Construction History Tab

The Construction tab documents detailed information about the construction of the conduit. The tab also provides several fields related to risk analysis and replacement.

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 displays all construction records associated with the conduit. The sewer structure'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 Construction grid appears below. Sort records in the grid by clicking on the headings.  An up or down arrow (highlighted in orange below) indicate whether data appear in ascending or descending order.
