Resumo: Currently there are companies in the construction sector which are incorporating lean construction concepts as a strategy in order to improve their production system. However, this transformation process presents several difficulties, particularly among these, the lack of a clear methodology for diagnosing propose and implement improvement. Based on this, the goal of this dissertation is proposing a methodology to diagnose, finding opportunities for improvement and implementing these opportunities in a construction site, based on concepts and techniques (VSM and LOB) of lean production. To achieve this target, firstly, we make a literature review along with expert s interviews. In second place, we made an experimental practice at São Carlos city (São Paulo-Brazil), where we got some guidelines and procedures to implement a lean philosophy. Those procedures were progressing through discussion and feedback of practice and theory, until achieve a methodology, final product of this dissertation. After this, a methodology was applied on a case study at Limeira city (São Paulo - Brazil). Finally, this methodology is structured in four stages: problem identification, classification of root causes, creating proposals for improvement and implementation. Among the conclusions, there is, on the one hand the systematically way of the methodology, embracing topics such as: lean philosophy, lean techniques (VSM and LOB), methods currently used by companies in the lean consulting sector and the method described by Shingo to achieve improvements. In the other hand, the need to define certain variables for each activity (cycle times, lead times, number of workers involved, elements of work), in order to allow the implementation of more refined concepts such as balancing of the production chain, Just in time, streaming, stock disposal etc.
