At present time, the construction waste (CW) represents a major challenge for the segment and its management during the production of buildings, for it promotes at the construction sites a reality linked to the management model of each construction company. It is then necessary to broaden the understanding of business management and integrate it to the concepts of environmental management. A new model for managing construction sites to be able to enable the management of CW and contribute positively to the serious problem of solid waste management in Brazilian cities is required. The research aimed to identify and analyze the management of construction waste (MCW) within the construction sites of residential buildings in the city of Cuiabá, from the application of a tool and instruments of analysis and observation, which measured quantitatively and qualitatively this management. Also aimed to identify to evaluat the model MCW present at the construction site and the interrelationship between the management of the construction site and management of construction waste, from a quantitative and qualitative analysis of simple technological improvements and innovations implemented. To achieve these goals, six of the nine largest companies in this segment, both regional and national, were studied, and which represented over 50% of the market for square meter in construction and projects delivered in 2013. In each company, two construction sites were surveyed, bringing the total to twelve participant In the analysis of the results it can be seen in these plots, actions and practices regarding the introduction of improvements, and technological innovations related to managing the construction site, although still preliminary to satisfactory results regarding the management of construction waste. By integrating these actions to the results obtained for model CW implanted in the construction sites of the companies, it was found that 83% of the constructions work with management construction waste insufficient without contribution or positive impact on the construction supply chain model. Considering all the aspects analyzed, for new buildings in the city of Cuiabá, the results indicated an average removed on construction sites of construction waste 199 kg/m2 built. Compared to the wider national value of 150 kg/m2 built, the research result is 25% higher; compared to the value reported by the Municipality of Cuiabá for developing project of construction waste management for new buildings, 120 kg/m² built, the research result is 40% higher.
