During a regular inspection, the team learned that a critical 161kV overhead transmission tower had been damaged during a recent flood. This particular line was serving power to several area hospitals that were at full capacity during the pandemic. Loss of power would have been catastrophic to the area. Exo was tasked with conducting a survey of the tower to assess its condition. However, the line needed to remain energized, requiring the team to find a safe but still efficient workflow.

Exo selected Bentely’s iTwin Capture to accurately survey the deflected shape of the structure. Meanwhile, Power Line Systems was used to efficiently model the power lines and latticed steel support structures as a system. The applications allowed Exo to create a digital twin and design a stabilization solution so that the line could remain in service. By using Bentley applications, the team saved four to six weeks in surveying time. Exo saved lives by stabilizing the structure to avoid a potential long power outage during the pandemic.
