Application of lean manufacturing in construction management

Abstract

The construction industry in recent decades has been facing internal and external pressures, such as financial crisis, industry competitiveness and increased importance of quality required by the client. Because it is a sector, which has a low level of productivity, and high levels of waste, both with materials such as with labor, it is necessary to search for new management practices and production control. The development of a productive environment which aims to reduce waste, costs and deadlines, meeting customer needs and increasing efficiency and productivity in construction sites, made the application of the concepts of Lean Manufacturing in Civil works broke old paradigms in this area. In this way, this work has as objective the study of the implementation of Lean Manufacturing and its effect on the construction management, through the development of case studies on construction sites, where these concepts were applied and the results obtained are exposed in this work.

The DAWN readiness model to assess the level of use of Industry 4.0 technologies in the construction industry in Brazil

“…The score of all these companies together was 1067.7, reaching a Ra of 6.59, considered low readiness level, while it was expected that these companies, for being the largest in Brazil, could achieve a medium level score of readiness. This finding reinforces Aureliano et al (2019) and Temidayo et al (2020), who claim that construction professionals in Brazil need to know better the main technologies of I4.0 that can be used in the CI.…”

“…As it is a sector with a low level of productivity and high levels of waste, it is necessary to seek new management and production control practices. Nevertheless, CI professionals are unaware of the main technologies of C4.0 or do not know many applications for them (Aureliano et al, 2019;Temidayo et al, 2020). Initially this study identified 16 technologies linked to I4.0 in the academic literature, but as three did not present any application in construction (machine to machine, Internet of Services (IoS) and QR-Code), this study has considered only the remaining 13, presented in Section 2.4.…”

“…CI is a capital-intensive sector of high economic complexity, due to the large number of areas involved in its activities, making it essential to use tools to obtain improvements in its management, as this sector is full of complex problems (Al-Sabah and Abdulrahim, 2021; Darko et al , 2020; Murtazova and Khadisov, 2022). Despite this, it is considered a sector with a low level of productivity, high levels of waste of materials and low labor qualification, factors that indicate the need to search for new management and production control practices (Aureliano et al , 2019; Chen et al , 2020a; Wu et al , 2019).…”

Implementação de tecnologias sustentáveis na indústria da construção civil - uma análise bibliométrica

“…Entretanto, o problema gerado pela pandemia do coronavírus em 2020, que afetou a economia mundial, fez com que a estimativa de contração da ICC de 4,8% do PIB mundial, fosse reduzida para apenas de 1,4% no setor. Apesar desse problema global relativo à COVID-19, outros problemas sistêmicos são identificados neste ramo, como por exemplo, o crescimento do número de empresas e o aumento da competitividade, além das constantes crises financeiras, o aumento da exigência de qualidade por parte dos clientes, o baixo nível de produtividade e os altos níveis de desperdícios de materiais e mão-de-obra pouco qualificada (Aureliano et al, 2019) Também, a ICC é caracterizada como um ramo de baixo desenvolvimento e de implementação de inovações, quando comparado com outros setores da economia. Após muitos anos de críticas e crises, esse cenário está mudando, de modo que a adoção de tecnologias de ponta está sendo cada vez mais implementadas (Wei et al, 2017).…”
