Abstract

Precast elements have prominence in Brazilian civil construction in recent years. Because the production of structural parts is industrialized, this segment has provided a product with better quality control and technological performance. In the current economic situation in Brazil, the market has few opportunities, decreasing sales prices, and profits, in addition to constant pressure for more efficient manufacturing. In this approach, many companies choose to use lean construction, looking for an opportunity to maximize the added value of the product for customers, reduce waste, generate quality, and produce in a continuous flow. However, the sector is still characterized by the significant variation in demand, which is a reflection of the market with differences in typology (pieces) requested in the construction. A low standardization of projects, flows, and workloads vary throughout the month, hinders productive stability and the implementation of lean production. The present research adopted the Action Research methodology, proposing to stabilize the production of precast prestressed beams. In the stabilization process, it was possible to identify the impact caused by production variations on basic stability, assuming to propose processes to be improved within this production line.
