NEK 405-3-2 is a new substandard in the NEK 405 series, which describes the methodology and competence for third-party assessment of the delivery to the road owners.

The standard also forms the basis for third-party assessment such as periodic condition analysis.

A third-party assessment will lower the level of conflict in the event of new acquisitions and ensure that requirements in operating and maintenance contracts are met.

Typical clients are road owners such as the Norwegian Public Roads Administration, New Roads, Counties and Municipalities.

The course provides a good competence basis for completing the certification exam.
