RESUMO :  A Lean Construction e uma filosofia que vem crescendo nos diversos meios de construcao do Brasil e do mundo. Apesar de a maioria das empresas construtoras ainda estarem em processo inicial de implementacao dessas praticas e ferramentas, e fundamental que sejam elaborados mecanismos eficazes na avaliacao desse processo, como e o caso do Lean Construction Assessment Tool (LCAT) . Esse metodo de avaliacao e utilizado nesse trabalho para avaliar o grau de implementacao enxuta em seis empresas construtoras em Goiânia. A partir dos dados obtidos, foi realizado o calculo do grau de implementacao Lean utilizando medias aritmeticas, medias ponderadas por especialistas e medias baseadas no Sistema de Inferencia Fuzzy . O trabalho tem como objetivo principal analisar os resultados advindos do diagnostico Lean da aplicacao da ferramenta, avaliando as potencialidades de cada media utilizada. Busca-se ainda avaliar o processo de gestao da producao das empresas pesquisadas, destacando falhas no sistema e como esse poderia ser melhorado. As medias obtidas apresentaram pequenas variacoes, como rapidez de obtencao, interferencia de outras variaveis no processo e analise de especialistas, sendo possivel concluir sobre as diferentes potencialidades no emprego de cada uma. A partir desse estudo foi possivel estabelecer um diagnostico a partir da interacao entre meio academica e ambiente profissional. ABSTRACT : The Lean Construction is a filosofy which is growing in the diverse communication’s means in Brazil and around the world. Although most of the construction companies are in the initial stage of these practices and tools implementation, the development of efficient mechanisms to evaluate this process is vital, such as the Lean Construction Assessment Tool (LCAT). This evaluation method is utilized in this research to evaluate the lean implementation stage in six construction companies in Goiânia. From the obtained data, the lean implementation stage was calculated using arithmetic averages, weighted averages and averages based in the Fuzzy Inference System. This work has as main goal to analyze the results from the Lean Diagnosis obtained using the tool and evaluate the potentialities that each average owns. It’s also a goal to evaluate the management process in the studied companies, highlighting failures in the system and how they can be improved. The averages obtained present small variations, such as speed of procurement, other variables interferences and the specialists’ analysis, being possible to conclude about different potentialities in each’s use. From this study, it was possible to establish a diagnosis based in the interaction between the academic and professional environment.
