Abstract:
In the aftermath of natural disasters, the selection of the most suitable construction method is vital for rebuilding resilient and sustainable communities. This research sought to identify and evaluate construction methods best suited for post-disaster scenarios. An exhaustive literature review initially led to the identification of five prominent construction methods: Traditional, Modular, Prefab, Wooden Framework, and Steel Framework. Subsequently, 150 construction factors were discerned from the literature. Utilizing the Delphi technique, a rigorous multi-phase evaluation process was employed, ultimately distilling the factors to a core 31. These factors were strategically categorized via SWOT analysis, emphasizing their impact on each construction method. A unique scoring system was developed, where each factor was weighed against every construction method on a Likert scale. By leveraging the Euclidean Distance formula, a comprehensive ranking of the construction methods was established. The results positioned Modular and Prefab construction as the most suitable methods for post-disaster rebuilding, with close Opportunity-Strength scores. In contrast, Traditional Construction ranked third, while Wooden and Steel Framework methods exhibited proximity in their scores but lagged in comparison to the leading methods. This research contributes a novel and holistic approach to decision-making in post-disaster construction scenarios, emphasizing the importance of method selection in enhancing resilience and sustainability in rebuilt communities.
