Uso do Kanban na produção de pré-fabricados de concreto

Abstract

In the search for methods capable of fostering significant changes in civil construction, the industrialization of the sector using the prefabricated parts has stood out as an option, fighting delays that reach the construction industry. However, as effective as the method, without adequate planning and control, the production of prefabricated parts can consume resources and compromise the schedule without conferring the expected results. Thus, this work aims to present the results of the analysis of a factory of prefabricated parts considering the relevance of the identification of bottlenecks and improvement of productivity and reliability of the process. The case study was developed in an industry that operates in the metropolitan area of Recife-PE, which although it was planned to produce 3,000 m³ of concrete, is not capable of producing at least half of the expected. In addition, a constant delay of the work put in check its credibility with clients. Thus, the parts manufacturing process was analyzed with the help of kanban. The method proved to be very effective and allowed the identification of bottlenecks in the flow, and through this, the application of corrective actions allowed the increase of approximately 50% in the monthly production of concrete volume and reduction of the delays of works practically in their totality.
