The research consisted of a comparison, considering the cost parameter, between the two structural systems most used in Brazil, as well as the presentation of guidelines for the creation of projects in structural masonry, given the lack of knowledge of these techniques by most professional designers. Structural masonry and reinforced concrete projects were developed for two different architectures, one for a residential building and one for a commercial building. The projects in reinforced concrete were elaborated with the help of the TQS tool, while the projects in structural masonry were elaborated using the presented project guidelines. The projects were budgeted in a simplified way and their costs were compared. The results indicate that for the two architectures, the structural masonry project is more economically advantageous than the reinforced concrete, both in the simple comparison between the costs of the projects of the two constructive systems for the buildings, and in the value obtained for the unit cost of each structural project. It was also verified that the labor cost significantly influences the final cost of execution of the projects in structural masonry and reinforced concrete, being, therefore, an important factor to be considered in the choice of the structural system, besides the total cost.
