Abstract
In today’s context, where architectural quality, construction speed, and the sustainability of building performance have simultaneously gained significant importance, selecting an appropriate construction method has become one of the major challenges in the design and housing construction process. Industrialized, conventional, and hybrid construction methods each possess distinct characteristics, advantages, and limitations that influence the quality and long-term performance of buildings. Given the concurrent importance of quality, speed, and sustainability, the lack of a precise analytical basis for evaluating construction methods has made the optimal selection process ambiguous, underscoring the need for this research. The innovation of this paper lies in the development of an integrated analytical framework for the simultaneous assessment of the three dimensions of “design, construction, and maintenance.” Using a comparative research strategy, this study identified specialized indicators within the aforementioned domains. Subsequently, by transforming qualitative spectra into quantitative values, the coding and evaluation processes were conducted in two stages: intra-group assessment and the final comparison of shared indicators. The results of the analyses indicate that, in the comprehensive evaluation of performance indicators, the “industrial hybrid method” achieved the highest ranking and demonstrated greater efficiency compared to the “conventional hybrid method.” The findings further reveal that although industrialized construction methods excel in precision, quality, and execution speed, they face limitations in areas such as flexibility. Ultimately, the paper proposes reliance on an optimized hybrid approach. The integration of conventional and industrial construction methods can provide a balanced solution to the multifaceted demands of contemporary residential projects while improving building quality and durability and accelerating construction.
