Industrial plant reliability appraisal of the general procedures include: a clear identification of the objectives, scope, content; preliminary investigation: the development of identification programs; detailed investigation and testing; reliability analysis and calculation; reliability assessment; appraisal report. In the industrial construction price can be home in the process of actual determination, if found that the investigation and testing information is insufficient or inaccurate, we must promptly carry out additional investigation, testing. For those problems are very obvious and particularly serious, but through the state of analysis and preliminary calibration can make a clear judgment of the project, the actual application of identification procedures can be based on the actual situation and identification of the requirements for appropriate simplification.

Based on the results of the detailed investigation and testing, the reliability level of the building or structure as a whole and of the individual components is analyzed and verified. Reliability analysis and verification includes two important components, one of which is structural analysis, structural or component verification analysis, i.e., analysis of the effects of the structure and analysis of the structural resistance and other properties, as well as verification analysis of the structure or component in two limit states. Another important component is the analysis of the causes and effects of structural problems, such as defects and damage to the structure, to analyze the causes and effects on structural performance.
