COMPARATIVO ECONÔMICO DOS MÉTODOS NÃO DESTRUTIVO X DESTRUTIVO EM ABERTURA DE VALAS PARA INSTALAÇÃO DE TUBULAÇÕES

Abstract

This work presents a comparative analysis between the non-destructive (NDM) and destructive (DM) methods in trenching for the installation of pipes. The research highlights fundamentals such as cost, execution time, safety and social acceptance. The MND stands out for reducing excavations, preserving the soil and reducing disturbances in urban areas, despite requiring greater initial investment and greater technical complexity. On the other hand, DM, widely used in Brazil, has a reduced initial cost, but greater social impact, in addition to requiring a longer execution time. The analysis includes a case study carried out in São João Nepomuceno, MG, which demonstrates the practical differences between the methods. The results indicate that NDM, despite its higher initial cost, offers long-term economic and social advantages, and is recommended for works in densely populated urban areas. It is concluded that the choice of method depends on specific factors of the project, but the adoption of sustainable practices such as MND should be encouraged.
