Hand Over -Cladding free from damage-Facades to be viewed as per the BBA, in daylight from a distance of not less than 10m. Some variation in colour and texture of external walls is inevitable and in certain cases is a feature. A façade for instance should be inspected for scratches or minor imperfections from a distance of min 5m, if a scratch cannot be seen from that distance then it is not a defect except if a scratch has gone through the full depth of the coating exposing the raw metal below.
