ANÁLISE DO CONHECIMENTO DOS PROFISSIONAIS DA CONSTRUÇÃO CIVIL SOBRE OS RESÍDUOS DE CONSTRUÇÃO CIVIL E DEMOLIÇÃO NA CIDADE DE CAMPO MOURÃO - PR

The construction industry is responsible for generating a large volume of solid waste from construction and demolition, which pose a serious problem in many Brazilian cities, mainly due to irregular disposal of these residues. Even with the existence of rules and laws that establish guidelines for waste management from construction and demolition, there is still an inefficiency of decision making regarding the proper management of such waste. This study aims to analyze the knowledge rate of construction professionals, regarding the management of waste from construction and demolition from a case study in Campo Mourao-PR. For data collection, it was developed and implemented a structured questionnaire to 53 professionals, civil engineers and architects, registered in the Regional Association of Engineers and Architects of Campo Mourao - AREA. In the study it was observed that despite having knowledge of the law involving waste management of construction, it is necessary that these professionals have education and information about waste minimization and recycling, as well as investments and oversight to prevent irregular disposal leading environmental impact.O setor da construção civil é responsável pela geração de um grande volume de resíduos sólidos de construção civil e demolição que representam um grave problema em muitas cidades brasileiras devido, principalmente, a disposição irregular desses resíduos. Mesmo com a existência de normas e leis que estabelecem diretrizes para gestão dos resíduos de construção civil e demolição, ainda há uma ineficiência da tomada de decisão em relação a gestão correta desses resíduos. Este trabalho tem como objetivo analisar o grau de conhecimento dos profissionais da construção civil, em relação a gestão dos resíduos de construção civil e demolição, a partir de um estudo de caso na cidade de Campo Mourão-PR. Para a coleta de dados foi elaborado e aplicado um questionário estruturado a 53 profissionais, engenheiros civis e arquitetos, cadastrados na Associação Regional de Engenheiros e Arquitetos de Campo Mourão – AREA. Com o estudo observou-se que apesar dos profissionais terem conhecimento sobre a legislação que envolve a gestão dos resíduos de construção civil, é necessário educação e informação sobre a minimização e reciclagem desses resíduos, bem como, investimentos e fiscalização para evitar o descarte irregular levando a impactos ambientais

Smart Cities Maturity Model—A Multicriteria Approach

The concept of smart cities has gained relevance over the past few years. Public managers have been planning investments to turn their cities into smart cities. Maturity models can help managers to monitor the performance of urban indicators; however, these maturity models are not always capable of meeting their proposed goals. In this sense, this research aims to develop a maturity model that ranks the “smartness” of a city based on social and technological indicators. The Smart Cities Maturity Model (MMSC) variables were extracted from ISO’s 37153:2017, 37120:2018, 37107:2019. The MMSC is structured on a hybrid TOPSIS multicriteria decision-making method. In this paper, we modified TOPSIS and used it to generate a synthetic indicator, called smart index, that designates the level of maturity of a real city. For this change to be possible, we fixed some alternatives and changed the positive ideal and negative ideal solution. The methodology is proven to be very efficient in measuring the smart city maturity level, and it can be easily adapted for the upcoming ISOs
