The Andon device is traditionally used in the manufacturing industry. This visual management tool shows the status of operations in an area and signalizes the occurrence of abnormalities. This research work takes the view that its application is connected to lean construction concepts, as its main function is to identify problems within the production line. It becomes possible to determine the origin of the production disturbances during the building process and not only at the end of it, in a way that the required measures can be taken to avoid the repetition of such problems. It is noticed also that the use of Andon improves the continuous flow of the activities and avoids rework. Moreover it provides operative crews and production managers the opportunity of learning. The application of this managerial tool has gained adepts in construction companies in the Brazilian northeast. The objective of this article is to show the steps for the application of this tool within the building construction environment. This work was developed through a case study in a multi-storey building construction and it encompasses hardware installation (both at the work place and management office), development of control charts, and the production problems analyzes. This study is concluded with the presentation of the results acquired with the use of this managerial tool. The number of work stoppages was reduced significantly, communication was greatly enhanced and transparency was enacted as production problems were readily reported, discussed and analysed.
