1. The pole will be sounded with a hammer from the base of the pole to as high as the inspector can reach to locate interior pockets of decay.
  2. If any decay is suspected, the inspector will bore up to two separate inspection holes into the suspected area to determine if any decay is present. The inspector will analyze the boring to determine depth of penetration of preservative and if any decay is present. A shell thickness indicator will be used to determine existence and extent of any interior decay.
  3. The pole will also be bored and analyzed at a 90-degree angle to where the original boring occurred.
  4. Photo of each bore sample will be taken alongside of the penetration gauge.
  5. All inspection holes will be plugged with tight-fitting treated wood or plastic plugs.
  6. Site Photo of the pole to include manufacture tag.
