The great development of civil construction is promoting a further improvement of the sector's activities. This promotes a change in thinking about works, their methods of management and planning. Labor is a factor that has relevance when related to planning, because it can have variations in terms, costs and quality. Thus, in this study, an analysis of labor productivity was performed for the performance of the conventional masonry service, also studying its material consumption and waste in order to determine its yield, amount of material used, waste generated and cost. After obtaining the data through comparisons with TCPO productivity indices, it was possible to determine how effective the team productivity was; With the analysis of the projects and the amount of materials used, it was possible to determine the consumption of materials and also through the input of materials and the amount of services performed, the indicators of waste were determined. Cumulative RUP values for masons ranged from 0.38 Hh / m² to 0.63 Hh / m², for the janitor ranged from 0.19 Hh / m² to 0.41 Hh / m². The unit consumption of brick was 16.71 un / m², cement 189.47 kg / m³, hydrated lime 151.58 kg / m³ and sand 0.76 m³ / m³. The gravimetric composition obtained presented 63% of bricks and 37% of mortar. Material waste was 2.23% for bricks, 4.37% for cement, 4.36% for hydrated lime and 6.17% for sand. The rate of material loss for masonry was 0.0024 m³ / m². The cost comparison presented had a variation for bricklayers of 20.75% cheaper compared to the values established by TCPO and 554.32% cheaper than SINAPI; for the servant, the values were 18.75% cheaper than TCPO and 114.06% cheaper than SINAPI. Comparing the values obtained with the TCPO, it was observed that the services presented positive values and it was possible to relate the good results with the tools and the working methods of the team, allowing a better understanding of the factors that influence the productivity, in the material consumption. and the waste that occurs in the works. |
