When a report on road quality, condition or its effect on a collision raises technical doubts.
What we examine
- The complete report
- Diagrams and reports
- Source examination data
Materials to prepare
- Text and appendices
- Questions for the expert
- Design and contract
- Observations on particular findings
Sample questions
- Is the section examined unambiguously defined?
- Is the choice of measurement and sampling locations justified?
- Are the characteristics supported by test reports?
- Were changes after the event examined considered?
- Do the findings follow from the data obtained?
How the work is carried out
- Checking the subject and source data
- Analysis of methods and calculations
- Preparing reasoned comments
Result
A review with specific technical observations and questions for clarification or a new examination.
What affects the conclusions
A review does not recreate absent measurements or produce test reports retrospectively.
Frequently asked questions
Can only the laboratory section be checked?
Yes, where reports, the sampling diagram and records, and material requirements are supplied.
Will a review prove the cause of deterioration?
An independent causal finding sometimes requires further field examinations.
