It is widely understood and accepted that existing concrete structures are different entities to contemporary new concrete structures. There are numerous flexibilities inherent to the process of the design of new concrete structures and in their construction. Existing structures are entities that can, in principle, be interrogated and assessed to establish their actual nature and condition. However, such processes have their difficulties and uncertainties and it is in fact often very difficult to interrogate an existing structure. These difficulties increase when an existing structure has experienced damage or deterioration. Accordingly, substantial and different uncertainties remain with respect to existing structures and these uncertainties need to be taken into account in the structural assessment process.
