A Review Study on Lean Implementation for Construction Waste Reduction

The building sector has a significant impact on how economically and socially a country develops. It boosts economic growth and contributes to the advancement of infrastructure in countries. Despite the positive consequences of the construction field, it frequently comes with several challenges that may lead to material waste, delays, and budget excesses. However, the attempts to find solutions to the waste issues on construction sites have been meagre. Construction waste may be classified as a complicated and multidimensional problem because of its hazy, interconnected nature, which makes it difficult to address. Lean construction techniques are excellent at managing the construction process and could address inefficiencies and non-value-adding processes. The main topics of identifying lean construction principles and practices for eliminating waste in construction projects are explicitly discussed. The appropriate database was used to perform the literature studies. The challenges of labour, supply chain, leadership, and just-in-time (JIT) production were some of the obstacles to executing lean construction. By identifying the pertinent amounts of waste-generating variables and the best tools to use, industry stakeholders may create strategies to manage construction waste more successfully. This paper will make a significant contribution to the field's understanding of how businesses can better structure lean implementation procedures for long-term success. The education of lean tools deployment is necessary for the workforce, the engagement of stakeholders in utilising lean tools and the fostering of lean culture is required for continuous improvement. This study supports previous literature reviews and other case disciplines that have affirmed the tools of lean construction in boosting effectiveness through the elimination of waste and optimization of resources.
