Harbor Bridge Inspection
Project Overview
A Grade I listed suspension bridge requiring its 5-year structural inspection. Traditional rope-access inspection would have required 6 weeks and full lane closures. DroneVision completed the full inspection in 3 days with zero traffic disruption.
The Challenge
The bridge's listed status required non-contact inspection methods. The main span's height and the river's tidal flow created challenging flying conditions, while the steel cable geometry required precise close-proximity navigation.
Our Solution
We used a combination of our long-range inspection drone with 30× optical zoom for standoff inspection and our compact close-proximity platform for cable and soffit access. AI-assisted defect detection processed 14,000 images to flag 47 areas requiring further review.
