Analysing the alignment between lean construction and circular economy in prefabricated construction

With the recurring challenge of resources scarcity in the world, the construction industry needs to shift its attention towards sustainable practices. Prefabricated construction (PC) or modular construction has become increasingly popular in recent with its potential solution for the challenges faced, through increase of efficiency and reduction of waste. Some researchers have explored the integration of lean construction (LE) and circular economy (CE) into PC projects and highlights the benefits. However, they conclude that the implementation is in its early days and require a need for research as it holds significant potential in transition into a sustainable industry. This paper aims to exploring the alignment between CE and LC in PC through relevant resources to understand the full extent on this topic. The paper presents the research findings of 25 relevant publications that met the inclusion criteria in a statistical manner. This is to identify and summarise the known body of knowledge relevant to the topic. It shows that there is a strong link between focusing on the whole process for design, construction, and end-of-life of a building. Content was examined to discover what type and application of PC and relevant benefits and/or limitations.
