This inspection type adds only one component to the visual inspection: that is the “sounding” of the pole.
- 360 degrees of the pole are viewed and sounded. The pole is viewed from the top to the point where it intersects the groundline.
- It is struck 35-40 times
- The soundings are 6” apart from uniformly around the pole circumference from the ground line to 2’ above ground. The soundings are 12” apart from 2’ above ground to as high as can be reached from the ground.
- Data Collection: This is customer-driven, but the minimum requirement would be a GPS point taken at the pole. Notations of attributes of the pole, which include physical characteristics, would usually be on a staking sheet (height, class, vintage) and any hardware or pole issues.
- Data Delivery: Should be given in a suitable electronic format, typically a shapefile (.shp), Excel or Access format. Some utilities request a mark up of their maps for important information such as reject location. RAM generates detailed maps from the data acquired during the pole inspection and presents it in a book form at the end of the job.
- Accuracy: This is one step up from the Visual only inspection, but it is a small step. To improve accuracy, it should be paired with a boring option if the pole sounds hollow.
- Cost: This is a low cost, low accuracy pole inspection. It should be viewed largely as an inventory. Some decay issues will be revealed, but below ground and internal issues will be mostly overlooked.
