Explorando la relación entre los métodos de diseño lean y la reducción de residuos de construcción y demolición: tres estudios de caso de proyectos hospitalarios en California

Abstract

The lean ideal is to deliver customer value without waste. Traditional sustainability outcomes, which are attributed to the pursuit of the lean ideal in construction projects, consisted of economic outcomes instead of environmental outcomes. This paper explores how lean design methods can reduce construction and demolition (C&D) waste and contribute to environmental sustainability. Three case studies are conducted to analyze three hospital projects in California that employed lean tools and methods during design. These three cases demonstrate that C&D waste reduction (e.g., recycling construction waste, reducing material use, and enhancing recovery after use) can be indirectly achieved by economic waste reduction. Testable hypotheses were generated from the case study findings and were proposed as future research topics.

Comparing Team Interactions in Traditional and BIM-Lean Design Management

“…Herrera et al [41] summarized 19 lean design management (LDM) practices for the design phase of construction projects, namely, the early involvement of specialist designers and builders [42,43], the exhaustive definition of all the requirements of stakeholders and systematic client participation [44,45], the simultaneous design of the product and the process [46,47], the implementation of design planning activities [38,48], the collection of data for planning [49], collaborative and systematic planning, gradual planning, constraint management [21,50], coordination among specialist designers [42,51], collaborative problem-solving, the causal analysis of problems, monitoring problem solving processes [38,46], multiple option decision making, the examination of all available information for decision making, the collection of data for decision making [47,48], collaborative decision making [52], and monitoring decision-making processes [53,54]. Problem solving always requires decision making to solve the challenge, so in these cases, decision making is reactive; however, there may be instances of proactive design decision-making in the management requirements, programming, and design development process [55].…”

Grau de adoção dos Princípios do Lean Construction em dois canteiros de obras localizados no munícipio de Belém

“…Uma das alternativas que as empresas têm buscado é a adoção das práticas do Lean Construction [LC], uma vez que possibilitam a otimização de processos (Fabro et al, 2020), redução das perdas e desperdícios (Pheng, Shang, & Peter, 2016;Salgin, Arroyo & Ballard, 2016), ganhos econômicos (Ballard et al, 2008;Ballard, 2009), ganhos com a sustentabilidade (Saggin et al,2015;Almeida & Picchi, 2018), e ganhos ambientais (Golzapoor & Gonzáles, 2013;Ghosh et al, 2014).…”

A Multiplatform BIM-Integrated Construction Waste Quantification Model during Design Phase. The Case of the Structural System in a Spanish Building

“…Within the last decade, many research efforts have therefore been made to understand the causes of waste in construction projects, to assess its impact, and to propose eco-efficient strategies and best practices for its reduction, reuse, and recycling [7][8][9][10][11][12][13]. Furthermore, several studies have focused on the development of construction and demolition waste (CDW) quantification models [14][15][16][17] to support designers with data for appropriate decision-making at the design stage.…”
