Close-Interval Surveys

QualCorr has completed thousands of miles of Close Interval Potential Surveys (CIPS) across the United States and beyond. These surveys are carried out to provide a profile of the potential level along the length of a metallic structure. The profile can include both ‘On’ and instantaneous ‘Off’ potentials to assess the Cathodic Protection performance. This survey procedure can also be used to identify areas affected by interference. We can obtain other information during these surveys to include:

  • Sub-meter Centerline Locating
  • Depth-of-Cover
  • Condition Assessment & Identification
  • Installation of Marking Devices
