Defining linear equipment

Linear equipment occupies a length of space such as an interstate or bridge. Create work orders for specific points or segments of linear equipment records, allowing you to track work orders, costs, and events along the equipment.

After you define a linear equipment record, add linear references. See Adding References to Linear Equipment.

Note: You can edit Equipment Length or Equip. Length UOM for an existing equipment record as long as there are no linear references that fall outside of the newly specified length in the Linear Ref. UOM.

If you edit the length of a linear equipment record, the system may automatically edit associated PM records when installation parameter PMRVCTRL is set to No. If the new equipment length falls on or within the length of the PM, the system automatically updates the To Point of the PM record based on the new equipment length. If the new equipment length falls outside of the length of the PM, the system does not update the PM record.

To define linear equipment:

  1. Select Equipment > Assets.
    Select Equipment > Positions.

    Select Equipment > Systems.

  2. Click New Record.
  3. Specify the information necessary to define the piece of equipment. See Defining Assets, Defining Positions, or Defining Systems.
  4. Specify this information:
    Equipment Length
    Specify the length of the equipment.
    Equip. Length UOM
    Specify the unit of measure for the Equipment Length.
    Linear Ref. UOM
    Specify the unit of measure for linear references. The system populates the from and to point unit of measure for work orders based on the Linear Ref. UOM. Linear references can have a different UOM than the Equipment Length. For example, if the system is integrated with ESRI’s GIS, the equipment’s map units may be in feet, but linear references like mile posts may be defined in miles.
    Ref. Precision
    Specify the number of decimal places to include in linear reference measurements.
    Note: If you do not specify a Reference Precision, the system automatically sets the precision to 0.
    Geographical Ref.
    Specify a geographical reference for the equipment.
    Inspection Direction
    Specify the typical direction in which an equipment inspection is performed.
    Flow
    Specify the typical direction in which the process flows.

    For example, you can specify the traffic direction of a street or the direction in which oil flows through a pipe.

    Linear Cost Weight
    Specify a number for the weighted cost of the equipment. This weight attribute determines the percentage of the work order costs the equipment is assigned when costs roll up from the child to the parent.

    For example, a railway asset in a city is shared by two different rail lines, and the maintenance costs of the railway asset must be applied to both lines. Without the weight attribute, the system would roll up all costs to both lines. If you want to split the costs evenly over both lines, you can enter a weight of 1 for both lines.
