These are: cover, inherent concrete quality, cracking, surface finishes, honeycombing and surface damage, and dimensional nonconformity. The report incorporates inter alia: flow charts setting out the decision-making process for dealing with the six types of nonconformity; lists of prompts for consideration when carrying out investigations or when selecting appropriate remedies; and typical examples of nonconformities.
