Abstract

The correct way to intervene damage to a building is from the study of the characteristics of the lesions and causes that gave rise to their appearance. For this, it is convenient to have tools in the collection of information, data processing and results analysis. In the industry branch, aeronautics, transport, among others, operational reliability has been developed as a philosophy to improve processes. Within this there are various tools such as the criticality analysis, the method of the impacts and the technique of Pareto, which allow to determine the criticality of a relationship, element or system. For not having evidence that these have been used for constructive evaluations, it was necessary to adjust the terminology, the parameters and their weights. For the validation of the proposed adjustments, the Delphi method where 20 specialists participated were used. In the critical analysis, the levels and indexes of frequency, impact and detectability were established, as well as the fields, attributes and importance for each of them, which will also be used in the Pareto technique for the analysis of the consequences. In the impact method, 16 parameters and their categories for the technical, functional and economic evaluation of the building were defined. These tools allow the evaluation of the systems of a building in an integral way, since the effects of constructive damages are considered functional, sanitary, environmental and economic fields.
