Routine underwater structural inspection
Municipal and federal inspection guidelines require regular condition assessments — the underwater section is historically the weakest part of the documentation.

Authorities & Municipalities
Audit-grade ROV underwater diagnostics for municipal and federal structural inspection. Structured findings reports that flow directly into inspection files, administrative records and expert opinions — without media breaks.
For whom
Bridge inspectors, municipal structural inspection offices, road maintenance, waterway administration, water supervision, municipal hydraulic operations and specialist authorities with infrastructure responsibility.
Typical Problem Contexts
Administration-ready documentation
A diver's verbal statement is no longer sufficient. Inspection files, expert reports and funding applications need structured evidence that remains traceable years later.
Comparability over time
Without reproducible methodology there is no reliable statement about change. Municipalities need time series, not isolated single findings.
Flood and event aftermath documentation
After extraordinary loads the condition must be recorded quickly, safely and without additional personnel risk — often with operations still running in the surroundings.
Funding-ready documentation
Many measures are financed through grants. Documentation must match the requirements of the funding body.
Matching ScanSustain Services
Most authority assignments combine ROV inspection with a monitoring programme — that produces the time series inspection guidelines demand.
Typical Workflow
- Alignment with the reviewing authority
Format, depth and focus of the report are agreed in advance with the responsible authority or expert, so the output can be used without rework. - Planning around operations
Closures, traffic restrictions and permits are accounted for. ROV inspection typically runs without operational downtime. - Execution with documented route
Systematic traversal of the planned route. Every finding is captured with timestamp and coordinate. - Processing in administrative format
Structured findings report with image references and action recommendations — ready for the inspection file. - Handover and time-series reference
Method protocol and reproducibility memo are archived so the next inspection can connect as a time series.
Typical Deliverables
- Structured findings report in administration-ready format
- Image and video dataset with time and position reference
- Damage classification according to agreed schema
- Action recommendations for maintenance or restoration planning
- Method and reproducibility memo for follow-up inspections
- On request: executive summary for committee or funding documents
Benefits for the Client
- Inspection-guideline compliant documentation without media breaks
- Comparable time series instead of isolated findings
- Reduced personnel and safety burden compared to diver deployment
- Clear data basis for funding applications, tenders and expert opinions
- Legally defensible findings basis for the responsible body
- Prepared integration with existing inspection and asset management systems
Typical Scenario
A municipal road authority discovers during a routine bridge inspection that the underwater section of a pier is not properly documented. A diver deployment would mean two days of closure. Instead, an ROV inspection with defined routing is commissioned. Result within three working days: structured findings report with image references, damage classification and action recommendations — plus a reproducibility memo that secures the follow-up inspection three years later.
Frequently Asked Questions
Do the reports meet our inspection guideline requirements?
We agree format and structure with the reviewing body in advance. Common municipal and federal structural inspection guidelines are covered so the report can be filed without rework.
Does the bridge or structure need to be closed for the inspection?
Usually not. ROV inspections are performed during ongoing operations. Neither road traffic nor shipping need to be interrupted.
How long does documentation preparation take?
Depending on scope, 2–5 working days. Raw data is available immediately after the mission; the structured report follows shortly after.
Is the methodology procurement-compliant?
Yes. On request we supply a neutral performance description that can be used as the basis for public tenders.
Can the inspection be converted into a multi-year monitoring programme?
Yes, and this is typically the best path. The first inspection defines the baseline; every follow-up produces a delta comparison against the previous year.
