Análise de barreiras para redução de resíduos de construção civil no canteiro de obras em edificação comercial de médio porte no Brasil: uma aplicação do fuzzy-DEMATEL

Abstract

Civil construction is one of the industrial sectors that most impacts the environment, with large consumption of raw materials and generation of waste, which globally corresponds to 35% of the total generated. Of these, one has as a medium-sized commercial activity segment, with great savings, as the focus of the main construction companies in the country 50 largest companies in the country is used in the database of the Brazilian Chamber of Construction Industry (CBIC). From the point of view of the concept of sustainability, it is necessary to assess why construction companies commonly do not have an efficient Civil Construction Waste (CDW) management, or why some implementation attempts become frustrating. The objective of this work was to identify and evaluate the main barriers to RCC reduction in a medium-sized commercial construction site in Brazil. For reduction, an efficient bibliographic survey was carried out with a systematic to identify the barriers that make it difficult to reduce these losses, as validated by experts for this. Subsequently, the multicriteria fuzzy-DEMATEL method (Decision Making a Trial and Evaluation Laboratory) was used, which from the collection of data with more deterium managers, and the identification of their influence relationships. The results of government planning research that B6 (Lack of planning and management of the work of financial resources) are more important and more influential than B913 (Lack of current legislation and government incentives). These results are allowed for project managers and other stakeholders to implement focused on reducing results at the construction site.
