Analysis of labor performance in masonry work in two-story houses in the city of Cuenca
Main Article Content
Abstract
Introduction. This article is based on the analysis of labor performance in masonry in housing in the city of Cuenca, which directly influences productivity and is a crucial part of the economy of a nation. The yields used in the budgets and programming of works, must be based on multiple observations and statistical analysis, in the companies dedicated to the construction many of the economic losses are affected by the human factor and many times they are not identified and quantified. Objective. To analyze the labor yields in masonry items in houses of up to two floors in the city of Cuenca, comparing the results with the information of the Chamber of Construction of Cuenca to generate strategies to improve performance. Methodology. This study was conducted in four stages: in the first stage, the collection of data and the calculation of labor performance in masonry items, in the second stage, the comparison and analysis of data with the Chamber of Construction of Cuenca, in the third stage, a literature review was conducted and a strategy was defined to improve labor performance in masonry items, in the fourth stage, recommendations of technical specifications and the correct masonry construction process are given. Results. Through the methodology applied, the results show that for the five masonry items under study: industrial brick, handmade brick, exposed brick, pumice block and mixed block (pumice-concrete), the labor yields are lower than those of the Cuenca Chamber of Construction, except for industrial brick. Conclusion. Labor yields are affected by some factors that negatively affect productivity, but by implementing the strategy of training construction workers, a significant improvement is expected.
