Modelo de gestión de procesos con la aplicación de lean construction para el mejoramiento en la ejecución del acápite eléctrico de viviendas residenciales.

Abstract

This degree work was developed with the objective of developing a process management model, applying lean construction tools, on the execution of the electrical section in homes, aimed at improving productivity. In the first instance, a survey was applied to obtain information on the current scenario, regarding process management applying lean construction and productivity. Likewise, the process survey was carried out in the execution of residential electrical installations, this was addressed through the development of four phases (preparation, collection of information, understanding of the process, equipment used and information documents). These data collected made it possible to establish the implementation time, the execution cost and the waste or waste present in the development of the activities. Information that served as the basis for the development of the current situational diagnosis. Finally, a management model was proposed based on value flow mapping, the last planner's system, and waste management through problem solving. The use of the management model applying lean construction allowed graphical representation of the flow of materials from the beginning to delivery to the final customer, it was also possible to identify the activities that generate added value and those that do not, framing them within productive work TP, contributory work TC and non-contributory work TNC. Likewise, the application of the tool the last planner allowed establishing a fast and predictable workflow, evaluating the activities to be developed with a focus on what must be done, what can be done and what will finally be done, analyzing and managing restrictions and evaluating the percentage of compliance. The percentage of non-contributory TNC work was reduced from 32% to 20%, reducing the execution times of electrical installations from 8.76 days to 7.37 days with a projected cost/benefit ratio of 2%. Based on the results obtained, it was concluded that the use of lean construction tools will generate improvements in the construction industry.
