Abstract

This research focuses on the use of concepts and tools of Lean Thinking seeking the implementation of continuous flow in construction. An exploratory case research approach was used in the work. Such study was carried out in a construction site of a resort in the northeast region of Brazil. Taking as a basis literature and successful implementation path used in other industries, a combined analysis was used, first in value stream level and second in processes level. As result of this research, Value Stream Maps (VSM) of the execution of the standard apartment was drawn for a sample of services, including dry wall and ceramic tiling. The maps made possible an organized discussion about the applicability of important lean concepts, such as: takt time, cell production, etc. Line of Balance, Operator Balance Charts and Standardized Work Combination Table were analysed to improve flow.As conclusion,the path of implementation suggested in lean literature and used in several other industries presented interesting potential considering this case study and encourages future studies using and detailing this approach.
