This article makes a comparative analysis of ribbed slabs and steel deck type, in works in the city of Manaus. The study was built from the comparative analysis method that seeks a causal inference, trying to define a comparative systematic illustration, that is, it seeks to verify the main attributes of a model and to compare it to another model by checking the advantages and disadvantages of one or the other. The choice of the theme was therefore motivated by the comparative analysis of the following points: the demand for more work in relation to the issue of slab production and execution; the ambiguity surrounding the discussions and proposals on the predominantly regional theme; and the need to evaluate the production and execution of the two (2) types of slabs (ribbed and steel deck type). the steel deck slabs have a lower cost than the ribbed slabs, corresponding to a 20.0% difference. However, for spans greater than 6.0 m, the relative cost of the steel deck slab increases significantly, reaching a difference of more than 70%.
