Sustainable Value on Construction Projects and Lean Construction

Abstract

Lean production is a systemic approach to meeting customer expectations, whatever they value, by reducing waste. At first glance, lean then could only contribute to sustainability, while sustainability is achieved only if the customer values sustainability. The paper has two objectives. One is to examine whether sustainability is feasible using lean production with sustainability as an added value. The second objective is to examine how current lean construction tools and methods impact the construction and operation of sustainable facilities. The authors also suggest how these lean construction tools and methods have evolved to contribute to green construction. For this study, the authors interviewed lean adopters and conducted literature surveys on lean principles and methods, and its impacts on the economic, social and environmental sustainability.

Relação entre construção enxuta e sustentabilidade

“…Afirma-se que, em paralelo ao ganho de produtividade e qualidade, a utilização de pré-fabricados durante a construção pode acarretar no aumento do consumo de energia e na maior produção de gases poluentes (BAE; KIM, 2007KIM, , 2008 Passando para o lado da sustentabilidade, problemas foram identificados na interação entre os conceitos decorrentes da aplicação de práticas sustentáveis. Afirma-se que a abordagem utilizada para aplicação das certificações de sustentabilidade pode prejudicar a ação da construção enxuta.…”

Lean and Cleaner Production

“…Luo et al (2005) applied the lean concept to prefabrication and stated that lean could contribute to improve quality Koskela 1998) and supply chain and reduce waste. Bae and Kim (2007) found that different lean applications might have different results on the three pillars of sustainable development (i.e. economic, social and environmental sustainability).…”

Green Building and Lean Management: Synergies and Conflicts

“…However, this Lean method can not only be used for economic purposes, but also for social and environmental purposes by inserting downstream data into the map. Not only time and stock, but also a waste of resources, pollutions, resource use, security and interaction can be depicted (Bae et al, 2007). The most efficient and sustainable way to use VSM is when the card is created together with the employees.…”
