The construction sector is important for the development of a country and currently contributes greatly to the economy and employability. Different problems arise in construction projects that put their success at risk. Among the most frequent are partial delays in the execution of works. In our case study, 21,32% overruns were recorded in the final delivery of a project. When analyzing the problem, the main causes were found, being work stoppages by suppliers, reprocessing of activities and discrepancies between the technical file and what was found on site. All these causes have been caused by contractor companies executing the work and the company hired to prepare the technical file, making it necessary to analyze the hiring process of these companies and the process from supervision (which our case study does not present). The use of the BPMN tool is proposed to find necessary processes that the company does not currently manage or to find points of improvement in the current processes and from this model two processes, one for effective contracting and the other for supervision. The PERT tool is proposed to identify critical providers. Finally, the ISM tool is used to adequately rank supplier contracting requirements. It was validated through the reliability of the contractors who executed a project in Cusco, which was 79.12%, implementing the proposed improvement processes this would increase by 9.33% the confidence that the executing companies comply with the planned time, thus reducing economic losses.
