Bridge & culvert condition assessment
Challenge
Thirty-seven bridges and sixty-two culvert crossings across the county road network required condition documentation for federal-aid eligibility. Traditional bucket-truck inspection was disrupting traffic flow and exposing crews to active roadways.
Solution
IntelAerial deployed high-resolution RGB and thermal infrared payloads across the full corridor over a six-day mission window. Each structure received a georeferenced orthomosaic, thermal anomaly overlay and condition-coded report organized by NBI element.
Deliverables
- Georeferenced orthomosaics per structure
- Thermal anomaly overlays identifying delamination and moisture intrusion
- NBI element-coded condition reports
- GIS-ready layers for county asset management system
Result
Zero road closures required. Inspection timeline reduced from 14 weeks to 11 days. All documentation accepted for federal-aid compliance review.
