Desarrollo y aplicación de la metodología BIM para la planificación y ejecución de un proyecto inmobiliario en la ciudad de Quito : gestión de costos y colisiones utilizando herramientas BIM.

Abstract

The work developed in this document involves implementing the BIM 5D methodology in the "San Francisco" project to manage and estimate costs across various disciplines: architecture, structure, plumbing, and electrical. Using 3D parametric models in Revit, a detailed cost analysis based on the United Kingdom methodology was incorporated, facilitating a precise representation of each item. The ISO standard established the requirements and guidelines for effective BIM implementation, and AACE's recommended practices guided cost management, ensuring accuracy and reliability. The process included the development of a Work Breakdown Structure (WBS) and a detailed price list, exported from PriMus, presented in the annexes. The price analysis allowed specific items to be assigned to each family of elements, creating integrated 5D models. The comparison between Revit and PriMus-IFC showed minimal variations, confirming the method's accuracy. Federated models created under the IFC protocol integrated all disciplines into a single coordinated model. Through virtual walkthroughs, issues were proactively detected and resolved during the design phase, significantly reducing collisions detected later in Navisworks. The collision analysis, with tolerances adjusted by discipline, highlighted the importance of setting appropriate criteria to avoid minor interferences that do not represent significant costs. Finally, the final budgets for each discipline and the overall project were presented, confirming the viability and precision of the BIM 5D methodology. This integration allowed efficient cost and resource management.
