Análise comparativa de custos entre o Radier protendido e Fundação em estaca hélice contínua: um estudo de viabilidade aplicado na construção de um condomínio de padrão popular na região metropolitana de São Luís.

Abstract

For the establishment of a structural system compatible with the demands of the building it is necessary to start a cohesive process of determining and executing the foundations model chosen for the project. However, as it is an important part of the building process, the chosen methodology has a major impact on the construction budget, which, depending on the solution chosen, can lead to ostentatious expenses that imply a possible compromise in the costs of the project. The following work seeks to compare the costs of installing opposite methodologies for implementing a foundation, evaluating the real practical contribution to the situation in question and its economic viability. To this end, the types of costs related to the installation of prestressed radier models, such as direct foundation, and continuous propeller pile, as a deep foundation, were analyzed, where it was possible to observe the ostensible increase in costs in the continuous propeller foundation in relation prestressed radier, within the same model situation.
