“…Besides highlighting the exemplifying role of public works, most of the opportunities identified by construction firms in an open question are within the scope of government. Firms support a combined system of bonus and penalties, including an increase in disposal fees which would lead to obtaining net benefits from conduction C&D waste management according to Yuan et al (2011), discounts in treatment fees depending on the quality of the waste, fines for incorrect procedures such as illegal dumping or mixed waste, bonuses for using more sustainable materials, techniques and construction methods, and advantages for having individualized site drawings, among other measures. Many of the improvements suggested by construction firms were found to be related with the establishment of environmental awareness and training programs for all the stakeholders.…”

In this paper, the implementation of effective waste management practices in construction projects and sites is analyzed, using data from a survey answered by 74 Spanish construction companies based in Catalonia. Most commonly implemented practices were found to be on-site cleanliness and order, correct storage of raw materials, and prioritization of the nearest authorized waste managers. The least widespread practices were the use of a mobile crusher on site, the creation of individualized drawings for each construction site, and the dissemination of the contents of the waste management plan to all workers, to help them to meet its requirements. Waste regulations for construction and demolition, and the corresponding construction waste management facilities, were designed before the recession in the Spanish construction sector. Current waste generation rates are still below predicted levels, and the infrastructure was designed for five times more waste generation. Even so, the percentage of reused and recycled waste currently amounts to 43%. Survey respondents highlighted various instruments and measures that would make the management of construction and demolition waste more sustainable. Most of the opportunities identified by construction firms are within the scope of government and related to a combined system of bonus and penalties and the establishment of environmental awareness and training programmes for all the stakeholders. Within the scope of authorized waste managers, firms suggested improvements such as the standardization of fees, a reduction of the time until the issue of waste management certificates, a higher number of inspections, and a change in the current model of a few large construction waste management facilities. This research is useful to better understand the current status of construction and demolition waste management in construction projects and sites. Thus, the results of this research will guide policy makers and relevant stakeholders such as contractors, clients, architects and engineers to achieve the EU target of recovering 70% of construction and demolition waste in 2020. In this sense, reliable information can help governments and professional associations to set future C&D waste management regulations, training programmes and dissemination tools, inspections, etc.Peer ReviewedPostprint (author's final draft

Cost-Benefit Analysis (CBA) is often employed to inform decision makers about the desirability of transport infrastructure investment options. One of the main limitations of traditional CBA approaches is that they do not provide a dynamic view that explicitly illustrates the cost and benefit relationships between component entities over time. This paper addresses this issue by describing a System Dynamics (SD) approach that can perform transport infrastructure CBA through the application of systems thinking to develop a causal-loop model that can subsequently be operationalised into an executable stock-and-flow model. Execution of this model readily enables sensitivity analysis of infrastructure investment options and visualisation of the cost-benefit behaviour of each variant over time. The utility of the approach is illustrated through a case study, the Co Chien Bridge project in Vietnam, using a model that incorporates conventional economic metrics and factors that measure indirect project benefits, such as impact on gross domestic product, unemployment rate, and total taxes gained from affected economic sectors.

“…De acordo com Yeheyis et al (2012), mais de 75% dos resíduos gerados pela indústria da Construção Civil têm potencial de valoração, reciclagem ou reuso. Yuan et al (2011) expõem que os benefícios econômicos obtidos por meio da reciclagem dos RCC são enormes, uma vez que estes são reinseridos na cadeia produtiva. Os autores, também comentam outras vantagens, tais como aumento da competitividade entre empresas ocasionada pela redução das despesas (principalmente de transporte, destinação e aquisição de matéria-prima); geração de receita em razão do ganho econômico obtido por meio da comercialização dos resíduos recicláveis; melhoria da imagem pública da empresa pela atenuação do encaminhamento de resíduos para aterros e a diminuição de velocidade de esgotamento dos "bota-foras".…”

RESUMOA Construção Civil consiste em importante agente de desenvolvimento do país. Contudo, responde por significativos impactos ambientais decorrentes de suas atividades, os quais se iniciam na extração das matérias-primas naturais, para execução de suas obras, e se estendem até o término do ciclo de vida destas. Nesse sentido, sistemas de gestão ambiental de edificações buscam garantir a inserção da Sustentabilidade no setor. Neste contexto, foi desenvolvida uma pesquisa qualitativa por meio de estudo de caso múltiplo, com abordagem exploratória e análise quantitativa. Esta pesquisa traz o levantamento e a análise de práticas de gerenciamento de Resíduos de Construção Civil (RCC) empregadas por nove obras localizadas na cidade de São Paulo. Para tal, foi elaborado um checklist constituído por itens baseados na Resolução Conama 307/2002 e em recomendações de sistemas de certificação Leed, Processo Aqua e Selo Casa Azul. A ferramenta de pesquisa foi submetida à avaliação de especialistas e, posteriormente, utilizada em visitas realizadas nas obras. Por meio da análise dos dados, pode-se concluir que procedimentos de logística reversa e reuso/reciclagem dos resíduos gerados nas obras estudadas, ainda consistem em práticas pouco utilizadas, sendo o descarte dos RCC em áreas licenciadas a principal forma de manejo relatada pelas construtoras pesquisadas.
