The design of isolated rectangular foundations is essential in the construction of structures, and given the increasing focus on cost reduction and environmental impact, optimizing these foundations has gained significant relevance in civil engineering. This study addresses the optimization of foundations in frictional, cohesive, and mixed soils using the exhaustive search method, aiming to minimize construction costs. A mathematical model was developed, including critical variables such as foundation depth, initial eccentricity, and rectangularity ratio (B/L). Results indicated that an optimal depth and appropriate B/L ratio can reduce costs by up to 35% compared to conventional methods. Additionally, a sensitivity analysis was conducted to evaluate the influence of various parameters on the final design. The developed methodology not only maximizes economic efficiency but also promotes sustainable practices by reducing the use of construction materials.
