As-Built Documentation

Ready for audit. Complete. Ready for operation.

At the end of a project, it is not just what was built that counts - but how well it is documented.


With the As-Built Documentation Thor Engineering Services & Expert Office GmbH creates the formal and technical basis for the safe handover, commissioning and further traceability of industrial pipelines and vessel systems. We ensure that all construction-related information – from welds and test reports to material data – is complete, structured and ready for use.

Our documentation meets the highest requirements and can be integrated into existing operator or QA systems - digital, ready for audit and traceable.
