SUMMARY:

The lean construction tools aims to rationalize the use of materials and make the most of available labor, avoiding waste and activities that do not add value to the product. However, it is noteworthy the lack of studies that quantitatively evaluate the results obtained by lean construction tools, allowing its statistical or economic categorization. In order to quantitatively evaluate the benefits obtained by the implementation of lean construction tools in single-family residential housing by the execution of certain activities of construction, this work analyzed the productivity indexes, the range in inputs consumption and the residues generation resulting by the execution of two identical housing units (the first executed by traditional metodology and the second after lean construction tools training). Therefore, the following lean construction tools were applied: quality management system, adoption of visual resources and last system planner. The productivity evaluation, inputs consumption and waste generation was carried out on the following activities: forms, masonry elevation, steel frame, internal and external roughcast, internal and external cement plastering, wall and floor cladding laying. Based on the collected data, statistical tests were performed, such as variance analysis and mean difference tests to assess whether there was a statistically significant difference between the activities evaluated. It was observed through data evaluation that the adoption of lean construction tools generated a statistically significant increase in production efficiency for the evaluated activities, presenting like the best results: 51.86% and 42.47% increase in productivity indices for the activities of external roughcast and steel frame, respectively. It is noteworthy that only for the activity of floor cladding laying there was no statistically proven improvement. On the other hand, the lean construction tools adoption helped to reduce the consumption of inputs in activities and there was a reduction of 5.71% in the waste generated volume for the houses construction.
