Lean Construction: A Quantitative analysis of its application in single-family's residential units in Divinópolis-MG
lean construction, waste management, supply management
In civil construction lean methodology or lean construction, aims to maximize the use of materials and make the most of available labor, avoiding waste production and non-value-added activities. Through lean construction concepts and tools, qualitative results have been observed, such as the use of fewer resources, improved quality, reduced rework, waste, water and energy consumption and lower costs. However, there is a scarcity of studies that quantitatively evaluate the results obtained, allowing their economic categorization. In order to quantitatively evaluate the application results of these concepts and tools, the paper proposes to analyze the indices productivity, the consumption inputs variations and the residues generation resulting from the execution of two identical housing units (the first one executed by conventional management and the second after staff training on lean construction tools). Therefore, its proposes to apply the following lean construction tools: quality management system, adoption of visual resources and last system planner. The productivity, input consumption and waste generation evaluation will involve the following activities: shoring, masonry elevation, structural frame, internal and external roughcast, mortar render finishing, laying of ceramic. Through the paper is expected to obtain quantitative results that enable an quantitative evaluation on the application of lean construction techniques in single-family housing units
