This document describes a method to assess the physical condition of all types of immobile constructed assets in a uniform and objective way. The assessment results in a condition class, which expresses the technical state of maintenance of an asset at any certain moment in time on a six-point scale. It therefore can represent either the deterioration of an asset or part thereof or the physical condition at the time of commissioning. By repeating the assessment at regular intervals, it is possible to monitor the degradation of the asset over time.

This document offers a uniform, objective and reproducible method with traceable results. It describes how to achieve the condition class, based on non-destructive observation of defects off any asset or part thereof by using a predefined breakdown structure. The appropriate breakdown structure of an asset is dependent upon the asset concerned and guidance for defining a uniform breakdown structure is given in Annex C.

This document as part of an Asset Management plan can be applied to:

  1. evaluate the actual physical condition of a single asset or portfolio of assets;

  2. establish a maintenance strategy based on the actual condition of the assets;

  3. support financial planning;

  4. encourage and support communication about the actual condition versus the desired condition.
