Our Areas of Expertise

Utility Drone Inspection Services

Aerial Overhead Line Inspections

  • An inspection of overhead electrical lines using visual images captured by UAS and analyzed by engineers. Results are organized in a prioritized risk assessment report.
Man performing a wood pole inspection, treatment, and reinforcement (ITR)

Wood Pole ITR

  • Wood Pole Inspection, Treatment, and Reinforcement (ITR) program driven by a scientific approach utilizing non-destructive methods that deliver objective insights to optimize remedial maintenance procedures and extend the life of wood assets.
Vegetation Inspection Services

Vegetation Analysis

  • Remote data collection and modeling identifies areas of encroachment, helps calculate volumetrics, analyzes impact on line corridors, and aids in optimizing maintenance schedules.
Infrared (IR) analysis and inspections for energy transmission and distribution industry.

Thermographic Inspections

  • Infrared (IR) imaging identifies overheating equipment and components which are not discernible through visual assessments alone. This service can be performed on transmission, distribution, and substation assets, as well as inside manholes, vaults, and to support special projects/studies.

Underground System Inspections

  • Visual imagery and sensor data remotely collected by UAS/robotics to perform inspections of assets in confined and hazardous spaces, such as inside manholes and vaults.
Overhead electrical lines

Third-Party Attachments

  • Visual inspection imagery is used to perform an inventory of all known and foreign third-party attachments to help audit compliance, collect revenues, and manage joint-use contracts.
