Mapeamento de fluxo de valor para gerenciamento de projetos de infraestrutura rodoviária

Abstract

This study aims to analyze the application of Value Stream Mapping (VSM) in the management of highway infrastructure projects. The research was conducted as a case study based on the author’s professional experience, using technical documents as data sources, including the current process flowchart and the project’s client interaction history. The methodology enabled the mapping of the current development flow, identification of bottlenecks, rework, and non-value-adding activities, and the proposal of a new workflow aligned with Lean Thinking principles. The study highlighted the dependence on the Topography and Geometry disciplines, which serve as the foundation for subsequent project phases. One of the main issues identified was the instability of the Geometry project, which led to frequent revisions and cascading impacts. As a solution, the implementation of the Technical Analysis Report (RAT) was proposed, a tool designed to formalize technical assumptions, record client feedback, and standardize the validation process. The results demonstrated improvements in traceability, predictability, and reduction of rework. VSM proved to be an effective tool for diagnosing and improving project management, contributing to process standardization, better resource utilization, and greater clarity in technical validation stages. It is recommended that the proposed methodology be applied to real projects, with quantitative data, to evaluate the actual gains and potential for replication in other construction industry contexts.
