 Spatial Sampling of Wooden Electricity Poles

Sampling can be used as an effective and efficient means to provide a high level of assurance for assets.  In our case study we look at how a practical sampling scheme was designed to verify the accuracy of Western Power’s database of approximately 80,000 wooden electricity poles identified for pole replacement or reinforcement.  Working with EnergySafety, a sampling scheme was designed to physically inspect a sample of wooden poles and compare the results with the database information.  Maps were integral in developing a spatial sampling solution that balanced travel time and inspection time required while delivering an adequate level of assurance.
