Resumen
En la actualidad existen diversos tipos de mercados que crecen rápidamente y requieren que se construyan nuevos proyectos, uno de este tipo son las estaciones de servicio, que por su envergadura se puede categorizar como obras de corta duración. Analizando dichas obras se puede denotar que se subestima su planificación, y por consecuencia se puede incurrir en problemas que derivan en atrasos. Es por este motivo que la investigación propone el uso del sistema Last Planner System (LPS) para mejorar el seguimiento y control de avance, y la gestión de Requerimientos de Información (RDI), analizando retrospectivamente un proyecto de corta duración del tipo estación de servicio: ENEX Los Domínicos.
En este proyecto los principales problemas que se encontraron son de seguimiento y control de avance, que derivaba en una deficiente anticipación de los posibles problemas. Además en dicho proyecto, el mandante para solucionar una incongruencia entre documentos pide que éstos sean formalizados a través de RDI, por ello la gestión de RDI debe ser eficiente y fluida, lo que no ocurrió en el proyecto, y como consecuencia estuvieron directamente relacionados con el atraso de 3 meses del proyecto.
Con el análisis completado de todos los problemas que ocurrieron con un posterior diagnóstico a través de literatura, se encontraron falencias del proceso de planificación actual. Por ello se propuso el uso de LPS, pero a diferencia de antecedentes bibliográficos, éste se hizo adaptando sus etapas a periodos más acotados, programación de corto plazo de 2 a 3 días de duración y programación de mediano plazo a 2 semanas. Además se propuso que la
ix
emisión de RDI fuera incluido en la programación de mediano plazo, tomando éstos explícitamente como restricciones.
La propuesta fue validada por el gerente de proyectos de la empresa constructora. Posteriormente se validó la propuesta, comparándola con el proceso de planificación actual, a través del Test de Charrette a estudiantes 5to y 6to año de Ingeniería Civil de la Universidad Andrés Bello. Los resultados de dicho Test detallan un mayor entendimiento de la propuesta de implementación de Last Planner con respecto al seguimiento y control de avance, anticipación de problemas y gestión de RDI, por ello esta investigación entrega una propuesta con varias etapas de validación que permite adaptarla a obras de corta duración.
Currently there are various types of markets that are growing rapidly and require that new projects are built, one of this type are filling stations, which by its magnitude can be categorized as short-term works. Analyzing these works can denote that planning is underestimated, and consequently can incur problems arising in arrears. It’s for this reason that research proposes the use of the Last Planner System® (LPS) to improve tracking proyect progress, and management of Request for Information (RFI), retrospectively analyzing a short-term project type filling station: ENEX Los Domínicos. In this project the main problems encountered are tracking project progress, which derived in poor anticipation of possible problems. Also in this project, the owner to resolve an inconsistency between documents asking that they be formalized through RFI, so the management of RFI must be efficient and fluid, which didn’t happen in the project, and as a result were related directly the delay of 3 months of the project. With the completed analysis of all the problems that occurred with a subsequent diagnosis through literature, deficiencies were found in the current planning process. Therefore the use of LPS was proposed, but unlike bibliographic records, this was adapting its more limited periods stages: short-term planning two to three days long and the lookahead planning to 2 weeks long. The proposal also includes the RFI issue in the lookahead planning of LPS, taking the RFI explicitly as constraints. The proposal was validated by the general manager of the contractor company. Subsequently the proposal was validated by comparing it with the xi current planning process, through the Test Charrette to 5th and 6th year students of Civil Engineering at the University Andrés Bello. The results of this Test detailed a greater understanding of the proposed implementing Last Planner with respect to tracking project progress, anticipation of problems and management of RFI issue, so this research gives a proposal with several validation steps that can adapt to short-term works.
