Based on the principles of lean thinking, originated from the automobile industry, which seek to eliminate waste, practice continuous improvement and add value to the product from the perspective of the customer, some adaptations have been made to apply the philosophy of lean production in construction. Thus, this paper aims to propose improvements in the concrete placing process using Value Stream Mapping. Therefore, the research strategy adopted was the exploratory case study. The results suggest that the columns concreting process lead time could be potentially reduced from five hours and nineteen minutes to two hours and four minutes.
