Aging Interstate Bridge Network — Accelerated Inspection Cycle

Texas DOT needed to complete NBIS-compliant inspections on 47 aging interstate bridges ahead of a federal funding deadline. Traditional methods would have required 14 weeks, lane closures on major corridors, and significant traffic disruption.

340-Mile Pipeline ROW Survey — Encroachment & Integrity Assessment

Kinder Morgan required a full right-of-way survey of a 340-mile natural gas pipeline corridor following a period of heavy rainfall and flooding. Ground crews would have taken months and faced significant access challenges in remote terrain.

180 MW Solar Installation — Full Thermal Audit & Yield Recovery

NV Energy observed a 6.2% underperformance gap in a 180 MW utility-scale solar installation compared to modeled output. String-level monitoring data was inconclusive, and a panel-by-panel ground inspection of 540,000 panels was cost-prohibitive.

312 Transmission Towers — Eliminating Climber Risk Across Two States

Ameren's annual transmission tower inspection program required 312 structures across Missouri and Illinois. The existing program relied on tower climbers, resulting in 3 near-miss safety incidents the prior year and a 22-week inspection cycle that left structures uninspected for extended periods.

Offshore Wind Farm — Blade Surface Analysis & Leading Edge Assessment

Ørsted needed blade inspections on 84 offshore wind turbines following the first full operational season. Salt spray and high-velocity operation had accelerated leading edge erosion beyond modeled rates, but the remote offshore location made rope-access inspection logistically complex and expensive.
