The main objective of this research is to compare the cost and execution time of works to improve vehicular and pedestrian traffic, executed and liquidated by the District Municipality of San Sebastián del Cusco, with the cost and time obtained from the quantitative risk analysis using the PMBOK guide sixth edition, with a reliability level of 90%; in order to verify that with a good risk management the real behavior of a work can be foreseen, therefore, the possibility of proposing response actions that avoid or mitigate the impact of the risks. All the necessary information of 3 Works was collected, this information served as a basis for the identification of risks that affect this type of works, obtaining a total of 43 risks, which were submitted to an expert judgment through the application of a questionnaire. The data obtained from the questionnaires were processed using the “Linear Opinion Combination” method, for which a weight was given to each questionnaire using the “Analytical Hierarchy Process (AHP)” and the Saaty scale, based on the years of experience of each respondent in the different areas responsible as civil engineers. A total of 52 questionnaires were processed, obtaining a preliminary identification risk register with a total of 26 risks defined with the SMART methodology. With the risk register already defined, the qualitative analysis was carried out, for this process it is necessary to determine the probability of occurrence and impact of each risk, the qualitative scales and their scores for probability and impact. Finally, the quantitative analysis was carried out, which requires as input data the types of probability distribution of the impacts of each risk and the use of a risk analysis software, for the case of this investigation the Primavera Risk Analysis software was used. The results obtained detail the variation of the simulation, applying a good risk management practice, without applying answers, with respect to the real executed, obtaining variations in time of 24.6445%, 55.1237% and -13.9053% and in cost of 52.8762%, 53.5957% and 65.7041% for each work respectively.
