. |
Probability of Failure |
Rates how likely the asset is to fail. This rating should be less than one because it represents a percentage. Example: This asset will only fail about 5% of the time so it has a Probability of Failure of (5/100) = .05 |
Mitigation |
Rates any factors that have been put into place to mitigate the failure of the asset. This rating should be less than one because it represents a percentage. Example: To offset the failure of this asset we have a backup, though it will only make up for about 30% of the loss. This asset has a mitigation score of (30/100) = .3 |
Risk |
Represents how much risk the asset represents. Calculated based on: (Consequence of Failure x Probability of Failure x Mitigation). Example: This asset represents a 85 x .05 x .3 = 1.275 risk to the system. |
Construction Grid
The Construction tab also contains a grid that displays all construction records associated with a particular pipe. The sewer pipe's Present Value and Remaining Life are displayed above the grid. These values are defined by the deterioration rates set up in the Construction record and are updated automatically by the system.
A sample of the grid headers appears below. Sort records in the grid by clicking on the headings. An up or down arrow (highlighted in orange below) indicates whether data appear in ascending or descending order.
To access the Construction records, select Sewer > Construction Records.
