Eisenbahn Sachverständigenservice OSK
Independent review. Reasoning you can follow.
OSK-Consult investigates and assesses technical facts independently and without a predetermined outcome – after damage and in disputed matters as much as in technical reviews and ahead of major decisions. Findings are reasoned and documented in language a decision-maker can follow.

Your case
What needs assessing?
Choose the area that fits. Scope and approach are then agreed around your specific case.
Failure Investigation & Expert Reports
Damage, its cause or the costs being claimed need to be established.
What you receive
A technical expert report or expert opinion on the agreed questions – with documented findings, an engineering assessment and conclusions you can follow.
Independent Technical Review
Documents, a design or a technical modification need reviewing.
What you receive
A documented technical assessment setting out the scope of review, the findings and the open points, and naming the further assurance evidence required.
Technical Due Diligence & Second Opinion
Before a decision, you need a second opinion on an existing assessment.
What you receive
An independent view of the material at hand: which statements are traceable, which assumptions drive the result, and where clarification is needed.
