Construction professionals work in silos and use traditional design and construction methods. The growing demand for rapidly built and high-quality construction is making off-site manufacturing mainstream. Studies have shown that collaboration among all stakeholders is a necessary component for success in the construction of such buildings. This multidisciplinary study of an existing concrete hotel aims to explore an alternative structural design in mass timber or volumetric modular construction. To this end, the reinforced concrete floor plan of Club Med de Charlevoix in Quebec, Canada, was used as a benchmark for two different structural systems. The first strategy investigated CLT (cross-laminated timber) and glulam columns to replicate the reinforced concrete system (column–slab), while the second involved maximum prefabrication (volumetric modular construction). Both mass timber and volumetric modular strategies can lead to a smaller carbon footprint. The main conclusion is that the plan should be designed from the outset to be either traditional or prefabricated since major changes are required if the choice is made to switch from one system to the other. Moreover, when structural systems maximize off-site construction, such as volumetric modular construction, the various professions need to be included during early planning. This is necessary to avoid task duplication and prevent the neglect of considerations such as manufacturable dimensions and partition organization.

Over the past decades, prefabrication has emerged as a sustainable construction practice, with its performance significantly affected by the efficiency of production lines for the prefabricated components (PCs). However, insights from the industry reveal that selecting suppliers for PCs production lines has become increasingly challenging due to evolving, uncertain demands and complexity. Such issue negatively impacts PCs production performance, which in turn, affects overall efficiency of prefabrication. Despite previous research focusing on various PCs supplier selection criteria, there is limited research concerning its improvement in aligning with current industrial demands. Hence, this study developed an integrated AHP-improved VIKOR decision making framework with the advanced Lean principles incorporated, to enhance the efficiency of selected PCs production line suppliers. To achieve this, a Lean-based AHP-Improved VIKOR evaluation framework, including general criteria and specific criteria, was designed via an extensive literature review and expert interviews. Lastly, the developed framework was validated via a real-world case with Yizhong Construction Co., Ltd. in China. It demonstrates that this developed evaluation framework can be a valuable tool for selecting PCs production line suppliers, enhancing its efficiency through the lens of lean, and advancing prefabrication in developing countries.

Prefabrication is increasingly recognized as a sustainable construction practice, with the efficiency of prefabricated component (PC) production lines playing a critical role in its success. However, supplier selection for PC production lines has become more complex due to evolving industrial demands, uncertain supply chain conditions, and operational complexities. This study addresses this gap by developing a lean-based AHP–improved VIKOR decision-making framework to enhance the supplier selection for PC production lines. The framework integrates advanced lean principles with universal and specific evaluation criteria, identified through a comprehensive literature review and expert interviews. Its validity was tested via a real-world case study with Yizhong Construction Co., Ltd., Tianjin, China. The results show that the three suppliers are ranked as Zhongjian > Tianyi > Xindadi, where Zhongjian is the best supplier in this case study, with a VIKOR index of 0.156. The findings show that the developed framework can improve the supplier selection efficiency by aligning with lean principles and enhancing the performance of PC production lines. By addressing the challenges of PC supplier selection, this study provides a practical tool to advance the adoption of prefabrication in construction. Furthermore, it contributes to the development of the PC industry by offering a robust method for the selection of suitable suppliers, which can help to optimize the production efficiency and support sustainable practices in construction.
