Bridge And Transport Infrastructure Corrosion Inspection

Bridge and transport assets are exposed to weather, de-icing salts, vibration, access constraints, and long maintenance cycles. A structured corrosion inspection programme helps asset owners prioritise repairs before coating breakdown becomes structural risk.

Assets We Inspect

Typical assets include steel bridges, pedestrian bridges, gantries, parapets, rail structures, coastal transport links, and hard-to-access supporting steelwork.

Inspection scopes can combine visual coating assessment, corrosion mapping, ultrasonic thickness readings, paint inspection, and specialist access planning.

Common Risks

Transport structures often show localised corrosion at joints, drainage points, bolted connections, bearings, splash zones, and areas where coating systems have been damaged by impact or poor access.

Early survey work gives owners a defensible basis for maintenance budgets, warranty discussions, and repair specifications.

Recommended Approach

Start with a coating condition survey to identify visible defects and likely deterioration mechanisms. Use corrosion surveys and NDT where section loss, pitting, or hidden corrosion is suspected.

Where access is difficult, IRATA rope access can reduce disruption and avoid large scaffold packages for inspection-only work.

FAQ

Common Questions

When should a bridge coating survey be carried out?

A survey is useful before planned maintenance, before repainting, near the end of a coating warranty, after visible coating breakdown, or when asset managers need condition data for budgeting.

Can rope access be used for bridge inspections?

Yes. Rope access is often suitable for difficult inspection points where scaffold, MEWPs, or lane closures would be disproportionate.
