Investigação do uso do princípio enxuto de aumento de transparência para reduzir perdas em obras de infraestrutura que estão em uso durante reformas/ampliação

Abstract

The Brazilian infrastructure is made up of highways, railways, ports, canals, dams, pipelines, power generation plants, transmission lines and communication networks, among others. However, this number is still unsatisfactory and has a lower quality than it could be, characterizing a favorable environment for reforms/expansion in these infrastructure works. However, despite the search for an efficient management model, the principle of transparency contained in the philosophy of lean construction is beneficial for the proper management of these renovations/expansion works in use and the consequent reduction of losses in the process. The objective was to investigate how the principle of increasing transparency can contribute to reducing losses in infrastructure works that are in use during renovations/expansion. The research methodology was exploratory and descriptive with technical visits, evaluation and comparison of three case studies of public works, infrastructure and that were in use during the renovation/expansion. As a result, it was observed that the three works had visual tools in different degrees, in order to vary according to the format of the construction site, which could also be evaluated according to the category of indicators, signs, controls and visual guarantees. It is concluded that the use of the principle of increasing transparency is effective in preventing losses, namely: by movement, transport and waiting. In addition, effective visual tools in a renovation are those whose characteristics are in accordance with the desired function, place of use (dynamic or static) and public served (internal and external).
