Case Study: a Northeastern U.S. utility strengthens pole reliability with Davey Resource Group inspections

DRG inspects 60,000 poles with Davey using resistograph technology

DRG, a division of Davey Resource Group, Inc., was engaged by a Northeastern U.S. utility to conduct pole inspections across southeastern Pennsylvania. The challenge was to assess the structural integrity of tens of thousands of utility poles to determine which needed reinforcement or replacement, ensuring reliability and compliance with state commission standards.

The solution from Davey involved using a mixture of methods, including resistograph technology, sounding, and visual inspections on 60,000 poles. This identified approximately 3-5% as needing restoration or replacement, which Davey crews addressed with steel reinforcements. The results provided the utility with actionable data for replacements and compliance, leading to a contract extension for Davey through 2023 due to the utility's satisfaction with the technologically advanced approach.
