Resumo Para a proposição de alternativas e estratégias de gerenciamento de resíduos de construção e demolição (RCD), é essencial a caracterização qualitativa e quantitativa dos resíduos. As ferramentas de apoio à gestão integrada de RCD tem sido de grande auxílio para identificar as melhores alternativas e estratégias. Este artigo tem como objetivo desenvolver um sistema computacional (software) que dê subsídios à gestão integrada de RCD para municípios brasileiros. O software foi dividido em quatro etapas: aquisição de conhecimentos (coleta de dados), estruturação do sistema (ferramentas do sistema), codificação e validação, a partir de um estudo de caso. Conclui-se, que a ferramenta computacional desenvolvida, testada com um banco de dados robusto, acerca da gestão de RCD em municípios, possibilita identificar uma melhor alternativa de gestão, considerando as diferentes realidades de cada município e de cada obra.

Abstract Knowledge of the qualitative and quantitative composition of waste is essentialin order to propose alternatives and strategies for construction and demolition waste (CDW) management. Tools to support the integrated management of CDW have been of great help in identifying the best management alternatives. This article aims to develop a computational system (software) which supports the integrated management of CDW for Brazilian municipalities. The software was divided into four stages: knowledge acquisition (data collection), system structuring (system tools), coding and validation, all based on a case study. In conclusion, the computational tool developed and tested with a robust database for managing CDW in municipalities makes it possible to identify better management alternatives, considering the different realities of each municipality and each construction project.

ABSTRACT In order to planning the Construction and Demolition Waste (CDW) management approach on a construction site, it is necessary to have a prior knowledge of what is being generated (qualitative analysis), the quantity that is being generated (quantitative analysis), and what is the proper final destination assigned to this material. This article proposes a new method to estimate CDW generation in Brazil from a qualitative and quantitative analysis of CDW generation in worksites. For the waste characterization, it was used the compression test with energy of Standard Proctor Test, granulometric analysis, microstructure analysis and direct shear tests. For the quantitative data collection, the research was limited to worksites of residential or commercial multi-story buildings, with reinforced concrete structure, which is the most common type used in Brazil. The data on the number of waste bins removed monthly, transportation and final disposal, CDW management costs, and constructive process were obtained from the construction companies.
