Documentation for the preservation of evidence serves to record the condition before the start of work, including existing damage or defects as well as damage or defects arising from or expected to arise from the execution of the measure.
A procedure for the preservation of evidence thus documents the current condition in the form of an expert report. Should the condition subsequently change, evidence of the condition at the time of the preservation of evidence is recorded.
For example, when do you need an expert opinion on the preservation of evidence:
- If you need to prove that a device or machine has defects
- If you want to prove the current conditions of the machine or plant, because the structural condition of the machine or system is to be changed
An expert opinion on the preservation of evidence can also be commissioned in the context of judicial proceedings
In many areas an independent and objective assessment of plant and facts is often necessary:
- Contractual differences of opinion due to poor performance of services
- Checking of a service for professional, functional and tender-compliant execution
The actual situation is recorded by the technical expert, compared with the contractual performance or with the tender and evaluated.
The result of the inspection then serves as the basis for the further decision-making process.
For the settlement of claims,
- first the actual state is recorded as a basis,
- subsequently the cause of the damage must be determined and
- finally, the cost of restoration and any further measures should be determined.
The technical expertise gives a clear and concise overview of all relevant points, so that a correct damage regulation can take place.
