Once the range of factors that may influence the overall stability of a building is great, the brazilian codes and commercial computer programs become more complex as well as the methods of analysis and design. The constructive effect seeks to bring the reality of a building in construction closer to the designer’s calculation, taking into account all the steps of the design’s constrution. In this way, the constructive effect will consider not only the loadings relative to the own weight, but also all those inherent to the process of construction of buildings. On the other hand, the soil-structure interaction seeks to optimize the prediction of differential settlements, since it does not consider the superstructure and foundation working together, but considers the edification completely and not in parts. In order to analyze effects that may influence the overall stability of the building, this work intends to understand the influence of the constructive effects and the soil-structure interaction, through CAD/TQS software. An analysis was performed not only with the parameter z, but also with the parameter α, maximum displacements of the building, and the values provided by CAD/TQS FAVt. To complement the analysis, the loads in the foundations and the settlements suffered by them were evaluated. A symmetric and non-symmetric plant was also analyzed. For this, the models were processed in light of the usual calculation of the z method, with variations of criteria provided by the software itself. The results showed that the constructive effect used alone did not show relevant results. For soil-structure interaction, the variations are more visible. The ideal case, joining the incremental effect and the soil-structure interaction, provides results in agreement with the literature and presents the highest values, thus showing the importance of the tools.
