Resumen
El presente trabajo emplea una propuesta que contempla la implementación de la metodología Last Planner System para la ejecución del proyecto; “construcción de la estructura de control de mareas del ramal A del estero salado”; ubicado en la ciudad de Guayaquil. La metodología propuesta contempla a detalle la ejecución de los principios fundamentales de Lean Cosntruction, haciendo énfasis en la aplicación de varios métodos de planificación y control de proyectos, partiendo del desarrollo de un Plan Maestro o también denominado Master Plan que será el esquema principal para la implementación de todos los principios de la metodología Lean. El cual contempla además la determinación de la ruta crítica del proyecto y la secuencia lógica de las actividades. Este sistema implica realizar una adecuada planificación y programación; tanto mensual, semanal y diaria o también denominada Look Ahead Planning, la cual presentará a detalle todas las actividades a realizarse en el transcurso de la semana, llevando un control de la ejecución real vs lo planificado; en este sistema de planificación se realizará un tablero que mostrará el detalle de todas las restricciones que existieren en el proyecto y será el encargado de llevar el control para que dichas restricciones sean liberadas antes del tiempo planificado para la actividad; además se mostrará el detalle y el seguimiento para la liberación de cada restricción. Para evaluar el cumplimiento de la aplicación de la metodología se propone realizar formatos de control que midan el Porcentaje de No cumplimiento (PAC) Y Razones de No Cumplimiento (RNC) de las actividades planificadas, los cuales permitirán conocer los porcentajes de cumplimientos reales en obra; Para complementar todo lo descrito anteriormente se proponer realizar una gerencia visual que nos permitirá tener una visión general del desarrollo del proyecto, la cual estará enlazada en el análisis de la evaluación y medición de la producción vs gastos, o también denominado valor ganado el cual nos dará un perspectiva no solo del rendimiento sino también progreso económico del proyecto.
The present work uses a proposal that contemplates the implementation of the methodology Last planner System for the execution of the project; “Construction of the tidal control structure of the A branch of the salty estuary; located in the city of Guayaquil; The proposed methodology contemplates a detailed implementation of the fundamental principles of Lean Cosntruction, emphasizing the application of various planning and project control methods, based on the development of a Master Plan or also called the Master Plan that will be the main scheme for the implementation of all the principles of the Lean methodology. Which also includes the determination of the critical path of the project and the logical sequence of the activities. This system implies proper planning and programming; both monthly, weekly and daily or also called Advance Planning, which will present a detail of all the activities during the week, the control of the actual execution against the planned one; In this planning system a board will be executed that will move the detail of all the restrictions that exist in the project and will be in charge of carrying out the control so that restrictions are released before the planned time for the activity; In addition, the detail and monitoring for the release of each restriction was carried out. To evaluate compliance with the application of the methodology, it is proposed to carry out control formats that measure the Percentage of Non-Compliance (PAC) and Reasons for Non-Compliance (RNC) of the planned activities, whatever the percentages of actual compliance on site are. ; To complement everything described above, it will be proposed to carry out a visual management that allows us to have an overview of the development of the project, which will be linked in the analysis of the evaluation and the measurement of the production vs. expenses, or also the value earned which gave us a perspective not only of performance but also economic progress of the project.
