Pipe Defects

Pipe Defect records provide detailed information about each defect, as reported in the pipe's most recent inspection. An example appears below:

Pipe Details

Field	Function
Source	Indicates which Inspection module the defect came from.
Distance	Measures how far from the beginning of the inspection that the defect was found.
Defect Obs Text	Describes the defect.
Defect #	Displays the system-generated identifier for the defect.
Selected for Repair	Indicates whether the model found the defect to be in need of repair.
Repair #	Specifies which task in the Pipe Work Tasks grid will fix the defect.
Continuous Defect	Indicates whether this defect is part of a continuous defect. (More information about continuous defects may be found below.)
Contin Defect Obs #	Indicates where this observation falls along the length of the defect if it is part of a continuous defect.
End Contin Footage	Indicates the end footage for a continuous defect.
Start Clock End Clock	Specifies the location of observations that run along the circumference of a pipe, as compared to positions on face of a clock. Use the Start Clock field to enter the clock position where the defect starts. Follow the defect clockwise and use the End Clock field to mark the end of the defect.
Struct Rating	Indicates the Structural Rating found on the Inspection Observation record. (More information about pipe ratings may be found below.)
O&M Rating	Displays the O&M Rating found on the Inspection Observation record. (More information about pipe ratings may be found below.)
Flow	Specifies the amount of flow remaining after rehabilitation.
Building Connection	Indicates whether this observations is actually a connection to a building.
Lateral Location	Indicates the direction that the lateral enters the pipe.
Location	Specifies the site of the defect in the pipe.
Observation	Displays the system-generated, unique ID for the observation.

Continuous Defects

Continuous defects are tracked in the Pipe Analysis Details dialog in the following manner:

The system shows the first and last records for the continuous defect.
The system adds records as follows for all continuous defects between the first and last records:
- For PACP continuous defects, the system adds a replica of the initial defect every 5 feet.
- For TV continuous defects, the system adds a replica of the initial defect every 5 feet unless there is a value for Pipe Section Length in the Pipe Inventory record, in which case, it uses that value instead.
- The total length of the continuous defect can be seen in the first continuous defect under the Continuous Length field.
- Every Continuous Defect record, whether the starting value, ending value, or an added record, has the Continuous Defect checkbox marked as "True."
- The Location field indicates whether it is the starting, ending, or added continuous defect record.

Pipe Ratings

Pipe Ratings are recorded in the Pipe Analysis Details dialog as follows:

PACP Observations - A defect can either be a Structural defect or an O&M defect, depending on which observations are recorded in the PACP Inspection module.
TV Inspection Observations - Ratings are assigned as follows:
- The rating from the TV Observation is used. In the example below, the rating is a "3."
- The Rating is assigned either the Structural Rating and/or the O&M Rating depending on the Structural # and Cleaning # for that defect. If either value is greater than "0," then that rating is assigned in the Pipe Analysis Details dialog.
