A system dynamic modelling approach for integrated lean-BIM planning and control methods

Traditional planning and control methods do not accurately reflect the construction reality and lack feedback loops. The Last Planner System (LPS) and Location-based Management System (LBMS) have been suggested as socio-technical systems to generate practical and actionable real-life data based on production theories and logic. This data can be effectively communicated, analysed, and managed using the capabilities offered by Building Information Modelling (BIM) workflows. However, a true integration between Lean Construction-BIM is not yet matured, where parallel use of both concepts is still more common. This paper presents a conceptual framework based on a system dynamic modelling approach to elaborate a causal loop diagram (CLD). The CLD explores the interactions between basic management functions and waste, on this basis this paper proposes how the integration between LPS, LBMS, and BIM can be harnessed to apply waste elimination strategies. The results of this study can be applied as lean policy analysis for new lean adaptors to understand the impact of Lean-BIM for planning and controlling various wastes across the construction supply chainThis work is funded by National Funds through the FCT - Fundação para a Ciência e Tecnologia, I.P., under the scope of the project 2021.04751.B

Mobile application for collaborative scheduling and monitoring of construction works according to lean construction methods

In the construction industry, an efficient management of information flow as well as enhanced communication and collaboration among stakeholders are crucial to improve construction process management. Construction processes are still managed by means of paper-based documents, e.g. scheduling. To ensure on-time delivery of projects and automate construction management, especially scheduling and monitoring process, a mobile application based on Lean Construction methods is being developed within the ACCPET project. This application aims to improve productivity, collaboration between project participants as well to provide tailored information to the user. To reach this goal the following methods and technologies have been adopted: Location-based Management System, Last Planner System, Tiered Structure methodology and Building Information Modelling. This paper describes concept, framework and functionalities of this mobile application

Metodología lean construction y su incidencia en la ejecución de proyectos de una empresa constructora, Huánuco 2022

La presente investigación sostuvo como finalidad, determinar la incidencia al aplicar metodología Lean Construction en la ejecución de proyectos de una empresa constructora, Huánuco 2022. Por ende, se consideró un enfoque cuantitativo, empleando una investigación de tipo aplicada, de diseño no experimental y un nivel correlacional causal. La población está conformada de 90 trabajadores y se consideró como muestra a 73 trabajadores de la empresa constructora, se utilizó un muestreo probabilístico. La técnica para la recolección de datos se empleó una encuesta realizada a cada trabajador por medio de un cuestionario como instrumento obteniendo la información requerida. Los resultados obtenidos al aplicar el programa SPSS arrojo un nivel de significancia de 0,000 menor al valor de 0,050 y una incidencia del 79,3%, concluyendo que la metodología Lean Construction incide considerablemente en la ejecución de proyectos de una empresa constructora, por medio de una correlación efectiva
