Resumo
The use of tools to analyze the implementation and use of practices and principles of lean construction is extremely necessary for them to be successful and bring the expected results. Therefore, the tool which is going to be used must be adequate and capable of measuring in the best possible way the real state of the construction company against lean philosophy. This research's objective is to develop a tool to evaluate the degree of implementation of the lean construction in building companies. The LCAT (Lean Construction Assessment Tool) has been developed based on other tools previously proposed with the aim of supply the deficiencies presented by them, mainly the absence of statistical treatment and in the fidelity of the results. Using multivariate data analysis techniques, such as hierarchical group analysis, form revisions were performed, which, according to the comparative tests executed, increased their level of replication and applicability. The evaluation form was analyzed by experts, who classified the items as their importance, complexity and time of implementation. The Fuzzy Inference System was utilized in order to reduce the subjectivity and interpretation bias of the evaluator, which generated closer results between two different applicators to the same object of study. As a secondary result, the participating companies of the applications were evaluated towards the implementation of the lean construction. It was noticed that the companies, for the most part, still do not apply lean construction concepts and tools, evidences were found only of the application practices that interfaced with other areas of management, such as quality and planning.
