The constructional method in structural masonry is increasingly becoming an ideal form for constructions in Brazil, so that its constructional method happens more quickly and generally obtains a reduced cost than the conventional method in reinforced concrete. This is explained by the fact that its execution phase is more simplified, however, need a special initial attention, and the constructive material needs great care in order to reduce waste and possible unnecessary losses, thus collaborating with the economic and environmental items that are important in every work. Therefore, the present research seeks to analyze the technical and constructive aspects, as well as the use of materials, in order to perform a detailed analysis of economic differentials in a two-floor work in two different construction methods, which would be a structural masonry with blocks ceramic and other in reinforced concrete. A bibliographic research was carried out. In addition, visits were made to the work and a visual observation of the applied methods, case study with photographic information, in a quantitative approach, in a comparative study of descriptive level. The diagnosis of the results shows that the structural masonry has a slight advantage due to a faster production, compared to the time proposed for the work, because while in the reinforced concrete it is indispensable to lift the frames, which would be the structures between beam and pillars for after the closing stages, hydro and electric, in the structural masonry with ceramic blocks, these steps are carried out simultaneously. In terms of finishing, structural masonry also overlaps with the fact that it allows a more precise finish, avoiding waste and reducing the total value of the work. In this way, it is concluded that the structural masonry of ceramic blocks entails and significant constructive and operational advantages, in similarity to the constructive method in reinforced concrete, nevertheless, the constructive method of structural masonry still has insufficiencies that only the reinforced concrete could supply, starting from this assumption in some situations only the reinforced concrete would be viable.
