The positive situation currently experienced by building industry, towards to an industrialization and rationalization, is the result of various new technologies of production and management emerged in the 90s, in order to enhance the competitiveness of firms, increase the flexibility in the final products and improve the quality of these. One of these philosophies, specifically the one is against waste and seeks to add value to the product by understanding needs of the final customer, is known as lean construction. In accord to this, the objective of this study is to propose, through a case study in C. Rolim Engenharia Ltda. (Brazilian building company), guidelines for internal evaluations at the construction site about the level of application, implementation and consolidation of this philosophy in a company that already has embedded in its organizational culture. The methodology for the development of this proposal includes: characterization of the company which will be evaluated in this case study; formulation of the lean tool checklist according to lean practice of the company; and the definition of the application parameters, such as frequency and evaluation criteria. For this case study, the lean audits were applied monthly, from June 2011 to October 2011. These, in fact, point out to reach the goals set, once: all audits have attended more than 80% of the lean checklist requirements, and performance and areas for improvement in the lean aspect are reported on the Lean Diagnosis generated from the Lean Checklist, besides the fact that the audits and their Lean Diagnoses impact positively the process of making strategic and tactical decisions in the construction site.
