A condition survey involves the examination and photographic recording of an object, surface, or building prior to treatment.

A condition survey aims to:

• Record the present condition of the object, highlighting areas of failure or concern.

• Better understand the nature, history, technology and significance of the object

• Investigate previous interventions.

• Identify causes of historic and ongoing deterioration.

• Present conservation recommendations based on the results of the survey.

• Provide an estimate for works, if required

Techniques used in a condition survey include:

• A visual examination of the object

• A technical examination of the object using ultraviolet light to detect the presence of varnish, non-original materials, the use of particular paints etc.

• The use of raking light to detect inconsistencies in the surface topography of an object

• A written explanation of the condition of the object

• Digital photography

• The digital annotation of diagrams or photographs to locate areas of failure

Presentation of results:

A bound and illustrated report is provided, in which the findings of the survey are detailed with recommendations for the development of an appropriate strategy to stabilise the object.
