Located on the Ohio River, the Ohio Falls Hydro Station includes two towers built in the 1920s supporting a transmission line crossing the river. Rather than building a new crossing in another location, the utility company plans to reuse these towers. To determine their structural integrity, the utility company engaged Exo to inspect them. Faced with constrained site access and a lack of available existing drawings, Exo needed an integrated modeling solution to model the existing structures and analyze their reusability.

Exo used iTwin Capture to process 250 gigabytes of drone-captured photos into a reality mesh model. By then creating a digital twin of the towers and power line, the team could virtually access and measure degrees of corrosion. Based on the digital twin, they evaluated structural loads to identify the appropriate remediation solution to ensure structural stability and determine an estimated life extension of the towers. The virtual assessment saved the utility company a potential 10 years of permitting delays and approximately 80 million dollars building a new tower crossing.
