In this Work is proposed the organization for structural steel supply process in the construction of a commercial building, correlating the supply logistic of the site with the assembly of the steel structures. The proposal was developed using the concepts of business logistic and of the original lean construction conception that was developed by Toyota Production system and later applied in other sections as the one of the building site. In order to emphasize critical problems of the provisioning process of materials and to identify there the main solutions, it was studied a logistic proposal for the supply of the structures in a located work downtown of Rio de Janeiro. The synchronization between the logistics activity and the structures assembly process followed the lean logic of reduction of wait time, of elimination of stocks in construction site, as condition for the improvement of the productivity of construction. It was analyzed the value stream mapping of the materials flow and operations understood between the structures warehouse and the construction site, verifying the swinging of production activities and the possible productivity gains. The obtained results would evidence potential earnings in the measure that it supplies justifications for the application of logistics activities and of the lean tools for structural steel supply. The proposal presented logistic integrates the manufacturers of structures with the work and mainly it reduces the waits and stocks in process, that wastes are considered in lean constructive conception. We can conclude that the logistic is a decisive factor in the viability of any construction process, and that, specifically, under the concepts of lean construction system, it gathers conditions for the improvement of productivity of the constructive process and consequently increase of competitiveness.
