Abstract:

This study presents an analysis of methodologies to improve productivity, based on the Lean Construction philosophy (Construction without losses), 3 methodologies were applied to the construction of an urbanization, first a Survey of detection of work losses, which is carried out to identify sources of losses and frequencies that occur within the work; second a Survey of detections and delays to identify the sources of interruptions of greater frequency and to quantify their times during the working day; and third, the Resource Balance Chart, which is applied on the field to the construction crews, with the objective of analyzing the efficiency of the construction methodology used. The activities chosen to carry out the analysis of the third methodology are: Wall Masonry, Facade Plastering and Floor Tiles; these items directly affect the construction project, since these activities together represent approximately 50% of the total budget allocated to finishings; that is, almost 20% of the total budget of the work [1]. Finally, solutions are proposed to the problems identified within the work, based on the criteria of Lean Construction. The problems encountered and their possible solutions can serve as a guide for future civil works projects, which seek to obtain high levels of productivity, competitiveness and profitability.
