Acesso em:.https://repositorio.ufpa.br/handle/2011/3538Companies of construction industry in Belem, they are looking for ways to improve their processes and constructive methods through the implementation of the elements and tools of lean production system. The purpose of this work consisted to assess the cases of successes and failure, through of an exploratory study of the implementation of the Lean Production System in construction sites in the city of Belem of Para, to identify which elements and tools of this system are most commonly used in construction of the city in question. This way, an extensive research literature about the subject, showing historical developments since the creation of scientific administration, emphasizing the precursors of production administration and then reporting the emergence of lean production system, as well as their origins and pillars, highlighting its elements and tools. The research methodology used was case study of exploratory character, where the focus was managers that act applying lean production in their construction works. The data was collected through a questionnaire with the classification of questions, closed and multiple choices, consisting of twenty objective questions, in order to generate data to answer the research question. After collecting data were generated tables and graphics for analysis of results. The results analyzed pointed elements and tools lean more used, in addition to presenting the greatest difficulties in the implementation of lean production system, and then was made a correlation between difficulties encountered with the relevant literature. From this, it was concluded that companies are not fully committed with the implementation of improvements (lean production system), so that this demotivates workers and creates resistance to change.porAcesso AbertoAdministração da produçãoSistema Toyota de produçãoConstrução enxutaProduction administrationToyota production systemLean constructionDissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA DE PRODUCAO::GERENCIA DE PRODUCAO::PLANEJAMENTO, PROJETO E CONTROLE DE SISTEMAS DE PRODUCAO
