Estudo de caso: fundação para sobrado residencial na cidade de Pimenta - MG

Foundations are structural elements that transfer loads from a structure to the ground. Various foundation types can be considered for building projects, and selecting the most suitable option requires a comprehensive technical and economic analysis. Factors such as the characteristics of the structure, soil properties, neighboring constructions, cost, execution time, and local technological limitations must all be evaluated. This study presents a case study of foundation design for a two-story residential building located in Pimenta, Minas Gerais, Brazil. Mechanically excavated piles with a helical auger were identified as the most suitable solution, with bearing capacity estimated using two semi-empirical methods: Aoki-Velloso and Décourt-Quaresma. The design process was automated using an electronic spreadsheet, adhering to applicable standards and established technical guidelines. Finally, a comparative analysis between the proposed and the executed solutions — focused on required concrete volume — demonstrated that the suggested alternative demands a smaller quantity.
