Infrastructure assets — bridges, tunnels, marine structures, retaining walls — are typically exposed to aggressive environments and sustained loading. SiteOps provides the non-destructive investigation data that asset managers need for condition-based maintenance planning and capital expenditure prioritisation.
Bridge deck assessment combines GPR coverage mapping of rebar depth and delamination, half-cell potential mapping for corrosion probability, chloride profiling for durability modelling, and targeted coring for strength verification. This integrated approach identifies the specific zones requiring attention rather than applying blanket maintenance.
For marine and coastal infrastructure, SiteOps deploys ultrasonic thickness testing for steel section loss, chloride profiling for concrete durability, and structural monitoring for ongoing condition tracking. Our evidence-based approach has enabled councils and asset owners to target maintenance funding to areas of greatest need.
Typical challenges
- Aggressive marine and coastal exposure environments
- Traffic management during bridge investigation
- Underwater and tidal zone access constraints
- Long-term durability and remaining service life assessment
- Corrosion mapping across large structural areas
- Asset management planning and capital prioritisation
