A Confirmatory Framework PLS-SEM for Construction Waste Reduction as Part of Achieving Sustainable Development Goals of a Building

Abstract

As a result of rapid population growth, an exponentially growing human population, and industrial expansion, it has become increasingly difficult to manage municipal solid wastes throughout the world. Decentralized waste management systems have created difficult situations in developing countries such as Malaysia. Wastes generated in the country, due to various cultural, social, and religious activities, organic and contributing to environmental pollution (air, water, and soil) and human health troubles. A questionnaire survey was participated by 220 construction professionals in Malaysia using structured and semi-structured methods. The framework was assessed using A partial least square structural equation modeling (PLS-SEM) to target sustainable development goals (SDG). Statistical analysis results indicate a significant effect between SCW management, since(r(270)=.687, P<0.001). Improving factors has strong relationship with SCW management, since(r(270)=.723, P<0.001). The mediation results also suggested a significant indirect positive effect of improving factors drivers on SCW management through policy-related factors sinceβ=0.688, t=8.254, P<0.001, 95% CI for β=0.536,0.866. Finally, policy-related factors construct has a strong relationship with SCWM) management, since(r(270)=.811, P<0.001) With the R Square of 0.787 and 0.785. The developed framework can improve construction waste management in the construction industry and enhance construction waste management to achieve global sustainable development goals. The findings show that one of the most critical issues of enhancing profitability is using preventive policies to reduce construction waste. This study could guide construction industry stakeholders in identifying the different waste management features during a building project's construction and design stage

Beneficial Effects of 3D BIM for Pre-Empting Waste during the Planning and Design Stage of Building and Waste Reduction Strategies

“…It is estimated that design decisions made long before the actual execution of the project can reduce around 30% of waste [7]. Construction waste can be effectively reduced at the planning and design stage, as per the literature, because vari-ous design alternatives can be critically examined in terms of material selection, structural sharpness, size, and complicity, all of which significantly impact waste generation [8]. The smart application of the material supply chain at a construction site during the execution phase is another component of waste mitigation.…”

“…BIM can help to achieve the project's target quality, assist in the estimation of accurate time and quantity take-off schedules, and lower the project's costs. BIM may adopt efficient design methods that significantly reduce the waste output, reduce the energy usage, and the facilitate passive design approaches [8]. The impact of BIM implementation on sustainable construction practices and the current trends in BIM application during the project design phase have been investigated.…”

“…Therefore, normative approaches to BIM have been used for construction waste management [11][12][13]. The effectiveness of construction improvement opportunities can be assessed by including waste identification or reduction methods in flow operations, collaboration with value-adding strategies, new management tools, and appropriate training programmes [8]. According to Salihi [7], various elements and limitations influence the development of waste due to the building's design, including the material selection, communication complexity, and coordination of the construction [8].…”

According to Salihi [7], various elements and limitations influence the development of waste due to the building's design, including the material selection, communication complexity, and coordination of the construction [8]. According to the literature, a few methodologies might be utilised in order to assess and aid in construction waste reduction efficacy for on-site decision making during the planning and design and pre-construction phases.…”

The Mediating Role of Policy-Related Factors in the Relationship between Practice of Waste Generation and Sustainable Construction Waste Minimisation: PLS-SEM

“…Establishing a relationship between the economic, environmental, and social aspects of building design, construction, and use is essential for sustainable construction. Indeed, environmentally friendly construction is important for achieving sustainable development [22].…”
