Análise da geração de resíduos de construção e demolição em obras de habitações populares horizontais: estudo de caso

Abstract

Due to the significant amount of waste generated by the construction sector and the increased production of affordable housing, it is important to determine the quantities of waste generated in this segment, to improve waste management and minimize losses in this type of venture. Therefore, this study's main objective is to analysis the waste created thro the procesugs of construction and demolition (CDW) of the constructions of horizontal social housing. Was proposed one waste measurement methodology. Then we performed a data surveys in affordable housing works in the municipalities of Ivoti and Lindolfo Collor. After obtaining this data and waste identified as classes of Resolution 307/2002 of CONAMA, we performed qualitative and quantitative analysis, identifying later the influence of design features buildings in waste generation. As a result, it was obtained a total of 3.16 m³ of waste on average in the six works of dwellings popular, with a rate of 0.054 m³/m². Through the analysis of projects studied the work it was found that the design features as Total built area (m²), internal walls densities (m / m²), economic index of compactness (%) and construction cost can influence the generation of CDW. Also the cost analysis it was noted that the use of CUB in the budget process would be more appropriate to the reality of the works studied than SINAPI, adopted in studies of financing. Finally, it can be said that the proposed methodology is feasible for the studied segment and allows quantification of Waste fairly easily.
