0 ALERT level A = Most likely a serious problem - resolve or explain 2 ALERT level B = A potentially serious problem, consider carefully 14 ALERT level C = Check. Ensure it is not caused by an omission or oversight 19 ALERT level G = General information/check it is not something unexpected 8 ALERT type 1 CIF construction/syntax error, inconsistent or missing data 7 ALERT type 2 Indicator that the structure model may be wrong or deficient 7 ALERT type 3 Indicator that the structure quality may be low 10 ALERT type 4 Improvement, methodology, query or suggestion 3 ALERT type 5 Informative message, check
