The use of steel structures has gone considerably up in Brazil over time. However, in some construction sites that use this structural system, the planning phase is omitted. That happens mainly because of the scarcity of models that satisfy all the specific characteristics from the metallic structural systemThe execution of this type of work could be divided into two stages: fabrication and assembly. The first stage has a production system very similar to the one used by the major manufacturing industries. The executive process of the assembly stage has several characteristics in common with the other pre-fabricated systems available in the civil construction industry. Therefore, it is necessary that the execution planning for the ligh steel structures take into account the aspects related to the manufacturing and vicil construction industries. This paper began with the bibliographical review, searching for the main tools used in the manufacturing and construction industries planning. After gaining the necessary theoretical background, it was possible to create planning models, presenting the tools and procedures, following the sequence that is normally used in steel structure construction. . This paper’s main objective is to offer planning models that take into account all the characteristics from this system. With the goal to elaborate and evaluate the applicability of planning models, two case studies were developed. In both studies, application scripts were developed and using the selected planning tools for the bibliographical review, they were applied to real situations. The first case study studied the fabrication stage, using tools from the manufacturing industry, and doing the analysis based on the data gathered in a steel structure factory. The second case study analyzed the assembly stage of a steel structure, applying planning tools from the civil construction related to time. In the first case study, it was possible to reach the following results: knowing the real deadline for the fabrication of the studied construction, obtaining the tools that allowed the reduction of losses, verifying the adequacy of the resource amount and establishing a standard for the executive process. Applying the second case study, it was possible to conclude that it would reduce in 27,5 days the time of assembly, besides obtaining tools that would facilitate the execution control.
