Gestão de custos na retomada de obras inacabadas com aplicação da Metodologia BIM: estudo de caso de uma escola pública

Abstract

BIM (Building Information Modeling) is a methodology that integrates processes, policies, and technology to manage construction information throughout the entire life cycle of a built asset. By digitally modeling both what has already been completed and what is yet to come, BIM provides an accurate view of the remaining stages, facilitating planning and execution. In public works, where deadlines and budgets are limited, BIM helps prevent errors, conserve resources, and ensure that each phase of the project aligns with the schedule, resulting in greater efficiency and speed. In this context, this study aims to apply agile tools for managing 3D modeling, quantity takeoff, and cost estimation in an unfinished public school project. The 3D modeling process includes the following activities: on-site surveys of completed and pending tasks based on existing project documentation, BIM as-built modeling of the school, extraction of quantities from the model, and an updated cost estimation. Through BIM modeling, it was possible to analyze, using filters, what had already been built and what was yet to be constructed separately, allowing for the automatic extraction of material quantities. As a result, essential 3D BIM models were obtained to generate an updated budget, reflecting only the materials required for the project's completion. This study concludes that the use of BIM methodology is a strategic and efficient resource for resuming stalled public construction projects.
