Condition Assessment Techniques

Below is a list of techniques that can be used to determine the condition of an asset.

These techniques can be divided into two main categories: Non-destructive Testing (NDT) and destructive testing which commonly entails taking a sample of the material to be assessed.

Non-destructive Testing / Assessment

Non-destructive Testing is any method of testing the properties of materials without the need to take samples and therefore resulting in damage to the material.

• Acoustic Logging
• CCTV - Mainly applicable to de-watered pipes such as sewer or stormwater pipes
• Ground-Penetrating Radar
• Laser Profiling
• Pit Depth Measurement
• Road Roughness Survey
• Smoke Testing - Mainly applied to Sewer Pipes
• Stress Wave Non-Destructive Testing
• Thermal Imaging
• Ultrasonic Wall Thickness Measurement
• Vibration Monitoring
• Visual Condition Inspection
• Video Based Condition Assessment
• Video based Visual Condition Inspection - Roads

Destructive Testing

• Coupon Removal
• Accelerated Pavement Testing
• Pipe Sample Removal
