Full Network: Every asset of this type (e.g., gravity main, lateral, manhole) will receive a score for this LOF.

Facility Selection: Every asset of this type (e.g., gravity main, lateral, manhole) that is within the static selection will receive a score for this LOF.

Zone: Every asset of this type (e.g., gravity main, lateral, manhole) that is assigned to the zone selected will receive a score for this LOF. Please note that "zone" is an attribute field for each element type. If there are no values in this field, there will be no options in the zone drop-down menu.

Step 2: Choose a Category


Normalize value: Choose a field from the dropdown to divide the value by. For example a user might select pipe length to generate a resulting “number of incidents per pipe length” value. NOTE: This option is not available if the "Value" field contains non-numerical results (i.e., material results displayed in the above).


In Step 5, consequence scores will be defined based on values shown in Step 4. Depending on the parameter type selected in Step 3, the values may be text or numerical which require different types of scoring. For example, if pipe material is being evaluated, a text field will be scored, so there cannot be a range of values to score. A score would be assigned to each unique material type.  But with a LOF score on pipe diameter, a numerical value, scoring could be done on individual values or on a range of values.

The following dialog demonstrates following dialog box demonstrates scoring ranges based on install dates where the number of classes as well as breaker values to create custom ranges can be defined.

The following dialog box shows the discrete text values returned from scoring on a text field. In this scores will be assigned to specific values. The number of classes does not apply when using text values.


Equal Interval, Natural Breaks, and Quantile methods can be used for automatically assigning breaks to ranges of numerical values:

Quantile - assigns Assigns the same number of data values to each class.

Equal Interval - divides Divides the data values into equal-sized classes.

Natural Breaks - classes Classes are set where there are large differences in the data values.


Pipe Attribute - Predict the likelihood of failure of each asset based on it's direct attribute data (e.g., install date).

Select a facility attribute field, or choose other to select any other field associated to the asset. Please note that the options shown here will vary depending on what asset type the LOF is scoring.


Critical FacilitiesUse the location of critical facilities (e.g., hospitals) to assign higher LOF to nearby or associated assets.


Facility Layer - The background GIS layer to be used in the COF.

Facility ID Field - When a field is selected, InfoAsset Planner will omit the spatial search and simply apply True/False values based on direct assignment of Assets to critical facilities. Each critical facility (e.g. hospital) can be assigned one asset (e.g. pipe) using this field. Set this value to Blank to use the spatial search.
