Resumen
Las actuales investigaciones de Lean Construction y Building Information Modeling (BIM)
se han centrado principalmente en los aspectos teóricos relacionados con su integración
y sinergia. Sin embargo, poca atención se ha prestado al desarrollo de métodos prácticos
Lean-BIM para gestionar proyectos y proporcionar evidencia de las oportunidades de
mejora de rendimientos. En esta investigación, se pretende llenar este vacío mediante la
propuesta de un marco de planificación Lean-BIM mediante la integración de Last Planner
System (LPS) y BIM.
El desarrollo de la investigación para probar el concepto de un marco de planificación
Lean-BIM se lleva a cabo mediante la comparación de 2 casos de estudio: uno usando
sólo LPS y otro usando LPS y BIM. Se realiza un seguimiento a la etapa de obra gruesa
de ambos proyectos como parte del equipo de oficina técnica de la obra.
Se reúnen datos de ambos proyectos, se analizan y comparan los procesos de
planificación. Dentro de los datos obtenidos se incluyen: dinámica de las reuniones de
Planificación Intermedia y Semanal (número de participantes, roles, duración promedio
de cada reunión y horas hombres asociadas), indicadores de LPS y Requerimientos de
Información (RDI).
Posteriormente, se utilizan mapas de proceso (diagramas de flujo) para documentar
ambos procesos de planificación y la propuesta mejorada de planificación. Además, se
integran las diferentes etapas de la planificación. Los resultados demuestran que el uso
coordinado de LPS y BIM genera una reducción de la duración de las reuniones, un
aumento del PAC, una disminución de la variabilidad del PAC, una disminución de las
CNC y una disminución del número total de RDI de diseño.
Se busca generar las bases para futuras investigaciones mediante una propuesta de
planificación mejorada que combine LPS y BIM, y así demostrar que se facilita la
interacción con un número mayor y más diverso de participantes del proyecto. Por otro
lado, que al manipular BIM en las reuniones de planificación, se generan reuniones más
efectivas y como resultado, mejora la comunicación y la confiabilidad de la planificación
del proyecto.
The current research on Lean Construction and Building Information Modeling (BIM) has been focused mainly on the theoretical aspects related to its integration and synergy. But little attention has been paid to the development of Lean-BIM practical methods to manage projects and provide evidence of opportunities of performance improvement. In this investigation, we aim at filling this gap by proposing a Lean-BIM planning framework in which Last Planner System (LPS) is integrated with BIM. The research conducted to develop proof of concept of a Lean-BIM planning framework is carried out by comparing two case studies: one only uses LPS and the other one uses LPS and BIM. We monitor the construction activities related to rough work in this comparable building projects as part of the field office staff. We gather data of both projects. Then we analyze and compare the planning processes. Among the obtained data we included: dynamic of weekly and lookahead planning meetings (number of participants, roles, average duration of each meeting and HH associated), LPS metrics, and design Requests For Information (RFI). Subsequently, we utilize maps of processes (flowcharts) in order to document both planning processes and the improved planning proposal. Furthermore, we integrate the different planning levels. Results show that the coordinated use of LPS and BIM generates a reduction in the duration of meetings, an increase in the PPC, a decrease in the variability of the PPC, a decrease in the CNC, and a decrease in the total number of design RFI. The improved planning proposal combines LPS and BIM and facilitates the interaction of a greater and more diverse number of participants in the project. The utilization of BIM in the planning meetings creates meetings which are more effective, and as a result, the communication and the reliability of the planning of the project improves.
