This study analyzed the methods of sizing and execution of precast corbels adopted by two companies located in Southwestern Paraná. The study sought to identify discrepancies between empirical practices and methods that follow standards and recommendations from the literature. The research combined theoretical and practical analysis, highlighting that Company A uses an empirical sizing method, resulting in a higher steel rate than necessary, as demonstrated by calculations based on the methods of Company B (according standards). Although the planned experimental tests were not completed due to technical failures in the equipment, it was possible to perform a comparative analysis between some characteristics or criteria. This analysis revealed substantial differences in the detailing of the reinforcement, control of concrete resistance and compliance with the recommendations. The results show that practices based solely on experience can lead to material waste, while rigorous design methods promote greater structural and economic efficiency. Despite the limitations faced, the work highlighted the importance of adaptation in academic studies, providing valuable subsidies for the improvement of construction techniques and planning in the execution of precast structures.
