The book offers insight into the archive of “condition surveys” (Zustandsaufnahmen) created over several years by photographer David Küenzi on behalf of the city of Zürich. The debt-collection and bailiff's office of Zürich 6 produces an officially certified report on behalf of the owner or builder of a property when something is converted, renovated or demolished or a new building arises. The report contains a survey of existing damage (cracks, spalling, etc.) consisting of a written crack protocol and a photographic documentation; the office is obliged to work with freelance, qualified photographers. Küenzi's documentations of the most varied cracks are now relocated in the form of an artist's book. What was once a purely functional document develops, as an autonomous image, an abysmal beauty — at times recalling abstract paintings, at times unsettling.
