Studies considering the impacts of implementing the Lean Office in a supply sector are of high importance for construction companies, because such companies depend on the consolidation of their businesses and efficient management strategies; they also depend on suppliers of materials and services external to their organization. Thus, the use of Lean Office as a management tool gives construction companies a competitive edge in the present market situation. The purpose of this research is to apply Lean Office tools in a construction company - supply sector, evaluating the impacts in the sector after this implementation. The method used in this work was the case study research. A small construction company contributed with information required by this study. Initially, a description of the business is done with the preliminary design of the supply sector; from this, the current state value stream map is prepared. Then, the value stream map is created for the future state, applying the improvements identified while studying the company. The results led to the identification of faults and opportunities for management improvements. Action plans (Kaizen plans) were prepared aiming for the improvement of the production processes. This research is restricted to a specific company in the industry. One of the researchers is part of the company's staff and had access to information needed for the study. This work aims to contribute spreading the use of lean tools to improve the management of companies, regardless of size. After applying the kaizen plans in the supply sector, new indicators, such as cycle times, lead time and added value, were checked and compared to the previous state of the company.
