In every construction project there are a high number of criteria and factors, the combination of them should always be performed aimed to fulfil the desired requirements; which criteria and how to evaluate them, that’s the main core of the project development. However the criteria selection and evaluation process is a result of a decision analysis problem, therefore every decision taken requires systematic and defined evaluation methods. Human being take decisions all the time, though it is difficult for us to explain how our intern decision analysis procedure works, this mainly because it is so efficient besides fast that we don’t even realize how we evaluate and weight criteria. However when we are confronted with decisions using a high number of criteria, our intern decision analysis procedure is deficient; according to Miller we cannot achieve a reliable decision when more than 7 +/- 2 criteria are involved1. Thus it is imperative to implement a systematic aimed to secure a liable decision in every construction project. The decision analysis methods are mathematical procedures that make it possible to analyse and evaluate alternatives, based in a high number of requirements and goals in a quantitative form; they also permit it to introduce a systematic to de decision process and make possible to review the decision in a quantitative way at any moment. Besides they also permit the elaboration of global assessment procedures, in which all required criteria are simultaneously evaluated regardless of their units. Another topic is the use of risk management in construction projects. This field is concentrated in the analysis of fluctuations in all variables and finally the way they influence a desired goal and the corresponding probabilities of success together with the procedure of how to abet them. Nevertheless risk management is no new field in the construction industry, however the recent events of global crisis in 2008 have shown, that the way in which risk analysis has been performed, is not reliable and requires new conceptions. In the project development, risk management and especially its sub process “risk analysis” is gaining in importance in order to provide more certainty to the construction projects. The main Target of this work is the utilization of decision analysis to make possible the inclusion of risk analysis as a criterion in project management.    «
