This document describes general requirements and procedures for the assessment of concrete structures.


The assessment can be initiated under the following circumstances, but not limited to:


a)       an anticipated change in use or extension of design service life;


b)       structural deterioration due to time-dependent actions such as corrosion of reinforcement, fatigue, etc.;


c)        safety and/or serviceability check (e.g. for earthquake and increased traffic actions) as required by authorities, insurance companies, owners, etc.;


d)       structural damage by accidental actions (see ISO 2394).
