Inspection of structures in service is generally recognised as being necessary to contribute to assurance of safety and to provide a basis for decisions on maintenance and repair. Over the years, in the 12 reports which have appeared since 1977, SCOSS has drawn attention to structures where the current level of inspections appears to be insufficient to identify emerging unsafe situations, or where there is a particular inspection difficulty. The list of topics is long, with some, such as cladding, appearing in five reports, post-tensioned structures of various types in four. Stadia and multi-storey car parks have also given rise to concern in several reports.
